StoreDot's XFC 4695 Cells Ready for Commercialization, Shipping to Global EV OEMs

StoreDot, with its partner Kumyang, moves from development to commercialization, shipping volume samples of its validated XFC 4695 cells to OEMs.

HERZELIYA, ISRAEL, September 2, 2025 /EINPresswire.com/ -- StoreDot, the pioneer of extreme fast charging (XFC) battery technology, today announced the successful production of a large-scale batch of 4695 cylindrical cells in collaboration with its key partner, Kumyang. This achievement marks a significant milestone in the mass production of XFC technology, signaling that the company is on track to meet the long-awaited demand from electric vehicle (EV) manufacturers.

The successful production run validated that all previously published specifications were met and even exceeded, demonstrating the scalability and readiness of StoreDot's XFC technology for high-volume manufacturing. For EV OEMs who have been closely monitoring the development of this game-changing technology, this is the pivotal moment they have been waiting for. The 4695 cells, produced at Kumyang's facility in Korea, achieved the extreme fast charging speeds and energy density targets that StoreDot had set out to prove, clearing the path for commercial adoption.
This achievement validates StoreDot's innovative XFC technology on a production scale, showing it can be integrated into existing manufacturing lines to produce high-performance cells that meet the stringent demands of the automotive industry. The 4695 format is a key part of the global transition to electric vehicles (EVs), and this milestone puts StoreDot at the forefront of this evolution.
