Herzliya, Israel- StoreDot and Polestar, have pioneered battery technology that charges an electric vehicle in just 10 minutes.
In the demo video (Please see the embedded YouTube link below), the companies successfully 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. The battery pack never exceeded 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 featured a 10-minute charge with silicon-dominant battery cells in an electric vehicle. It showcased unprecedented charging speeds that will eliminate consumer charging anxiety, a major obstacle to widespread EV adoption.
The key advantage of silicon-based anode technology is its ability to continue pushing both energy density and charging rate boundaries. This progress can extend 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.
StoreDot’s advanced XFC battery cells enabled the breakthrough. It represents another major milestone on the company’s path toward commercialization. It proves the maturity, stability, and durability of its game-changing technology, while paving the way for an industry-wide XFC battery adoption.
Dr. Doron Myersdorf, CEO of StoreDot:
“We are very excited to share this impressive achievement today. We’re honored to journey alongside Polestar, a pioneering automotive brand committed to high-performance cars and 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. Moreover, drivers can now truly travel long distances with the same freedom and convenience as traditional petrol-powered vehicles.”
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. The technology’s aim is to reshape consumer expectations and expedite mass EV adoption by ensuring seamless EV ownership for all.”
In January StoreDot announced its anticipated milestones for 2024, one of which was today’s demonstration. Moreover, other upcoming milestones include shipping prismatic B-samples to OEMs and signing strategic manufacturing agreements.
This year, StoreDot stays steadfast, ensuring production-readiness for its XFC cells, enabling 100 miles charge in just 5 minutes. The company aims to deliver 100 miles charged in 4 minutes in 2026 and 100 miles charged in 3 minutes by 2028.
