Problems solved by technology

In the shell structure of supercapacitors, it is generally stretched and formed with pure aluminum. The inner wall of the shell is a planar structure, which fits closely with the internal cells, which is not conducive to the penetration of the electrolyte, and the product capacity is low at one pass. The strength of the aluminum material is relatively low, and there is a problem of shell deformation and swelling, which affects the assembly and application of the module system

Abstract

The invention discloses a super capacitor casing. The super capacitor casing comprises a casing formed by walls, wherein the casing is provided with an accommodation space used for accommodating electrolyte and solid liquid phase substances including other structures and further comprises reinforcement ribs, the reinforcement ribs are formed on the walls and project towards an internal space, connection portions of the walls and the reinforcement ribs and / or the reinforcement ribs and / or the walls are provided with diversion structures at one side of the accommodation space, and the diversion structures are used for facilitating electrolyte flowing. The super capacitor casing has advantages of simple structure, high electrolyte conveying efficiency, high casing strength, good environment survivability and long service life.

Description

technical field [0001] The invention relates to spare parts of a supercapacitor, in particular to a casing of a supercapacitor. Background technique [0002] Supercapacitor is a new type of supercapacitor for energy storage. Compared with batteries and traditional capacitors, it has the advantages of high power density, short charge and discharge time, long cycle life, and wide operating temperature range. It can meet the requirements of different application fields. . In the shell structure of supercapacitors, it is generally stretched and formed with pure aluminum. The inner wall of the shell is a planar structure, which fits closely with the internal cells, which is not conducive to the penetration of the electrolyte, and the product capacity is low at one pass. The strength of the aluminum material is relatively low, and there is a problem of shell deformation and swelling, which affects the assembly and application of the module system.
