StoreDot and Polestar – 10% to 80% charge in 10 minutes

StoreDot and Polestar - 10% to 80% charge in 10 minutes

StoreDot & Polestar have demonstrated battery technology that charges an electric vehicle in just 10 minutes.

 

In the demo video seen here the companies charged a 77kWh battery pack powered by StoreDot’s extreme fast charging high energy (300Wh/kg) silicon-dominant battery cells, installed in a fully driveable verification Polestar 5 prototype, from 10% to 80% in under 10 minutes.

 

The vehicle saw a consistent charge rate of over 310kW for the entire test procedure and a peak of more than 370kW. All cell parameters including temperature, voltage and charged capacity were monitored throughout, with the battery pack never exceeding the target operating temperature set by engineers of both teams.

 

The demo showcases StoreDot’s ‘drop-in’ ability to be integrated in an existing car model. It also paves the way to extreme fast charging a car using available charging infrastructure, rather than using proprietary chargers.

 

This world first demonstration featuring a 10-minute charge with silicon-dominant battery cells in an electric vehicle showcased unprecedented charging speeds that will eliminate consumer charging anxiety, a major obstacle to widespread EV adoption.

 

A key advantage of the silicon-based anode technology is the ability to continue pushing both energy density and charging rate boundaries for several more battery generations. In contrast, conventional graphite anodes are already approaching their theoretical performance limits, restricting further advancements.

 

The breakthrough was enabled by StoreDot’s advanced XFC battery cells and represents another major milestone on the company’s path toward commercialization, proving the maturity, stability, and durability of its game-changing technology, while paving the way for an industry-wide XFC battery adoption.
