Abstract

A disclosed button cell comprises a shell assembly and a cell assembly, the shell assembly comprises a shell, a cover plate and a pole plate, the cover plate is electrically connected with the shell and covers the shell to form a cell cavity, the cover plate is provided with a matching through hole, and the pole plate covers or fills the matching through hole and is arranged on the cover plate in an insulating manner; and the cell assembly comprises a first pole piece and a second pole piece, the first pole piece and the second pole piece are arranged in an insulating manner and are wound to form a roll core structure, the first pole piece is electrically connected with the pole plate, and the second pole piece is electrically connected with the shell or the cover plate. The cover plate is electrically connected with the shell to serve as a shell of one pole, the pole plate serves as a shell of the other pole, the pole plate and the cover plate are in insulation fit to avoid short circuit, the first pole piece is electrically connected with the pole plate, and the second pole piece is electrically connected with the shell or the cover plate to conduct; and compared with a traditional mode that the cover plate and the shell are arranged in an insulated mode, the polar plate is matched with the through hole to achieve reliable insulation matching with the cover plate more easily, and therefore performance and safety of the button cell are guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of button batteries, and more particularly to a button battery. Background technique [0002] Button Cells are often also referred to as a buckle battery refers to a class of batteries similar to a button. The diameter of the button battery is usually relatively larger, and the thickness is relatively thin. The button battery includes a steel case, a top cover, and a battery, and the upper cover is disposed on the steel case to form a cell chamber, and the battery cell assembly is disposed within the battery cell. [0003] Since insulation is required between the upper cover and the steel shell, an insulating ring is typically provided between the upper cover and the steel shell to insulate and seal the edges of the steel shell and the upper cover. However, this structure is easy to make the insulation and sealing effect, so that the upper cover and steel shell are short-circuited to affect the performanc...
