Abstract

The invention discloses a manufacturing method of a roll core and a button battery. The method comprises the following steps: connecting a first tab with a first pole piece; connecting a second tab with a second pole piece; a first pole piece, a second pole piece and a diaphragm are stacked, and the diaphragm forms isolation between the first pole piece and the second pole piece; and winding the first pole piece, the second pole piece and the diaphragm to form a winding structure with a through hole in the middle. One technical effect of the embodiment of the invention is that after the first tab is connected with the first pole piece and the second tab is connected with the second pole piece, the first pole piece, the second pole piece and the diaphragm are wound, so that damage to the winding structure caused by connection of the first tab and the second tab with the winding structure after winding can be avoided; the safety performance of the manufactured roll core is improved, and the problem that the roll core loses efficacy is avoided.

Description

technical field [0001] The present invention relates to the technical field of batteries, and more particularly, to a method for manufacturing a winding core and a button battery. Background technique [0002] Button batteries are widely used because of their small size, large capacity and good consistency. In the related art, in the process of making a button battery, it is necessary to set the tabs on the winding core. In the process of setting the tabs on the winding core, the connection process easily damages the structure of the winding core itself and the connection between the pole pieces. Insulation structure, leading to the problem of core failure. SUMMARY OF THE INVENTION [0003] An object of the present invention is to provide a new technical solution for a winding core and a method for manufacturing a button battery. [0004] According to a first aspect of the present invention, there is provided a method for manufacturing a winding core, the method comprisi...
