StoreDot and Polestar Introduce 10-Minute Fast Charging with Silicon Anode Batteries

April 29, 2024

StoreDot and Polestar introduced silicon anode batteries capable of charging EVs in under 10 minutes.
Their “drop-in” technology seamlessly integrates with existing car models and charging infrastructure.
StoreDot’s roadmap targets charging 100 miles in 5 minutes this year, 4 minutes in 2026, and 3 minutes by 2028.

StoreDot and Polestar have recently shattered the boundaries of electric vehicle (EV) battery technology, introducing silicon anode batteries capable of charging an EV in under 10 minutes. This milestone is a step forward in widespread EV adoption, addressing two key barriers: range anxiety and charging worries.

In this recent demonstration video, StoreDot and Polestar showcased how the breakthrough extreme fast charging (XFC) battery technology charged a 77kWh battery pack from 10% to 80% in under 10 minutes. The battery, which powers a fully drivable Polestar 5 prototype, consistently charged at a rate of over 310kW, peaking at over 370kW. StoreDot’s batteries feature silicon anode cells, delivering high energy density (300Wh/kg), which were essential to this success.

The demonstration highlights how StoreDot’s “drop-in” technology, featuring silicone battery cells, integrates seamlessly with existing car models. It also shows how this XFC technology can be used with current charging infrastructure, eliminating the need for proprietary chargers. This breakthrough significantly decreases worries about charging for consumers, a big barrier to more people choosing EVs.

Dr. Doron Myersdorf, CEO of StoreDot, spotlighted the significance of this achievement: “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. Drivers can now truly travel long distances with the same freedom and convenience as traditional petrol-powered vehicles.”

Thomas Ingenlath, CEO of Polestar, added, “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 ‘100inX’ product roadmap is designed to steadily deliver improvements over the upcoming years. The goal is to achieve 100 miles of range charged in 5 minutes this year, 4 minutes in 2026, and 3 minutes by 2028. These advancements will change how EV owners perceive charging, making it quicker and more convenient than ever before.

The silicon anode battery technology used by StoreDot plays a crucial role in this evolution, allowing further advancements in energy density and charging rates. This stands in stark contrast to conventional graphite anodes, which are nearing their performance limits.

StoreDot’s progress reflects its path toward commercialization and further reinforces its position as an industry leader. With its advanced XFC silicon anode battery cells, the company introduces technology that’s not only advanced but also reliable and durable, playing a crucial role in encouraging widespread adoption across the industry.
