Abstract

A battery structure includes a casing, a battery core module, a heat shrink film, a first buffer layer, a second buffer layer and a glue layer. The casing includes an upper cover, a lower cover and a side plate connecting the upper cover and the lower cover. The upper cover, lower cover and side plates are surrounded by an accommodating cavity, and the lower cover is provided with a pressure relief groove communicating with the accommodating cavity. The battery core module is contained in the accommodation cavity; the heat shrinkable film covers the battery core module, and the heat shrinkable film is provided with a first through hole corresponding to the pressure relief groove. A first buffer layer is located between the heat shrink film and the lower cover, and the first buffer layer is provided with a second through hole, and the second through hole connects the first through hole and the pressure relief groove. A second buffer layer surrounds the battery core module and is located between the heat shrink film and the side plate. A glue layer is poured between the shell and the second buffer layer. The above-mentioned battery structure facilitates disassembly and exhaust, thereby extending service life.

Description

Technical field [0001] This application relates to a battery structure. Background technique [0002] Batteries have the advantages of large specific energy, high working voltage, low self-discharge rate, small size, and light weight, and are widely used in daily life. When the battery module is packaged to form a battery, the inside of the casing is filled with glue, and the battery module and the casing are bonded through the glue layer to fix the battery module. However, because the battery core is wrapped in a layer of glue, the gas produced by the battery core cannot be removed in time, which easily causes the battery to deform. Moreover, when the battery is disassembled, the glue layer adheres to the battery module, making it easy to remove the glue layer. Damage the battery module. Contents of the invention [0003] In view of the above situation, it is necessary to provide a battery structure that is beneficial to extending the service life. [0004] A battery s...
