Abstract

The invention discloses a high-voltage button cell. The high-voltage button cell comprises a negative electrode cover and a positive electrode shell which are matched with each other to form a cell shell, wherein a cavity formed by the negative electrode cover and the positive electrode shell is internally provided with a plurality of battery cells which are connected in series with each other; each battery cell comprises a positive plate and a negative plate; a diaphragm is arranged between the positive plate and the negative plate; the positive plate / the negative plate in each battery cell is electrically connected with the negative plate / the positive plate in another adjacent battery cell; and each battery cell is separated from the other adjacent battery cell which is connected in series through the diaphragm. The series connection in the button cell is directly completed with no need for connection a plurality of battery cells in series to form a battery pack so as to solve the problem of battery core consistence.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a high-voltage button battery and a manufacturing method thereof. Background technique [0002] A button battery, also known as a button battery, refers to a battery that looks like a small button. Because of its small size, it is widely used in various miniature electronic products. It is generally used as a backup power supply for various electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic hearing aids, and cameras. [0003] When the existing button batteries are applied to electronic products, a plurality of single cells are mostly formed into a battery pack to meet the voltage and current requirements of the electronic products. Due to the unique behavior of the battery pack, it is not a simple addition and subtraction of a single battery to obtain the performance of the battery pack. Ideally, the single cells in th...
