We mainly produce ultra-low temperature lithium batteries for civil use, battery management systems and related supporting materials; We are committed to making up for the gap in the large-scale production of high-performance -50 °C ultra-low temperature special batteries in the market, and to meet the current demand for high-tech batteries in the high-end civil market in specific areas. We also cooperate with scientific research institutions to develop the next generation of solid-state, graphene cryogenic batteries
