the Israeli startup StoreDot is working on a new technology designed to significantly speed up the loading of electric batteries while increasing your duration of life. StoreDot estimates that your battery will not lose performance, even after more than 1,500 recharge cycles.

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

StoreDot specializes in the so-called Extreme Fast Charging (XFC) for electric vehicles. This demonstration is not only of practical interest, but also, and above all, ecological, because the longer the batteries work, the less they will have to be changed and therefore thrown away. The ultimate objective of this research is therefore to reduce the environmental impact of future overproduction of batteries for electric vehicles.

Its development program has already enabled the production of 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 remain relatively high up to 1,700 cycles.

Patented active nanoparticles

These performances are due to a technology based on nanoparticles patented active ingredients that accelerate diffusion ions and that replace theanode traditional in graphite Lithium-ion batteries, all optimized by artificial 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 lifespan problem batteries Electricity is essential, on the eve of a historic change from thermal to fully (or almost) electrified. That’s why many companies and manufacturers are currently working on alternatives to the traditional lithium-ion battery.

The Chinese GAC even became the first manufacturer to market a model equipped with a battery-based battery. grapheneextracted from graphite, itself derived carbon. Its main advantage is that it is faster to recharge, but also more resistant and therefore less subject to wear and tear. In turn, the American startup Our Next Energy (ONE), for example, has developed a battery capable of covering 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

article of Marc Zaffagni on 08/25/2015

After smartphones that promises to recharge in less than a minute, Israeli start-up StoreDot wants to adapt its bio-organic battery technology to electric vehicles. The company guarantees that it would take just five minutes to charge its battery called FlashBattery, which would offer a range of 480 kilometers.

Along with range, cooldown is one of the two main obstacles that still need to be removed in order for eletric cars can be placed as viable alternatives to the internal combustion engine. The first manufacturer(s) to create “The” battery technology capable of meeting any of these requirements will win the top prize. In recent months, several companies working on promising solutions have raised significant funds. Among these is StoreDotan Israeli start-up that promises charge an electric car in record time. According to him, his FlashBattery will be able to offer a range of 480 kilometers after just five minutes of charging.

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

It is based on a nanostructure made of bio-organic materials that increase the ability to electrodes and electrolytic performance. More precisely, they are quantum dots formed from nanocrystals of 2.1 nanometers in diameter made of peptides of synthesis. In addition to the excellent performance, StoreDot also praises the ecological aspect of its innovation that replaces organic compounds with metals heavy and toxic substances currently used in lithium-ion batteries or in cadmium. A little over a year ago, the company presented a prototype battery that recharged in 30 seconds. It then took two to three years to produce a battery with the shape and capacity of a standard model which can be charged in 60 seconds.

Several 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 need only five minutes to be fully recharged. In addition, the composition and architecture of this battery would quadruple the number of charge and discharge cycles of existing batteries, from 500 to 2,000. It remains to be seen whether StoreDot will be in pole position to commercialize 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 Shakti3 which develops a state-of-the-art lithium-ion battery solid will likely double the battery life of smartphones and eletric cars. The British company Dyson invested 15 million dollars (14 million euros) in this spin-off founded in 2007 by a team of researchers from the University of Michigan (United States).

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