Sodium‑Ion EV Battery Breakthrough: 11‑Minute Charge, 450 km Range
New Sodium‑Ion Battery Sets Record for Fast Charging and Long Range
BAIC has unveiled a prototype sodium‑ion electric‑vehicle battery that delivers an impressive 170 Wh/kg energy density, a 450 km (CLTC) driving range, and can be charged from 0 % to 80 % in just 11 minutes at a 4C rate. The breakthrough demonstrates that sodium‑ion technology can compete with lithium‑ion systems while offering lower material costs and broader temperature tolerance.
The battery’s performance was highlighted in a recent test where a full charge was achieved in under a quarter of an hour, providing a practical solution for drivers who need rapid top‑ups on long journeys. In addition to fast charging, the cells maintain stable operation across a wide temperature range, addressing one of the key challenges for sodium‑ion chemistries.
Industry analysts see this development as a catalyst for wider adoption of sodium‑ion batteries, especially in markets where cost‑effectiveness and resource availability are critical. While lithium‑ion remains dominant, the lower cost of sodium and the ability to source it abundantly could drive a shift toward more sustainable, affordable EV powertrains.
