Domestic Aluminum-Based Battery Passes Extreme Cold Test in Heihe: Over 92% Discharge Efficiency at -25°C

The Institute of Carbon Neutrality at the Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, recently announced that its self-developed aluminum-based lithium-ion battery—capable of operating across an ultra-wide temperature range—has successfully completed full-vehicle testing under extreme cold conditions in Heihe, Heilongjiang Province. The battery was installed for the first time in a mass-produced all-electric vehicle from a leading Chinese new energy automaker. After being soaked in a -25°C environment for over 24 hours, the vehicle demonstrated a discharge efficiency exceeding 92% under urban driving conditions and supported low-temperature fast charging—reaching 90% state of charge in just 20 minutes. This breakthrough marks significant progress in China's efforts to enhance electric vehicle range and charging performance in frigid regions.
