StoreDot and Polestar partner for world’s first EV with extreme fast charging battery tech

StoreDot, the pioneer of extreme fast charging (XFC) battery technology for electric vehicles, is collaborating with EV maker Polestar on an advanced engineering project to technically explore and demonstrate how XFC battery cell technology can be applied to an existing platform, and show what a production-level solution could look like.

The announcement was made at this week’s Polestar Day in Los Angeles, California, where StoreDot’s ‘100-in-5’ XFC cell charging was demonstrated, alongside a prototype of a Polestar battery module. 

Following Polestar’s investment in StoreDot and as part of an ongoing strategic partnership, the two companies are now already in advanced collaboration and are working to demonstrate StoreDot’s production-ready XFC technology at full scale in a Polestar 5 prototype vehicle in 2024. The detailed collaboration includes key integrations such as the engineering design and cooling.

Dr Doron Myersdorf, CEO of StoreDot, said: “This is a huge step for StoreDot and a strong endorsement that our ground-breaking technology is readying for mass production. We are extremely pleased and proud that Polestar aims to be the first automotive company to showcase our extreme fast charging battery cells in a full-scale, driveable prototype. Polestar is already a strategic investor in our business, but this really cements and builds on our collaboration. We still have lots of work to do to fully integrate our systems into a production car, but our teams are already fully engaged, and we will be demonstrating those results in the coming months.

“We can’t wait to see this technology in the hands of customers taking advantage of such game-changing charging speeds.”

Thomas Ingenlath, CEO of Polestar, commented: “StoreDot was our first financial investment in another company, and we have been collaborating with them to apply their advanced technology in proof-of-concept Polestar cars. 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 a world leader in silicon-dominant chemistries that are essential for electric vehicles to be able to charge at extremely high speeds. The company has already unveiled its '100inX' strategic technology roadmap, outlining three generations of StoreDot technologies: Silicon dominant XFC, semi-solid state, and post-lithium architecture. This roadmap reiterates the anticipated milestones over the next decade with ‘100-in-5’ targeted for 2024, ‘100-in-3’ for 2028, and ‘100-in-2’ for 2032.

Polestar plans to have a line-up of five performance EVs by 2026 – the Polestar 2 performance fastback launched in 2019, Polestar 3 SUV launched in late 2022, Polestar 4 SUV coupé launching in phases through 2023 and into 2024; Polestar 5, an electric four-door GT and Polestar 6, an electric roadster, are being developed.
