Lithium metal battery to give electric vehicles greater range by 2025

new Lithium metal battery

The company SES has introduced a new generation of electric batteries that promises to double the energy density of current lithium-ion batteries. According to the company’s founder, these lithium-metal batteries could be commercially available within two to three years.

The SES company recently introduced a new electric battery that was billed as “revolutionary.” This lithium-metal battery promises to double the energy density of currently marketed lithium-ion batteries. By removing the graphite from the anode, SES has saved weight and space on its batteries.

A new generation of lithium-metal batteries?

Solid-state batteries have always been touted as the Holy Grail of electric vehicles. They promise to increase the range and reduce the charging time of electric vehicles. A way to convince even more consumers to switch to electric vehicles. The company SES is developing solid state batteries.

China’s Geely unveils Homtruck, an electric truck to compete with Tesla
Last week, the company presented a prototype of a lithium-metal battery. To put it simply, SES eliminated the graphite from the anode, which is the part of the battery that accepts lithium ions during charging. Instead, the new battery has a pure lithium metal anode. This saves space.

To accomplish this, SES had to find a way to handle pure lithium, a highly reactive metal. When used as an anode, pure lithium often leads to the premature death of batteries. To make lithium metal anodes safe and durable, the company found a way to channel the formation of dendrites. If they get too large, the dendrites can fill the gap between the anode and cathode and set the electrolyte on fire. This was the risk feared by most manufacturers.

Several automakers are already on board

SES is currently working with General Motors, Hyundai, Geely and Foxconn. The company is building a factory in Shanghai that should be completed in 2023. According to Qichao Hu, the company’s CEO: “Actually, it’s mainly salt. This new liquid is very stable on lithium metal, very safe, non-flammable, non-volatile, non-organic”.

A certified testing organization even drove a nail into a battery without causing a fire, which you can’t do with lithium-ion batteries developed today. The company monitors its batteries using artificial intelligence models trained on data collected from the batteries, looking for defects or variations that could potentially lead to problems.

Electric batteries are at the heart of what automakers are thinking about. They are the ones that will allow them to differentiate themselves by offering greater autonomy to their electric vehicles. Last year, for example, PSA announced the creation of a gigafactory in France to produce electric batteries. Electric vehicles are beginning to be democratized (in 2020, Norway sold more electric vehicles than thermal vehicles), but there are still gaps, particularly in terms of batteries.

Gearbest site is down, customers in total uncertainty

Inaccessible for several days, Gearbest seems dead. According to several sources, the owner of the famous Chinese high-tech e-commerce site is about to declare bankruptcy.
A sudden closure, which leaves the customers of AliExpress’ competitor distraught.

Gearbest brought to its knees by the COVID-19 pandemic

Gearbest has been inaccessible for several days and it seems that it is not ready to return. According to Gizchina, the parent company of AliExpress’ main competitor is about to declare bankruptcy. This former high-tech bargain spot would not have withstood the ravages of the COVID-19 pandemic.

The first signs were clear: soaring prices on its flagship products, policy changes that were hurting its affiliate partners, loss of customer service quality, pending refunds… the list is long.

Already in 2020, most of the site’s products were out of stock, and when customers did find what they were looking for, Gearbest had trouble fulfilling orders. Those that were were experiencing huge delays. With these logistic problems, a disastrous customer service, and prices not as attractive as before, customers started to desert the site in favor of other solutions like AliExpress and others.

Total uncertainty for the customers

For those who remained, the situation is complicated. With Gearbest’s sudden closure and without a word, customers who recently placed orders are being hurt.

One of them confirmed to our colleagues the impossibility of claiming a cancellation of his order of connected watch, which he has been waiting for a few months. Many other people with an active order should find themselves in the same case, the management of customer service is done mainly by a chat … available only on the site.

And since the refunds requested before the unavailability of the site are still desperately awaited, the situation is likely to become even more complicated at the time of the official closure of the online sales site.

The concern and discontent are similar on the side of the many sites that offer affiliate links to Gearbest. If they have allowed the site to grow and to make a good reputation, the vast majority of them have not received any affiliate income for many months. “They haven’t paid me the more than $1,000 they owe me since March 2020 and I haven’t received a single cent since then,” says one of the partners. In the meantime, the Chinese company is hiding in a morbid silence and refuses to comment on the situation

CBD Vaporizer – The New Trendy Tech Product for Stoners

cbd vaporizer reviewed

Cannabis consumption is quickly rising around the globe, with many countries like the US and Israel legalizing its use.

