Abstract

The invention provides a battery core manufacturing method and a battery, and relates to the technical field of batteries. The battery core manufacturing method comprises the following steps: coatinga first pole piece between two diaphragm pieces to form a coating body; folding the coating body for multiple times in a reciprocating manner to form a plurality of clamping grooves; and accommodatinga second pole piece in the clamping groove every time after the coating body is folded, and pressing the coating body and the clamping groove, wherein the first pole piece is a positive pole piece having a positive pole lug, and the second pole piece is a negative pole piece having a negative pole lug; or, the first pole piece is the negative pole piece having the negative pole piece, the secondpole piece is the positive pole piece having the positive pole lug. By adoption of the battery core manufacturing method, a higher volume specific capacity can be provided to improve the own energy density of the battery, meanwhile, the production process is relatively simple, and the production cost can be reduced.

Description

technical field [0001] The present disclosure relates to the field of battery technology, and in particular, to a method for manufacturing a battery cell and a battery. Background technique [0002] In the current social development, there are two trends in improving the performance of power batteries. One is to increase the energy density of the power battery itself, and the other is to save the space occupied by the power battery. [0003] The existing battery manufacturing process either has the problem of low volume-specific capacity, low energy density of the battery itself, or has problems such as complicated procedures and abnormal burrs on the electrode sheet, resulting in losses. Contents of the invention [0004] The purpose of the present disclosure includes providing a method for manufacturing a battery cell, which can provide a higher volume specific capacity to increase the energy density of the battery itself, and at the same time, the production process is ...
