[0002] At present, lead-acid batteries are mostly used as energy storage batteries. Lead-acid batteries have disadvantages such as large volume, low energy density ratio, less cycle times, and no environmental protection. Lithium battery energy storage is gradually accepted by the market; with the development of industry, lithium batteries There will be more and more application scenarios, such as emergency power supply, 5G communication, home energy storage, etc.; the existing modular cylindrical cells adopt a layered structure, which has the advantages of simple structure and safety

[0003] However, the current lithium battery and the matching box of the lithium battery have certain deficiencies. For example, the module structure of the battery pack is a stacked structure, and the heat dissipation capability is poor. , Turning on the water-cooling structure in the case of unnecessary heat dissipation will increase the loss of the battery. At the same time, the heating structure that maintains the operating temperature of the battery must also work, thereby greatly increasing the loss of the battery