More and more cannabis enthusiasts prefer to vaporize CBD rather than smoke it through joints or ingesting hemp-based products. But to take advantage of all the benefits of the cannabidiol found in the plants, it is still necessary to know how to vaporize it well.

Here are some of our pieces of advice.

Why should you vaporizer cannabinoids?

If the vaporization of CBD meets a growing success, it is because it is much more effective than other modes of consumption of weed or cannabis.

The proportion of CBD absorbed by the body, also called bioavailability, is much more important when vaporizing the product. The bioavailability of CBD is thus around 20% when you use a weed vaporizer as opposed to about 8% by ingestion. Moreover, when you swallow hemp products, it may take some time before the effects are felt. When vaporizing your CBD, it is easier to benefit from CBD quickly and to dose your product. Besides, vaporizing CBD has the reputation of being healthier. Indeed, by vaporizing cannabinoids, you do not inhale the harmful substances produced by combustion. To get the most from your sessions, it is crucial to control the process to get the most out of your hemp and obtain the desired effects. This control is achieved by controlling the right vaporizing temperature and choosing the right vaporizer.

The Pax 3 vaporizer

Choosing the right vaporizing temperature

A vaporizing temperature that is too low will make the cannabinoids evaporate poorly. But if you overheat the product, the hemp will burn and thus emit toxic substances. To get the most of your product, the CBD should be vaporized between 160 and 220°C. The choice of the vaporizing temperature depends on the variety of cannabis and the desired effect. Each cannabinoid present in your hemp has its evaporation point: 180°C for CBD and 150 to 198°C for the different terpenes. If you want a calming and euphoric CBD to vaporize, you can heat the product between 160 and 180°C. The high effect is enhanced at higher temperatures above 190°C and up to 220°C.

Vaporizing CBD will then be more effective in relieving severe pain, sleep problems, or depressive states. Be careful, however, not to increase the vaporizer temperature too much, as the combustion of the plants happens from 220 to 230°C. Finally, if you use grass to vaporize CBD, the temperature must be modulated according to the plant’s moisture. A parched grass vaporizes very quickly and can require to revise the temperature downwards. On the contrary, if the plant is too wet, it can be challenging to extract the cannabinoids. Some vaporizers then make it possible to heat the cannabis between 130 and 150°C to make a flavonoid cycle before vaporizing the CBD.

Choosing the right CBD vaporizer

Quality equipment will allow you to vaporize your CBD effectively to enjoy all its benefits. Some models of vaporizers are versatile and can vaporize dry herbs, waxes, or even CBD oil. It is up to you to choose according to your needs.

It is advisable to prefer convection heating rather than conduction heating. Convection allows a gentler and more homogeneous extraction of cannabinoids while preserving the plant. The aromas of the hemp are thus better preserved, and the active ingredients are less denatured. Choosing a good device like the ones tested and reviewed on Cannavapos website gives you more possibilities to select the CBD vaporizer that suits you and test several cannabis varieties.

Snapchat launches group video calls for up to 16 people

Available today, Snapchat audio and video calls allow you to chat with a host of friends simultaneously.

Faced with an ever more powerful Instagram and a new formula that is not unanimously accepted, Snapchat must continue to attract new users if it wishes to survive. Its solution: diversify from its original formula and propose new functionalities. With group audio and video calls, the social network turns into a perfect messaging service for large groups of friends or large families.

Up to 32 people

Now, group members can initiate a call that will invite all users to join a conversation. If a friend cannot arrive for several minutes and a discussion is in progress, they can join the call as soon as they come. A total of 32 people can join an audio group call while video calls are limited to 16 people. It is less than the 50 users allowed by Facebook Messenger, whose function was largely inspired.

Of course, Snapchat requires, you can customize your face with filters during a video call. Chatting with a puppy head is funnier.

Operation Seduction

Snapchat takes advantage of this announcement to officialize the arrival of the mentions in the Stories. In other words: social network users will be able to identify someone in their posts and put a link to their Snapchat profile. A feature Instagram Stories users will recognize.

This week, Snap also aired its first television commercial with the mission of explaining what the application is for adults. Interestingly enough, Snapchat defines itself as a “camera” rather than a social network and shows grandparents using the app.

As a reminder, searches in Instagram’s code revealed the upcoming arrival of audio/video calls in the application. It is a new sector on which the two services will be able to wage war!

