Polestar will use StoreDot batteries with silicon anode and ultra-fast charging

The race to have the best batteries will leave us with some of the most important alliances in the years to come. The last to announce a strategic agreement in this sense has been Polestar, recently landed in Spain with the Polestar 2, which has announced that will become a shareholder of StoreDotthe company that is developing ultra-fast-charging silicon batteries.

Polestar has announced a strategic investment in the Israeli company StoreDot, specialized in ultra-fast charging batteries. The announcement comes just a month after Volvo (Polestar’s parent company) did the same. In no case has the economic amount of the agreement been specified, which will be strategic for using “extremely” fast-charging batteries in future Polestar electric cars.

As part of this strategic agreement, Polestar has already started collaborating with StoreDot to explore the adaptation and application of its technology to the Swedish brand’s prototypes and development cars. In other words, StoreDot technology and its silicon anode cells are already being tested in Polestar electric cars, pilot projects that serve as a prelude to what will hit the market from 2024.

By 2024, StoreDot aims to produce batteries for electric cars capable of charging up to 100 miles of range in just five minutes. However, we will have to wait until 2026 to see StoreDot silicon anode batteries in Polestar cars. According to Thomas Ingenlath, CEO of Polestar, “charging and range anxiety are common concerns that prevent car owners Combustion cars make the switch to electric vehicles. (…) If our current pilot projects with StoreDot are successful, we could see these solutions implemented in Polestar cars in 2026.”

What is StoreDot battery technology?

The ultra-fast charging batteries that StoreDot promises are lithium batteries with silicon anode in their cells. These cells will be available in two formats: bag-type and cylindrical. In the latter case, the chosen format will be the 4680 (The name comes from its dimensions, 46 mm in diameter and 80 mm high). Perhaps the name sounds familiar to you, because they are the ones that Tesla has been talking about since his Battery Day.

StoreDot’s objective for the end of this year is to complete the development of the cells, achieving 1,000 charge and discharge cycles. The next step is to have a battery capable of recovering 160 kilometers of autonomy (100 miles) in five minutes, something that they have already tested in the laboratory, managing to keep the temperature at bay and that they hope to launch on the market in 2024.

This will be the first generation of batteries, called 100in5 (referring to its recharging capacity: 100 miles in 5 minutes). However, in StoreDot’s roadmap, which includes three generations of batteries, there are several different technologies. The second generation of batteries will use a semisolid electrolytewill be able to achieve 100 miles of autonomy in 3 minutes (100in3) and is scheduled to begin production in the year 2028.

The second generation will mean a 40% improvement over the first in terms of recharge times. The third generation of StoreDot batteries will have a completely solid electrolyte and are scheduled for 2032. Its creators assure that they will be able to recharge 160 kilometers of autonomy in 2 minutes, improving the times of the previous generation by 33%.
