StoreDot, a manufacturer of extreme fast-charging (XFC) battery technology for electric vehicles (EVs), and Polestar, an electric performance car brand, have charged an EV in just 10 minutes.

A 77 kWh battery pack, powered by StoreDot’s XFC high energy (300 Wh/kg) silicon-dominant battery cells, installed in a Polestar 5 prototype, was charged from 10% to 80% in less than 10 minutes.

The vehicle saw a consistent charge rate of over 310 kW for the entire test and a peak of more than 370 kW.

A key advantage of StoreDot’s silicon-based anode technology is the ability to continue pushing energy density and charging rate boundaries. In contrast, conventional graphite anodes are already approaching their theoretical performance limits.

StoreDot has improved the conventional Li-ion battery by innovating and synthesising proprietary organic and inorganic compounds, optimised by AI algorithms.

Dr Doron Myersdorf, CEO of StoreDot, says: “With our extreme, fast-charging technology, you can add 200 miles in under 10 minutes. This breakthrough revolutionises EV ownership experience by eradicating the barrier of range and charging anxiety once and for all. Drivers can truly travel long distances with the same freedom and convenience as traditional, petrol-powered vehicles.”

Thomas Ingenlath, CEO of Polestar, says: “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 remains on track with production-readiness of its XFC cells that deliver 100 miles, charged in five minutes, this year.

The company’s strategic investors and partners include BP, Daimler, VinFast, Volvo Cars, Polestar, Ola Electric, Samsung and TDK, and its manufacturing partner, EVE Energy.
