According to the financial news on December 28, 2024, the information from the State Intellectual Property Office shows that China Metallurgical Construction Group Corporation has obtained a patent called "A battery assembly with aerogel thermal runaway protection", with the authorization announcement number CN222214332U and the application date of December 2023.


The patent abstract shows that the utility model proposes an aerogel thermal runaway-proof battery assembly, which is suitable for various types of batteries and can be applied to different application scenarios. The system includes an aerogel plate, a battery cell, a phase change material, a liquid cooling plate and an outer frame. The present invention realizes the optimal combination of multiple thermal management solutions by comprehensively using aerogel insulation, thermal energy storage, phase change materials, heat dissipation fins and liquid cooling, thereby improving the safety and performance stability of the battery system. Among them, a heat-insulating aerogel material is set around the battery to prevent the heat generated inside the battery from being transferred to the surrounding battery cells. The aerogel plate adopts a three-layer composite structure of organic layer-aerogel-organic layer to improve the adhesion performance of the aerogel plate and the phase change material. In addition, the battery is cooled or preheated by delivering cold or warm water through the liquid cooling plate to further improve the thermal management effect. It has strong thermal control ability, high safety, good performance stability and compact structure.