How To Clean and Free space on Your Macintosh

If you are a heavy Mac user or you have had it for years, it is possible you be wondering whether at times the cost was justifiable. The good news is that you may not have to buy a new Mac to continue enjoying the high speeds you took it out of the box.
In this article, we are going to look at how to improve the speeds and performance of your Macintosh and especially comment nettoyer son mac.

Many reasons could cause your Mac to run slow or experience a decline in performance. The two leading causes are old and performance; one is old age, the other is if your hard disk is full. In the case of old age, it’s possible your operating system was not designed to work with some of the apps in use. In other cases, some of the background processes have become muddled, that can happen when permissions are broken, or the machine wasn’t shut down properly.

At other times, it could be because you have so many things running at once when you start your machine. That also happens when the device isn’t properly shut down, and therefore apps are left running in the background for weeks. In case of a hard disk getting full, it becomes tedious to fetch files scattered all the storage area, which slows down the machine.

Cleaning Software

One of the easiest ways to clean your Mac is using cleaning software. A good example is the “Trim Enabler 4,” which automates the process for you. The software will cleverly monitor your SSD’s health, improve the overall performance of your Mac, and allow you to benchmark your Mac’s performance. You get to download a trial version here and to get a feel for how it works.

Cleaning Manually

Close Unnecessary Apps

If you choose to clean your Macintosh manually to speed it up, the first step is to close any background apps. It’s possible that you have numerous apps running in the background yet you haven’t used them for weeks.

Press “Cmd-Tab,” to see which programs are running; the App Switcher will open up and list all the open apps. To close the unused programs, press “Cmd-Q.” If you notice a program with a “Force Quit” option, close it, because it’s one of those unresponsive programs slowing your machine. In cases where you don’t need the unresponsive program, the best way is to uninstall it.

Power Hungry Applications

You can use the Activity Monitor located in the utility folder to view resource intensive application. You may also press “Cmd-space,” then type “activity,” then press “enter”.

Clean My Mac is a solid Application!

Next, you need to click “View,” and select Windowed processes. That’s important to avoid closing important processes that you aren’t supposed to close. Next, click the CPU button, and now to list all programs’ CPU usage, click the “%CPU” column. Do the same for Disk, Network, and Memory usages.

You may close any apps you see using a huge chunk of CPU, Memory, Network, and Disk by selecting the app with your mouse, and then clicking the “x” appearing at the Activity Monitor’s left-hand corner. Once you close it, update it if you haven’t done so for a while.

Disk Space

Your Mac needs at least 10% of your SSD space to be free for its use in reading and writing swap files. Contiguous free space is necessary for that to happen, which means that as a rule of thumb, you need to have a minimum of 20% free space. That will allow you to work and clean your files periodically while still allowing your machine free disk space for an optimal experience.

If you don’t have that much space left, simply your bigger media files to another storage device, and leave only data that you are working on. To find out how much space you have left, click the Apple Logo, and then click “About this Mac.” Next click on the storage tab, the app will calculate how much space is in use, and how it is used.

Overall, you will find that media apps use most of the space. You can also download software for managing space such as OmniDiskSweeper, and use it to free some space.

After freeing some disk space to about 15%, closing and then updating resource intensive apps, you should be able to see an improvement in speed of your Macintosh. We hope that you found this article to be informative, and useful.

Xbox One VS PS4 – Time to look at the numbers !

Xbox One: 35 million console consoles sold… versus 76 million PS4s sold!

According to reputed tech analysts, Microsoft has sold a total of 35 million Xbox One… compared to more than 76 million PS4s for Sony.

Unofficial figures for the Xbox One

 

For a few years now, Microsoft has refused to reveal the sales figures of its Xbox One console. The latest official results date back to November 2014, a time when Microsoft proudly announced that it had reached 10 million console sales. In early 2016, Electronic Arts announced that just under 20 million Xbox One units had found a home.

A silence that according to some people stems from a certain failure on the part of Microsoft, after an amazing run with their flagship. product Xbox 360 that held the expectations high at the PS3. On this new generation console, the PS4 has an impressive track record with more than 76 million consoles sold worldwide. According to Daniel Ahmad, a video game market data specialist, Microsoft has sold 35 million Xbox One units worldwide. A disappointing score for the American giant, well below PS4, which would have a hard time climbing to these numbers…

The PS4 and Xbox One hit the market at the end of 2013, only a few days apart. Sony’s console was rapidly able to take the lead on the American console, thanks in particular to a better price positioning, namely 399 euros for the PS4 versus 499 euros for the Xbox One. Added to this is a rather disastrous communication from Microsoft during the first few months, without forgetting the famous “exclusivity”, stronger and more numerous on PS4 than on Xbox One.

