Chinese researchers have developed an ultra-low-temperature lithium battery capable of operating reliably in extreme cold, marking a significant technological advance that could reshape how energy is stored and used in some of the harshest environments on Earth. The innovation was successfully tested in Mohe, Heilongjiang Province—one of China’s coldest regions—where scientists demonstrated stable, plug-and-play performance under conditions that typically cripple conventional batteries.
The testing was carried out by a research team led by Academician Chen Zhongwei of the Dalian Institute of Chemical Physics under the Chinese Academy of Sciences. According to Zhang Meng, associate research fellow and technical leader of the project, the team combined a newly developed battery chemistry with an artificial intelligence-based power management system to overcome a long-standing industrial challenge: the dramatic loss of performance lithium batteries suffer at low temperatures, including reduced activity, shortened range, and even total operational failure.
During field trials conducted at temperatures as low as minus 34 degrees Celsius, the battery retained more than 85 percent of its effective capacity after remaining idle for over eight hours without any external insulation. It subsequently powered an industrial-grade drone through long-endurance flights and multiple mission simulations, demonstrating its practical viability in real-world conditions rather than controlled laboratory settings.
Researchers say the technology could eliminate the long-recognized vulnerability of batteries to freezing conditions, offering reliable energy support for critical operations such as forest fire monitoring, power-line inspections, and emergency communications in high-latitude and high-altitude regions. The ability to maintain performance without bulky warming systems may significantly reduce operational complexity and cost for industries working in extreme climates.
Beyond domestic applications, the development is expected to strengthen China’s energy independence and improve the resilience of scientific and technological equipment deployed in cold environments. Scientists also see potential for the technology to serve as a global solution for countries facing similar challenges, particularly in Arctic research, mountainous infrastructure, and winter logistics.
Looking ahead, the ultra-low-temperature battery and its AI-driven power system could be adapted for consumer electronics, logistics drones, inspection devices, and specialized robots, enabling them to function year-round in regions where seasonal cold has traditionally imposed strict operational limits. The breakthrough signals a step toward energy systems designed not just for efficiency, but for endurance in the planet’s most unforgiving conditions.
