StoreDot, an Israeli company that develops extreme fast-charging (XFC) battery tech for electric vehicles, announced the “world’s first” silicon-dominant battery prototypes this month that can be recharged in under 10 minutes. The cylindrical cells used by the company have a 4680 design — 46 millimeters wide x 80 millimeters long — which is popular among worldwide automakers, particularly Tesla.
The battery technology has been in production for 3 years and comprises five cell design patents, according to a statement released by StoreDot last week. According to the business, the design “improves throughput while also addressing safety and performance challenges generally linked with the hard case construction of cylindrical cells.”
StoreDot said it was currently working with Eve Energy, the firm’s Chinese manufacturing partner, to put up a production line. StoreDot Chief Executive Officer Dr. Doron Myersdorf stated, “Achieving the goal of extremely rapid charging the cylindrical cell within just 10 minutes has been on our timeline from day one.” “It’s critical that we can provide Electric Vehicle manufacturers with a variety of cell formats, leveraging our XFC technology, to conquer the major obstacles to EV [electric vehicle] possession: range and charging anxiety,” says the company. This relates to the worry of a battery running out in the middle of a journey and leaving the driver stranded at a charging station.
Myersdorf said it was in “advanced discussions” with several global automakers, with plans to “supply them with numerous XFC cells, allowing a rapid shift to a zero-emissions electric-powered future.” According to the company, the 4680-format battery, as well as the first-generation rapid-charging pouch cell, will be ready for mass production in 2024. StoreDot is also developing extreme energy density (XED) solid-state technologies, extending battery life and full production in 2028.
StoreDot, based in Herzliya, has been producing lithium ion-based battery solutions for the mobile and industrial industries since 2012, employing nanomaterials and inorganic and organic chemicals. According to the business, the technique changes the chemistry of traditional lithium-ion batteries, reducing charging periods for electric vehicles from hours to minutes. This innovation is primarily achieved by substituting graphite in the cell’s anode with metalloid nanoparticles, like silicon, to address major difficulties with safety, cell swelling, and cycle life during the charging process.
BP Ventures, the venture wing of the British global oil and gas corporation BP plc, Daimler AG, the manufacturer of Mercedes Benz vehicles, Japanese electrical conglomerate TDK, and Samsung Ventures are among StoreDot’s significant investors. To date, the firm has raised $130 million.
In 2019, StoreDot demonstrated the world’s first entire live charge of a two-wheeled electric car in five minutes using a tiny form factor of the XFC technology. It showed the scalability of the XFC batteries for various devices a year later by charging a commercial drone in five minutes. In January 2021, StoreDot released engineering samples of batteries, marking even another milestone.