Credit Start Up To Target Generation Z And Millennials

The problem; the younger generation are increasingly wary of credit cards. They don’t want to be in debt like their parents’ generation. So wily credit card companies are attempting to challenge that.

Research has shown that just 33% of young Americans aged between 18-29 have a credit card, a fact that has caused concern amongst card providers.

But also, without credit cards, these younger people are finding it harder to build up a credit rating, which will enable them to take out a mortgage and get a foot on the property ladder later on.

Now there are several companies which are engaging with this generation, to offer them ways of building credit.

One of which is Deserve, who have recently changed their name from SelfScore. This is a start-up company which is based in Menlo Park.

The company which has worked together with international students, has come up with a card which is intended to be attractive to this lost generation of credit users.

Principally aimed at younger adults, teens and Generation Z, Deserve have made $12 million available in funds with partners from Accel, Aspect Ventures and more besides.

According to the company’s co-founder, Kalpesh Kapadia, these millennials are in a Catch 22 situation, whereby the lack of credit is perpetuating a problem in obtaining credit. To get off this treadmill they have been targeted by the firm.

Deserve believes that this age group should be given the opportunity to build up their credit rating, where other companies have given them the brush off.

Of course, there is always a risk with offering credit to people who have no credit history and the company will have to take the chance that their investment will not be repaid. But, as with all high risk credit ventures, they come with a higher interest rate to counter that eventuality.

Instead of using a credit rating score in order to decide who should be offered a credit card, Depend have another way of assessing the eligibility for their services.


Their novel method of deciding who should be given this line of credit is to use machine learning to find criteria such as self-discipline, employment, levels of education and reliability.

One of the investors from partner company Accel stated that this new method of assessing financial worthiness is very interesting and could be the way forward for the future.

This is a learning opportunity for the industry to determine who should be given credit, without already having a prior credit rating.

Whether Generation Z and the Millennials will embrace this technology and decide that they want to take up credit, remains to be seen. But for those that do, they are being given the chance to build their credit rating for the future.

More than that, this could be used as a way of helping to create a future with financial independence for this younger generation – which could help them to get mortgages later on.

It is possible that the younger generation have learned from their parents’ mistakes and have turned their backs on credit and the huge debts that go with it – and perhaps they cannot be blamed for that.

But what Deserve is offering could prove too good to be true – a way for them to obtain a credit rating, without having to first already have a credit history.

The Chinese company DJI offers a system for the detection of its drones.

A world leader, the Chinese firm markets a system that allows police forces to locate its drones near sensitive areas.

drones are dangerousThe rise of UAVs has, in turn, created an emerging but insistent demand: the possibility of detecting them.

The international regulations, which will be implemented in the coming months, provide, like the future European standards, that each aircraft must have a registration in the form of an electronic signature.

At the same time, sensitive areas around airports, nuclear power stations, and major public events are beginning to be equipped with sophisticated detection systems. The Chinese DJI, the world’s number one leisure drones, wants to occupy this field by offering the public authorities equipment capable of locating its drones, AeroScope, unveiled on 12 October in Brussels. A way to expand its activity, but also to watch over its image as a company respectful of sensitive data, which has been somewhat shaken up in recent months.

Two-thirds of the world market – AeroScope is a tracking system currently limited to DJI drones. The Shenzhen-based company has between 60 and 65 % of the market for leisure equipment, which is a significant basis. Also, this feature, which identifies – but not neutralizes – an aircraft, does not require any updates from the pilot. AeroScope is a receiver, available in mobile (medium size suitcase) or a fixed mode, able to detect – “up to a distance of 5 km”, say its designers – a small drone, identifying the wifi link that connects it to the pilot’s radio control. Once located, the AeroScope’s display receives telemetry data from the drone: GPS position, altitude, speed, but also the serial number of the aircraft as well as its direction and location from which it took off.

Two airports under test

DJI, which does not indicate the price of the equipment (which will have to be much cheaper than sophisticated detectors, derived from military radars, to be widely distributed), only indicates that it will be available in the coming weeks. In addition to airports – two of them are currently in the testing phase – AeroScope is intended for use by the police, for example, to monitor an event, or in prisons to detect the approach of suspect UAVs.

DJI matrice range of quadsThe challenge now is to convince the competition – Parrot, Yuneec, GoPro – to integrate a compatible wifi signature (DJI is willing to “open its protocol”) to make its drones like the DJI Care Mavic Pro identifiable. On the other hand, it will be more difficult for “homemade” quadcopters by enlightened amateurs. To protect consumer privacy, AeroScope will not automatically transmit personally identifiable information until required by regulation,” says DJI.

