The Israeli startup StoreDot is working on a new technology designed to significantly accelerate the loading of electric batteries while increasing his duration of life. StoreDot estimates that its battery does not lose performance, even after more than 1,500 charge cycles.

At the moment, this ultra-fast technology can charge the equivalent of 160 km in just five minutes. The idea is to get an equivalent recharge in three minutes in 2028 and then in just two minutes in 2032.

StoreDot is an expert in what is known as fast loading (XFC) for electric vehicles. This demonstration is not only of practical interest, but also, and above all, ecological, since the longer the batteries work, the less it will be necessary to change them and, therefore, to dispose of them. The ultimate goal of this research is therefore to reduce the environmental impact of future overproduction of batteries for electric vehicles.

Its development program has already made it possible to produce batteries capable of exceeding 1,200 consecutive fast charge cycles without damage or loss of performance, unlike lithium ion batteries fast charge currently in use. StoreDot even estimates that this performance can be kept relatively high up to 1,700 cycles.

Patented active nanoparticles

These benefits are due to a technology based on patented active nanoparticles that accelerate the diffusion ions and which replace theanode traditional in graphite lithium ion batteries, all powered byartificial intelligence. Here, the algorithms allow you to automatically disconnect an overheated cell before reconnecting it once the problem is resolved. This avoids damaging it too much and damaging the surrounding cells. It also significantly reduces the risk of fire.

The problem of the useful life of batteries electricity is essential, on the eve of a historic step from thermal to all (or almost) electrified. That is why many companies and manufacturers are currently working on alternatives to the traditional lithium ion battery.

The Chinese GAC has even become the first manufacturer to market a model equipped with a battery based graffitiextracted from graphite, itself derived from carbon. Its main advantage is that it is faster to recharge, but also more resistant and therefore less prone to wear. For its part, the American startup Our Next Energy (ONE), for example, has developed a battery capable of traveling more than 1,200 km on a single charge. It also hopes to be able to market its first products by the end of 2023.

StoreDot wants to charge an electric car in 5 minutes

After the smartphones which promises to recharge in less than a minute, the set up Israeli StoreDot wants to adapt its bio-organic battery technology to electric vehicles. The company says it would only take five minutes to charge its battery called FlashBattery which would offer one autonomy of 480 kilometers.

Along with autonomy, recharging time is one of the two main obstacles that still need to be removed for this electric cars they can be considered as viable alternatives to the internal combustion engine. The first manufacturers to create “The” battery technology capable of meeting any of these requirements will be awarded. In recent months, several companies working on promising solutions have raised significant funds. Among these are StoreDotan Israeli start-up that promises it charge an electric car in record time. According to him, his FlashBattery will be able to offer a range of 480 kilometers after only five minutes of charging.

The promise seems bold given the current performance in this area. And yet, StoreDot has just raised $ 18 million (15.5 million euros at current price) to fund the development of this technology after having already raised $ 42 million (36 million euros) from powerful investors like Samsung . The start-up estimates that its technology could be marketed in 2020. But what exactly is it? Futura-Sciences has already dedicated an article to him StoreDot and interviewed its founder and CEO Doron Myersdorf. The technology was originally developed for smartphones.

It is based on a nanostructure made of bio-organic materials that increase the capacity of electrodes and electrolyte performance. More precisely, they are quantum dots formed from 2.1 nanocrystals nanometers of diameter made of peptides of synthesis. In addition to outstanding performance, StoreDot also praises the eco-friendly aspect of its innovation, which replaces organic compounds with metals heavy and toxic that is currently used in lithium ion batteries or in cadmium. Just over a year ago, the company unveiled a prototype battery that recharged in 30 seconds. It then took two to three years to produce a battery with the format and capacity of a standard model which could be loaded in 60 seconds.

Various promising technologies in competition

Visibly confident in the capabilities of this technology, StoreDot wants to apply it to electric cars. And to announce, therefore, that its FlashBattery equipped with 7,000 cells would only need five minutes to fully recharge. In addition, the composition and architecture of this battery would quadruple the number of charge-discharge cycles of existing batteries, from 500 to 2,000. It remains to be seen whether StoreDot will be in the top position to market its process. Because other start-ups, also with significant financial support, are also in the running.

We have already mentioned in these columns the work of Sakti3 which develops a state-of-the-art lithium-ion battery solid it is likely to double the battery life of smartphones and electric cars. The British company Dyson has invested 15 million dollars (14 million euros) in this spin-off founded in 2007 by a team of researchers from the University of Michigan (USA).

The same year, the company Watch was born carrying a technology for lithium ion batteries capable of doubling autonomy. Called DryLyte, the process is based on a non-flammable solid electrolyte made of a polymer with nanostructure. At the end of 2014, Seeo, which is also a spin-off of the Lawrence Berkeley lab, raised $ 17 million ($ 14.7 million), mostly from Samsung Ventures and Google.org. The batteries DryLyte they are currently undergoing a nine-month evaluation program conducted in the United States by manufacturers cars Ford and General Motors.
