Beijing (TDI): Chinese researchers have developed an ultra-low-temperature lithium battery capable of operating reliably in extreme cold, paving the way for uninterrupted energy supply to drones, robots, and other devices in harsh environments.
On-site tests in Mohe, Heilongjiang Province, one of China’s coldest regions, showed the battery maintaining more than 85% of its capacity after eight hours at -34 °C, without any external insulation.
The breakthrough comes from a team led by Academician Chen Zhongwei at the Dalian Institute of Chemical Physics. Zhang Meng, associate research fellow and technical lead for the project, highlighted that the battery, combined with a proprietary AI-based power management system, addresses a longstanding industrial challenge: conventional lithium batteries lose efficiency, range, or even fail entirely in extreme cold.

During testing, the battery successfully powered an industrial-grade drone for long-endurance flights and multiple mission simulations.
The technology is expected to support critical operations such as forest fire monitoring, high-altitude power line inspections, and emergency communications in both China and other frigid regions globally.
Beyond drones, the ultra-low-temperature battery and AI management system could be applied to 3C electronic products, logistics and inspection drones, special-purpose robots, and other outdoor equipment, enabling them to operate without seasonal or geographic restrictions.

Researchers emphasize that the technology will not only improve the reliability of scientific and industrial equipment in extreme conditions but also strengthen China’s energy independence. Its deployment could offer practical solutions for countries worldwide that face challenges in powering devices in freezing environments.
