160 km in 5 minutes, see StoreDot super fast charging in action

The Israeli startup StoreDot working on a new technology that will significantly accelerate loading electric batteries while increasing their duration of life. StoreDot estimates that their battery does not lose performance, even after more than 1,500 recharging cycles.

Currently, this ultra-fast technology can charge the equivalent of 160 km in just five minutes. The idea is to achieve a similar recharge in three minutes in 2028 and then in just two minutes in 2032.

StoreDot is an expert in so-called Extreme Fast Charging (XFC) for electric cars. This demonstration is not only of practical interest, but also and above all organic, as the longer the batteries will work, the less they need to be replaced and therefore thrown out. The ultimate goal of this research is therefore to reduce the environmental impact of the future overproduction of batteries for electric cars.

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

Patented active nanoparticles

These achievements are due to a technology based on nanoparticles patented active ingredients that accelerate diffusion ions and which replaceanode traditional in graphite Lithium-ion batteries, all optimized for artificial intelligence. Here, the algorithms make it possible 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 longevity of batteries electricity is fundamental, on the eve of a historic shift from thermal to all (or almost) electrified. This 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 on graphextracted from graphite, self-derived carbon. Its main advantage is to be 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 that can run 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 will charge an electric car in 5 minutes

Article by Marc Zaffagni on 25/08/2015

After smartphones that it 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 assures that it would only take five minutes to charge its battery called FlashBattery, which would offer a range of 480 kilometers.

Along with range, recharging time is one of the two main obstacles that still need to be removed, then electric cars can be set up as viable alternatives to the internal combustion engine. The first manufacturer or manufacturers to create “The” battery technology capable of meeting one of these requirements will win the jackpot. 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 Flash battery 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 still, StoreDot has just raised $ 18 million (15.5 million euros at the current price) to fund the development of this technology after already raising $ 42 million (36 million euros) from powerful investors such as Samsung. The start-up estimates that its technology can be sold in 2020. But what exactly is it? Futura-Sciences has already dedicated another article StoreDot and interviewed its founder and CEO Doron Myersdorf. The technology was originally developed for smartphones.

It is based on a nanostructure made of bioorganic materials that increase the ability to electrodes and electrolyte performance. More precisely, the quantum dots are formed by nanocrystals of 2.1 nanometer in diameter made of peptides of synthesis. In addition to outstanding performance, StoreDot also praises the ecological aspect of its innovation, which replaces organic compounds for metals heavy and toxic currently used in lithium-ion batteries or in cadmium. Just over a year ago, the company unveiled a prototype battery that recharges in 30 seconds. It took itself two to three years to produce a battery with the format and capacity as one standard model which could be charged in 60 seconds.

More promising technologies in competition

StoreDot is visibly confident in the possibilities of this technology and wants to apply it to electric cars. And to announce therefore that its FlashBattery equipped with 7,000 cells would only take five minutes to be fully charged. What’s more, the composition and architecture of this battery would quadruple the number of charge-discharge cycles for existing batteries, bringing it from 500 to 2,000. It is still unknown if StoreDot will be in pole position to market its process. For other start-ups, also with significant financial support, are also in the race.

We have already mentioned in these columns the work of Sakti3 which develops an advanced lithium-ion battery solid 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 has Seeo was born by wearing a technology to lithium-ion batteries able to double the autonomy. Called DryLyte, the process relies on a non-combustible solid electrolyte made by one polymer with nanostructure. At the end of 2014, Seeo, which is also a spin-off from Lawrence Berkeley Laboratory, raised $ 17 million (14.7 million euros), mainly from Samsung Ventures and Google.org. The batteries DryLyte is currently undergoing a nine-month evaluation program conducted in the United States by manufacturers cars Ford and General Motors.
