Charging
the EV lifestyle
FastRefill like fuel. Drive like electric. 10→80% in ten minutes on the chargers that already exist.
World's first 10-minute EV charge with Si-dominant cells
April 2024, live, on a full-size Polestar 5 verification prototype: 10→80% in ten minutes on a standard 350 kW charger. Not a lab cell. A vehicle.
Since then, seven global OEMs have independently tested XFC cells against their own safety and performance programs — and competing cells. StoreDot's cells passed, outperformed, and are now under commercial licensing agreements.

from cell to pack
Chemistry alone isn't enough. The battery must fit each automaker's vision — and manage the heat of extreme charging at vehicle level.
Fewer parts, less weight
Cells connect directly into the pack, simplifying manufacturing and reducing volume while protecting against vibration, impact and thermal expansion.
Built for XFC heat
The chassis doubles as heat sink during ten-minute charging — StoreDot's fast-charge and thermal-optimization experience shapes the pack.
