On September 4, 2026, Xiaomi, together with Zhongchuang Xianhang and Xinwangda, launched the new “Longjia” battery. Li Xiaoshuang, vice president of Xiaomi Automobile, stated that Xiaomi will be responsible for the entire development process of this battery, deeply participating in the research and development of the battery cells and leading the design of the battery pack. At the cell level, Xiaomi has carefully selected core materials such as electrodes, electrolytes, and separators to optimize the electrochemical system and manufacturing processes, resulting in a cycle life far exceeding national standards and lower long-term degradation. In terms of safety performance, the Longjia battery meets multiple national standards: it prevents thermal runaway at high temperatures of 55°C without heat spread; it is equipped with millisecond-level mechanical switches and multiple redundant insulation protections for electrical safety; it has a data collection frequency 10 times higher than national standards and全天候 cloud-based AI proactive inspections; and its functional safety features use the highest ASIL-D level design, combined with self-developed BMS software to achieve millisecond-level fault response.
Li Xiaoshuang, vice president of Xiaomi Auto, said that Xiaomi will be responsible for the entire process of Longjia batteries, participating in battery cell development and leading battery pack design. This product is developed in collaboration with Zhongchuang Innovation Aerospace and Sunwoda. Xiaomi will delve into the underlying aspects of battery cells to ensure their cycle life and safety standards. Together with suppliers, Xiaomi will research and develop electrochemical systems, battery cell designs, and manufacturing processes. At the same time, Xiaomi will control safety capabilities and performance from a systematic level, leading the development of the mechanical structure of the battery pack, electronic and electrical architectures, vehicle thermal management strategies, BMS requirements, and software solutions.
Xiaomi has released the new Longjia battery. Li Xiaoshuang, vice president of Xiaomi Auto, explained that the cycle life of the Longjia battery cells far exceeds national standards. The battery’s electrodes, electrolyte, and separator are carefully selected, and its core design and manufacturing processes have been optimized to achieve lower long-term degradation and better safety. Additionally, the Longjia battery meets multiple safety standards beyond national requirements: in terms of thermal safety, it prevents heat spread when exposed to 55°C temperatures; in terms of cell cycle life, the carefully selected electrodes, electrolyte, and separator, along with optimized core design and processes, result in lower long-term degradation and better safety; in terms of electrical safety, it features millisecond-level mechanical switches and comprehensive redundant insulation protection, with electrical safety distances far exceeding national standards; in terms of big data security, it has a 10-fold higher collection frequency and 3-fold higher collection volume than national standards, providing 24-hour vehicle-cloud collaborative safety alerts and全天候 cloud-based AI proactive inspections; in terms of functional safety, it features the highest ASIL-D level design in the industry, uses self-developed BMS battery management software, and has multi-level battery protection software and hardware strategies, enabling millisecond-level safety fault response capabilities.
