In an exciting development for the electric automotive industry, StoreDot and Polestar have demonstrated battery technology that promises to revolutionize the electric vehicle ownership experience. The recent demonstration event revealed the ability to charge an electric vehicle from 10% to 80% in just 10 minutes, using ultra-fast charging silicon battery cells.
Technology Development
The demonstration used a Polestar 5 prototype, equipped with a 77 kWh battery pack using StoreDot’s XFC (Extreme Fast Charging) cells. These cells, which are predominantly silicon and have a high energy density of 300 Wh/kg, made it possible to maintain a constant charging rate of more than 310 kW throughout the testing process, reaching peaks of more than 370 kW.
The success of this test not only highlights the charging speed, but also the ability to integrate StoreDot’s XFC technology into existing car models, making use of available charging infrastructure without the need for proprietary chargers.
Advantages and benefits
The main advantage of StoreDot’s silicon anode cells lies in their potential to continue expanding the limits of energy density and charging rate. Unlike conventional graphite anodes, which are reaching their theoretical performance limits, StoreDot’s silicon design offers a critical path to sustained innovations in ultra-fast charging.
Impact
This technology not only promises to eliminate “charging anxiety,” a significant barrier to EV adoption, but also improves convenience for drivers, allowing them to add approximately 200 miles of range in less than 10 minutes. This capability compares favorably to gasoline-powered vehicles in terms of freedom and convenience for long trips.
Future Developments
According to Dr. Doron Myersdorf, CEO of StoreDot, this demonstration marks an important milestone on the path to commercialization of XFC cells. With future plans to deliver a range of 160 kilometers with just 5 minutes of charging this year, and reducing this time even further by 2026 and 2028, StoreDot is in a promising position to lead the adoption of XFC batteries at an industrial level.
Thomas Ingenlath, CEO of Polestar, also highlighted how this innovation redefines consumer expectations and accelerates mass adoption of electric vehicles by making ownership a seamless experience for the mass market.
