Abstract

The invention discloses a battery module which comprises a battery core, a soft shell and a bearing seat, wherein the battery core is provided with a body and an electrode slice which extends outwards from the body, the soft shell is provided with an upper cover plate and a lower cover plate, the upper cover plate and the lower cover plate are matched with each other to cover the battery core in a matching mode and are provided for the electrode slice to penetrate through, each of the upper cover plate and a lower cover plate is provided with an upper adhesion part and a lower adhesion part which are adhered with each other, the bearing seat is used for arranging the soft shell, the soft shell is also provided with an extension part which is formed in such a way that one of the upper adhesion part and the lower adhesion part extends towards the bearing seat, and the extension part is provided with an adhesion layer which is adhered to the bearing seat in a hot pressing mode, therefore, the soft shell and the bearing seat can be stably connected.

Description

Technical field [0001] The present invention relates to a battery module, in particular to a battery module used in an electronic device. Background technique [0002] Secondary batteries have been widely used in general portable electronic devices, such as mobile phones, digital cameras, notebook computers and other devices. However, as the size of these portable electronic devices shrinks and the use time increases, the power of the secondary batteries used in these devices increases. In this way, the secondary batteries will generate more waste heat, so improving the heat dissipation of the secondary batteries becomes It is one of the topics that are being researched by various industry players. [0003] Please refer to figure 1 Shown is a three-dimensional exploded view of the existing secondary battery fixing structure. The existing secondary battery 1a includes a battery cell 11a, a flexible casing 12a, a carrier 20a, and a plurality of double-sided adhesive tapes 30a. The ...