Offline Mode

Although nothing to date has substantiated these fears, DJI’s leaders have decided to take immediate action. A few days before presenting AeroScope, they announced the release of a “Local Data” mode to interrupt the Internet connection of the DJI GO 4 application to ensure that no data leaves the drone or tablet used to fly it. Even if it means depriving itself of certain information, such as local flight restrictions.

This electronic equipment, which no one can guarantee will be completely effective – particularly against UAVs flying in programmed mode – also allows DJI to take the lead while awaiting the introduction of registration and identification devices that will soon be imposed on recreational UAV users.

New LG Display: 80 inch 8K and 40 inches Oled TV Ultra HD in 2019

presentation of oled screens

On the occasion of the 2017 Europe Oled Day event, LG Display – the leading supplier of Oled screens for TVs – presented its plans for the coming years.

The growth of LG Display in the TV segment is impressive. By 2015, the manufacturer had only two customers: LG Electronics, of course, which carried the Oled technology, and Panasonic, which was one of the first TV manufacturers to make contact with the Korean company, Panasonic TX-65CZ950E.

Today, the company supplies 13 manufacturers (LG, Sony, Panasonic, Loewe, Philips, Skyworth, Metz, Konka, Grundig, Changhong, Vestel, Toshiba and Bang & Olufsen). As a result of this interest in Oled, a new P10 plant in Paju, South Korea will ensure that sufficient volumes are supplied to all manufacturers. In 2016, LG Display produced just under one million large-sized Oled tiles. This figure rises to almost 2 million this year, and LG Display is counting on 3 million units next year and more than 6 million in 2020.

In 2018, LG Display does not expect much change in the range. The manufacturer continues to supply 55,65 and 77-inch Ultra HD screens as well as a 55 inch Full HD screen.

lg oled tvThe first change in the range is expected to take place in 2019 with the arrival of the first 80-inch tiles supporting 8K definition. However, this definition is of little interest in Europe for example, where Ultra HD/4K content is already very limited.

While by 2020, Ultra HD content is expected to multiply through the streaming and democratization of Ultra HD Blu-ray, 8K content still seems to be inaccessible with current technical means (limited bandwidth on the Internet and via DTT multiplex). LG Display concentrates on design, especially with its original screens for professional display (double-sided, concave, convex, transparent) and also a few outlets in the consumer segment (window wallpaper screens, rollable and flexible).

Another information that does not appear in the presentation: LG Display prepares many Oled screens with a diagonal of 40 to 49 inches for the European market.
However, production of these screens is not expected until 2019. We can, therefore, expect to see commercialization by the end of 2019, or even early 2020. As far as fares are concerned, these tiles will not necessarily be cheap, and Oled 40 to 49-inch televisions should be sold at the same prices as 55-inch models, which offer economies of scale.

Finally, we asked LG Display President Sang-Deog Yeoux if Oled’s mid-sized screens for laptops and PC monitors would be developed. He simply told us that nothing was planned for the time being. The situation is therefore not about to improve on that front. The few laptops equipped with Oled screens and the only Oled monitor on the market (Dell UP3017Q) will, therefore, rely for some time on Oled tiles produced by Samsung Display.

Twitter Launch Transparency Center To Help Users Being Targetted By Political Ads

twitter the social network

In response to the criticism over the 2016 US presidential election, Twitter has unveiled its new ‘transparency center’ which will enforce tougher standards for political adverts on the social media platform.

This comes after the company were placed under fire for allowing adverts, which may have been Russian propaganda, in last year’s election.

The plan is that the Transparency Center will be able to show users the details of adverts on Twitter, with facts such as what length of time they have been up for and if they are aimed at you as a user.

If you think that an advert running on Twitter is unfair or there is something wrong about it, it will be possible to report it.

The media giant is especially concerned about political adverts and anything that may be seen as campaigning for a political party, person or cause.

In this new transparency center, readers will be able to discover more about these political ads and see which demographic have been picked out to be shown the adverts.

Additionally, the transparency center will show how much a certain political candidate, cause or campaign has spent on advertising.

Initially it will only be the USA where these initiatives will be focused, but in time, this information should also be available to be accessed all over the globe.

In a similar move, Facebook also announced that they were planning on increasing their transparency, with regards to advertising.

  • Twitter are also considering launching a premium version of their website which would be ad free for subscribers.
