Embodiment Construction

[0008] Place the supercapacitor cell in the aluminum-plastic packaging film of the determined size, and add a getter to the inside of the aluminum-plastic packaging film or coat it on the inner wall of the packaging film to make a square flexible packaging supercapacitor, and the electrolyte is added from the liquid injection port , and then reseal. The composition, dosage and use effect of air getter are as follows:

Abstract

The invention discloses a flexible package super capacitor getter comprising the following components: one or several of a C-C unsaturated bond compound, barium-lithium alloy, a cobalt oxide and a calcium oxide combined in any proportion. A C-C unsaturated bond is an olefin C-C double bond or alkyne C-C triple bond. By adding the getter to the inside of a flexible package super capacitor or coating the getter to the inner wall of a packaging film, gas generated by an electrolyte can be synthesized into a new compound to prevent the risk caused by the reason that the internal gas pressure in the sealed capacitor rises, thereby effectively improving the safety of the flexible package super capacitor and greatly prolonging the cycle life.

Description

technical field [0001] The invention relates to a supercapacitor material, in particular to a getter added to the inside of a soft-packed supercapacitor. Background technique [0002] As we all know, supercapacitors with common structures, including cylindrical and square, button-type supercapacitors, have their own safety valves or explosion-proof valves, which help to discharge the gas formed inside and prevent explosions; while soft-package supercapacitors are Completely sealed structure, no exhaust port and safety valve, the gas generated is confined in the capacitor package, the confined gas will cause the internal pressure of the capacitor to increase, resulting in the softening of the supercapacitor, affecting the performance and life, if If the air pressure reaches a certain level and fails to discharge in time, there will be dangerous phenomena such as liquid leakage, explosion, and fire. This is an urgent problem to be solved for flexible packaging supercapacitors...
