[0025] The temperature sensing component 20 automatically changes color as the battery temperature changes, so that the temperature change inside the battery shell can be judged according to the color of the color-changing block 22, so that factory inspectors or customers can judge the battery temperature and distinguish between genuine and defective products by the specific color of the color-changing block 22.
[0026] The color changing block 22 is made of a reversible color changing material, ensuring that the color changing block 22 can be reused.
[0027] The number of the color-changing blocks 22 can be set according to actual needs by providing the same number of mounting slots 21 . In this embodiment, the number of the color-changing blocks 22 is set to two.
[0028] The color-changing material of the color-changing block 22 is prepared from an electron transfer type organic compound system. Electron transfer type organic compounds are a type of organic color-producing system with a special chemical structure. At a specific temperature, the molecular structure of the organic matter changes due to electron transfer, thereby achieving a reversible color change. It includes a temperature-sensitive color powder and an external transparent protective layer, and the transparent protective layer includes transparent materials such as PE, PP, PS and AS, and is formed by mixing one or more temperature-sensitive color-changing powder microcapsules with a substrate and processing by an injection molding machine.

[0032] It also includes an explosion-proof component 30, which includes an explosion-proof port stamped on one of the side walls of the shell 11, a reinforcement member 31 is arranged inside the explosion-proof port, and an explosion-proof plate 32 is arranged outside the reinforcement member 31 in the explosion-proof port to cover the explosion-proof port, and the reinforcement member 31 and the explosion-proof plate 32 are fixedly connected to the inner wall of the explosion-proof port.
[0033] The explosion-proof component 30 achieves the function of relieving pressure when the internal pressure of the battery is too high, explosion or leakage occurs.
[0034] The reinforcement member 31 is formed by connecting a plurality of reinforcement ribs to each other, and forms a shape such as a tic-tac-toe shape, a cross shape, a ring shape, etc.
[0035] The reinforcement 31 supports the explosion-proof opening, thereby improving the mechanical strength of the explosion-proof opening, while improving the torsion resistance, vibration resistance and impact resistance, reducing the possibility of deformation or even rupture of the explosion-proof opening when the shell 11 is subjected to external force, thereby reducing the possibility of electrolyte leakage inside the battery.
