However, in the prior art, the lithium-ion battery adopts the conventional battery packaging process, such as the ultrasonic welding packaging process, and the size of the packaged battery is too large, which cannot meet the requirements of the current digital products for the small size and large capacity of the battery.
[0003] refer to figure 2 , the existing battery is divided into three parts: the battery cell, the battery protection board and the shell. The core is packaged in the shell. In the battery with the same volume, this packaging structure occupies a large volume occupied by the battery protection board and the volume occupied by the battery cell is small, which is not conducive to the development of large-capacity batteries.

Abstract
The present invention provides a battery core and battery protection package structure. The structure comprises a battery core, a battery protection board and a housing. The battery protection board is vertically installed at the side end of the battery core, the battery protection board comprises a battery protection board hard board and a battery protection board soft board, the battery protection board hard board is vertically installed at the side end of the battery core, the battery protection board soft board is vertically arranged at one side, far away from the battery core, of the battery protection board hard board, the battery core, the battery protection board hard board and the part of the battery protection board soft board are installed in the housing, the battery protectionboard soft board arranged in the housing is fixedly connected with the battery protection board hard board, and the other part of the battery protection board soft board passes through the housing. The novel package process of the battery core and the battery protection board allows the volume occupied by the battery protection board to be reduced, and the whole volume of the battery is reduced inthe same condition.
Description
technical field [0001] The invention relates to the field of batteries, in particular to a package structure of a battery cell and a battery protection plate. Background technique [0002] With the continuous emergence of digital products with super large screens and super entertainment functions, the energy density of digital batteries is required to be higher and higher. Lithium-ion batteries are favored by consumers due to their high capacity density and good safety performance. However, in the prior art, lithium-ion batteries adopt conventional battery packaging technology, such as ultrasonic welding packaging technology, and the size of the packaged battery is too large, which cannot meet the requirements of current digital products for small battery size and large capacity. [0003] refer to figure 2 , the existing battery is divided into three parts: the battery cell, the battery protection board and the shell. The core is packaged in the shell. In the battery of th...
