2 min readNov 9, 2023

In Los Angeles today, Polestar announced exploration of StoreDot’s 100-in-5 XFC battery cell technology, which follows the EV maker’s agreement with SK On for Polestar 5 batteries, a strengthened business plan, and the start of production of the important Polestar 4.
At today’s Polestar Day event in Los Angeles, a new collaboration was announced with EV battery innovator StoreDot to explore and demonstrate the viability of production-level extreme fast charging (XFC) battery cell technology when applied to an existing platform.

StoreDot’s 100-in-5 XFC battery cell technology, which is designed to deliver 100 mi of range after just 5 min of charging with no battery degradation, is already in development with Polestar, which is also a strategic investor in StoreDot. The goal of the partnership is to demonstrate StoreDot’s production-ready XFC technology at full scale in a Polestar 5 prototype EV in 2024. The detailed collaboration includes key integrations such as the engineering design and cooling.

“This is a huge step for StoreDot and a strong endorsement that our groundbreaking technology is readying for mass production,” said Dr. Doron Myersdorf, CEO of StoreDot. “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, drivable prototype. We still have lots of work to do to fully integrate our systems into a production car, but our teams are already fully engaged.”

The partners will be demonstrating those results in the coming months.
