Chinese Lab’s Aluminium‑based EV Cell Passes -25°C Road Test, Charging to 90% in 20 Minutes
A Chinese Academy of Sciences institute reports an aluminium‑based lithium‑ion battery that, when fitted to a production EV, sustained over 92% discharge efficiency and charged to 90% in 20 minutes after a 24‑hour soak at −25°C. The result, if validated and scalable, could reduce winter range loss and simplify thermal management, widening EV usability in cold markets.
