Shenzhen, September 11 - The team of Professor Chen Zuhuang at Harbin Institute of Technology, Shenzhen（HITSZ）, together with multiple research institutions, has achieved a technological breakthrough in ultra-low-temperature energy storage. The findings were published in Nature Nanotechnology, which also published an expert commentary.

Special operating scenarios such as deep space, deep sea, and polar regions place high demands on the low-temperature performance of energy storage devices, and ordinary energy storage equipment shows significant performance degradation in low-temperature environments. The team optimized material composition and developed a new type of energy storage material. The material can operate stably across a wide temperature range from near absolute zero to room temperature, maintaining energy storage efficiency above 88% and stable performance after repeated charge-discharge cycles, achieving high-density energy storage application under ultra-low-temperature conditions for the first time.

The study further broadens the applicable temperature range of energy storage devices and provides a new solution for powering electronic equipment in extreme environments. HITSZ is the first corresponding institution of the paper. The research was supported by the National Natural Science Foundation of China, the Guangdong Provincial Basic and Applied Basic Research Fund, the Shenzhen Young Outstanding Science and Technology Talent Cultivation Program, and the HIT "0-1 Original Exploration Program."
