Polestar 5 fitted with StoreDot’s XFC cells showcased |Charges from 10% to 80% in 10 minutes

Herzliya, Israel, 29th April 2024; StoreDot, an extremely fast charging (XFC) battery technology company, and Polestar, the Swedish electric car brand, have demonstrated battery technology that charges an electric vehicle in just 10 minutes.

In the demo video (seen here) the companies successfully charged a 77kWh battery pack powered by StoreDot’s 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 the engineers of both teams. The demo showcases StoreDot’s ‘drop-in’ ability to be integrated into an existing car model. It also paves the way for extremely fast charging of a car using available charging infrastructure rather than proprietary chargers.  

A company statement said – 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. StoreDot’s silicon design provides a crucial pathway to sustained innovation in areas like extreme fast charging.

Dr Doron Myersdorf, CEO of StoreDot:

“We are very excited to share this impressive achievement today and are proud to be on this journey with Polestar, a leading car brand who envisions high performance cars with a sustainable future. We’re happy to see our partner is among the first EV car makers to acknowledge that XFC is now a necessary standard to make vast EV adoption a reality. With our extreme fast charging technology, you can add 200 miles in under 10 minutes. This breakthrough revolutionizes EV ownership experience by eradicating the barrier of range and charging anxiety once and for all.”

Thomas Ingenlath, CEO of Polestar:

“By eliminating charging times that were previously an obstacle, StoreDot’s XFC battery cells combined with our cutting-edge product development and battery engineering have unlocked new frontiers for electric mobility. This technology will reshape consumer expectations and accelerate mass EV adoption by making EV ownership a seamless experience for the mass market.”

StoreDot’s path to commercialise its fast charging battery technology:

In January 2024, StoreDot announced its anticipated milestones for 2024, one of which was today’s demonstration. Other upcoming milestones include shipping prismatic B-samples to OEMs and signing strategic manufacturing agreements. StoreDot said it remains on track with the production-readiness of its XFC cells that deliver 100 miles charged in 5 minutes this year. The company aims to deliver 100 miles charged in 4 minutes in 2026 and 100 miles charged in 3 minutes by 2028. StoreDot’s strategic investors and partners include BP, Daimler, VinFast, Volvo Cars, Polestar, Ola Electric, Samsung, TDK, and its manufacturing partner EVE Energy.
