Abstract

The invention relates to battery cell manufacturing equipment and a method thereof. The battery cell manufacturing equipment is used for manufacturing a battery cell, the battery cell comprises a first pole piece, a second pole piece and a diaphragm, the battery cell is provided with a winding starting section located on the inner side, and the battery cell manufacturing equipment comprises a winding needle configured to wind the first pole piece, the second pole piece and the diaphragm to form the battery cell; and the discharging assembly is configured to take down the battery cell from thewinding needle, the discharging assembly comprises an inner side heating needle, and the inner side heating needle is configured to abut against and heat the winding starting section, so at least oneof the first pole piece and the second pole piece of the winding starting section is thermally compounded with the diaphragm. The battery cell manufacturing equipment provided by the invention aims tosolve a problem of lithium precipitation in the inner ring part of the battery cell.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to a battery manufacturing equipment and method thereof. Background technique [0002] In the battery production process, it is necessary to use winding equipment to wind the pole pieces and separators into battery cells. In the initial step of winding, the winding needle can pre-wind a certain number of layers of separator, and then send the pole piece to the winding needle, and finally make the pole piece and separator be wound together by the winding needle to form a battery core. After being wound and pre-pressed and shaped, the battery core has a flat structure. However, during the use of the battery core after being wound and pre-pressed, lithium is deposited in the inner ring, which affects the safety of the battery core. Contents of the invention [0003] The present application provides a cell manufacturing equipment and method thereof, aiming to solve the p...
