Researchers from China's Dalian Institute of Chemical Physics have introduced a groundbreaking EV battery technology that outperforms traditional lithium-ion packs in freezing conditions. Known as the 'liquid-solid' battery, it can retain over 85% capacity after eight hours at -34°C (-29°F), offering promising results in initial tests involving industrial-grade drones.

A team from the Chinese Academy of Sciences (CAS) has also made strides in enhancing EV batteries for sub-zero temperatures. Researchers tested an aluminum-based wide-temperature lithium-ion battery in a Geely EX5 EV, achieving impressive results. The battery boasts over 92% discharge efficiency at -25°C (-13°F) and can charge up to 90% in just 20 minutes under extreme cold.

The aluminum-anode design of this new battery tackles the longstanding issue of reduced performance in low temperatures experienced by traditional lithium-ion batteries in EVs. By expanding the operating temperature range and effectively managing heat during rapid charging, this innovation eliminates the need for complex insulation, potentially alleviating winter range concerns and speeding up charging for cold climate drivers.

Chinese battery giants like BYD and CATL have been at the forefront of ultra-fast charging technology, aiming to boost range significantly within minutes under optimal conditions. However, maintaining such performance in freezing temperatures has proven challenging. The introduction of the aluminum-based battery could provide a significant advantage by combining rapid charging capabilities with enhanced cold-weather efficiency, marking a pivotal advancement in EV battery technology that may bridge the gap between electric and ICE vehicles across all climates.
