StoreDot, which develops extreme fast charging (XFC) battery technology for electric vehicles (EVs), and Polestar, the Swedish electric performance car brand, recently demonstrated a Polestar 5 equipped with StoreDot’s XFC cells, which achieved a particularly quick charging feat.
The 77kWh battery pack charged from 10% to 80% in under 10 minutes, powered by StoreDot’s XFC high-energy silicon-dominant battery cells.
Throughout the demonstration, the vehicle maintained a consistent charge rate exceeding 310kW, peaking at more than 370kW. StoreDot says the battery pack did not overheat, which reportedly ensures stable performance throughout the process.
The EV aims to address consumer charging anxiety with even faster charging speeds.
Thomas Ingenlath, CEO of Polestar, said, “By eliminating charging times that were previously an obstacle, StoreDot’s XFC battery cells combined with our 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.”
Using silicon-based anode technology, according to StoreDot, has advantages for both energy density and charging rates over conventional graphite anodes, which the company suggests are already approaching their theoretical performance limits
Dr Doron Myersdorf, CEO of StoreDot, said, “We’re happy to see that 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. Drivers can now truly travel long distances with the same freedom and convenience as traditional petrol-powered vehicles.”
