The invention discloses a battery shell structure and a button battery. The battery shell structure comprises an upper cover and a bottom shell; the bottom shell and the upper cover are matched to form a sealed cavity; the sealed cavity is used for installing a battery cell assembly; a first blind groove is formed in the bottom shell; the button battery comprises a battery cell assembly and the battery shell structure, and the battery cell assembly is arranged in the sealed cavity. According to the battery shell structure, the upper cover and the bottom shell can be matched to form the sealedcavity so as to provide the mounting space of the battery cell assembly; the first blind groove is formed in the bottom shell; the wall thickness of the area where the first blind groove is located issmaller than that of other areas due to the first blind groove, so that when the battery fails or is scrapped, the battery can be broken firstly under the action of high-pressure gas, so that a pressure relief opening is formed, and therefore, the explosion of the battery due to incapability of releasing the high-pressure gas is avoided, and safety is guaranteed; the button battery comprises thebattery shell structure, and pressure relief and explosion prevention can be carried out by utilizing the first blind groove, so that the safety is guaranteed.
Description
technical field [0001] The invention relates to the technical field of battery safety, in particular to a battery casing structure and a button battery. Background technique [0002] Button Cell (Button Cell), also commonly known as button battery, refers to a type of battery that looks like a button. Compared with a cylindrical battery, the thickness of a button cell is thinner. Button batteries are widely used in various miniature electronic products due to their small size. [0003] A traditional button battery includes a bottom case, an upper cover and a cell assembly. The bottom case and the upper cover cooperate to form a sealed chamber, and the cell assembly is installed in the sealed chamber. However, when the battery fails or is scrapped, due to the abnormality of the cell components in the sealed cavity, if there is no normal explosion-proof way, the energy in the sealed cavity cannot be released. In this case, it is easy to cause an explosion Even more serious s...
