At the Polestar Day event in California, Polestar announced its collaboration with Israeli battery startup StoreDot to test an electric car prototype equipped with StoreDot’s extreme fast charging (XFC) cells. The technology, known as “100-in-5,” promises to add 100 miles of range in just five minutes of charging, potentially revolutionizing the electric vehicle (EV) ownership experience.
Polestar, an investor in StoreDot along with Volvo Cars, Mercedes-Benz, and VinFast, is exploring the integration of the “100-in-5” cells into a production-level solution. The companies are working on an advanced engineering project to demonstrate how XFC battery cells can be fitted to an existing platform, showcasing what a future production-level solution might look like.
The announcement was made at the Los Angeles event, featuring a live demonstration of StoreDot’s “100-in-5” XFC cell charging alongside a prototype of a Polestar 5 battery module. The collaboration includes key integration work, focusing on engineering design and cooling of the battery pack.
Dr. Doron Myersdorf, CEO of StoreDot, expressed pride in the collaboration, stating, “This is a huge step for StoreDot and a strong endorsement that our ground-breaking technology is readying for mass production.” He acknowledged the work ahead to fully integrate their systems into a production car but emphasized the teams’ engagement and commitment to demonstrating results in the coming months.
Polestar’s CEO, Thomas Ingenlath, highlighted the company’s partnership with StoreDot in applying their advanced technology in proof-of-concept Polestar cars. He stated, “StoreDot’s pioneering extreme fast charging batteries, combined with our upcoming top-of-the-line electric powertrain, can revolutionize the ownership experience for EV owners with the ability to recharge in minutes.”
StoreDot is renowned for its pouch cells featuring silicon-dominant chemistries, enabling EVs to charge at exceptionally high speeds without battery degradation. Recent tests by the Israeli startup indicated that its battery prototype withstood 1,000 consecutive extreme fast charging tests without degradation, showcasing the technology’s robustness.
StoreDot’s “100inX” technology roadmap outlines three generations of technologies, with XFC cells expected to accept 100 miles of charge in five minutes by 2024. The company aims to further reduce charging time to 3 minutes by 2028 and 2 minutes by 2032.
Independent battery lab Shmuel De-Leon Energy validated the commercial viability of StoreDot’s pouch cells in tests conducted last year. If successful, the collaboration between Polestar and StoreDot could pave the way for some of the quickest-recharging EVs on the road, advancing the landscape of electric mobility.
