Abstract

The invention relates to a button lithium battery pre-discharge fixture. The fixture includes a rack, an air cylinder is arranged at the upper end of the rack, an upper fixture body is arranged at thelower end of a piston push rod of the air cylinder, a lower fixture body is arranged below the upper fixture body, and conductive connectors are arranged on the lower end face of the upper fixture body and the upper end face of the lower fixture body; a resistor is arranged at the rear end of the rack, and wires are arranged between the resistor and the conductive connectors. The invention also relates to a work method of the button lithium battery pre-discharge fixture. The fixture is simple in structure and easy to operate, pre-discharging of a button lithium battery can be achieved, the button lithium battery is prevented from generating an oxidized film, and the storage time and service life of the battery are prolonged.

Description

technical field [0001] The invention relates to a button lithium battery pre-discharging fixture and a working method thereof. Background technique [0002] Button batteries are widely used in various miniature electronic products because of their small size. They are generally used as backup power for various electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controls, electric toys, pacemaker etc. [0003] Because the nominal voltage of the existing button lithium battery is higher than that of other button batteries, an oxide film is easily formed on the surface of the button lithium battery, which affects the storage time and service life of the button lithium battery. Contents of the invention [0004] In view of this, the object of the present invention is to provide a button lithium battery pre-discharge fixture and its working method, which can realize the pre-discharge action on the button li...
