Wirelessly-charged hearing aid battery

Abstract

The invention relates to a battery, particularly a wirelessly-charged hearing aid battery, and belongs to the technical field of the hearing aid battery. According to the technical scheme provided by the invention, the wirelessly-charged hearing aid battery comprises a battery shell, a coiled core positioned in the battery shell, and a positive tab and a negative tab which are electrically connected with the coiled core; the battery shell is made from an aluminum plastic film; and the positive tab and the negative tab are insulated and isolated from the battery shell through an insulating layer. According to the wirelessly-charged hearing aid battery, the shell main body and the shell cover are matched and sealed to form the battery shell; the shell main body and the shell cover are both made from the aluminum plastic film, so that the flexibly-packaged hearing aid battery is obtained; the positive tab and the negative tab are insulated and isolated from the battery shell through the insulating layer, so that an inductive effect between the tabs and the battery shell is prevented in the wireless charging process; and therefore, the wireless charging requirement of the hearing aid battery is satisfied, the service life of the battery is prolonged, and the battery is safe and reliable.

Description

technical field [0001] The invention relates to a battery, in particular to a wirelessly chargeable hearing aid battery, belonging to the technical field of hearing aid batteries. Background technique [0002] Conventional hearing aid batteries use steel-shell button-type lithium-ion batteries, and the tabs of the internal cells are in direct contact with the metal shell. Because of the inductive effect in the wireless charging process, the internal structure of the battery will be destroyed, resulting in a rapid decline in battery performance and long cycle life. plummeted. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a wirelessly chargeable hearing aid battery, which has a compact structure, meets the wireless charging requirements of the hearing aid battery, prolongs the service life of the battery, and is safe and reliable. [0004] According to the technical solution provided by ...
