Cylindrical lithium ion battery with protection mechanism

Abstract

The invention discloses a cylindrical lithium ion battery with a protection mechanism, the cylindrical lithium ion battery comprises a top plate, a lithium ion battery body, a protection shell and a bottom plate, the top of the lithium ion battery body is provided with a battery cathode joint, and the bottom of the lithium ion battery body is provided with a battery anode joint. According to the invention, by installing the protection shell, a first assembly sheet and a second assembly sheet, when the battery structure is actually used, on one hand, a user can utilize the second assembly sheet adhered to the top and the bottom of the protective shell to cooperate with the effect of a second threaded installation hole to vertically install the battery structure in a proper case; and on the other hand, the user can utilize the four first assembly sheets bonded on one side of the protection shell to be matched with the action of the first threaded mounting holes to mount the battery structure in a proper case in a flat state, so that the battery structure realizes various assembly modes and is convenient to mount.

Description

technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to a cylindrical lithium ion battery with a protection mechanism. Background technique [0002] Lithium-ion batteries are popular with consumers because of their long cycle life, good low-temperature discharge performance, strong charge retention ability, strong continuation ability, and environmental protection. They are especially widely used in electric vehicles. However, the current lithium-ion batteries still have the problems of no protective mechanism, poor protection effect, single installation structure, difficult assembly, poor heat conduction effect, and serious heat loss in actual use, which leads to poor use effect of the battery structure. Contents of the invention [0003] The purpose of the present invention is to provide a cylindrical lithium-ion battery with a protective mechanism to solve the problems of no protective mechanism, poor protection eff...
