Example Embodiment

[0011] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0012] by Figure 1 to Figure 4 Given that the present invention includes a shell 1 filled with electrolyte solution, a core 2 placed inside the shell 1, and an end cover 3. The end cover 3 is screwed on the first flange 4 at the open end of the shell 1. Its characteristics are It also includes a housing 5 containing the housing 1, the core 2 and the end cover 3. The housing 1 and the housing 5 are arranged coaxially with their open ends in the same direction. The second flange 6 at the open end of the housing 5 is screwed Equipped with an outer cover 7, the end cover 3 and the outer cover 7 form a sealed isolation cavity between the shell 1 and the shell 5. The isolation cavity is filled with electrolyte solution; the end cover 3 has an upper part of the end cover 3 A vertical extension tube 8 is provided, and the upper end of the ext...

Abstract

The invention relates to a super capacitor. The technical scheme of the super capacitor is characterized in that the super capacitor comprises a housing, a core body at the inner side of the housing and an end cover; the end cover is screwed with a first flange at the opening end of the housing; the super capacitor also includes a shell accommodating the housing, the core body and the end cover; the housing and the shell are arranged coaxially; an outer cover is screwed with a second flange of the opening end of the housing; the end cover is provided with a protruding tube which is arranged above the end cover; the upper end of the protruding tube penetrates the outer cover; the end cover is provided with a floater composed of a floating ball and a vertically arranged slide rod; the floating ball is arranged at the inner side of the housing; the slide rod is vertically slidably connected to the end cover and is arranged coaxially with the protruding tube; vertical through holes communicated with inner holes of the protruding tube are formed in the end cover; air inlet holes vertically penetrating the outer cover are formed in the outer cover; and a first one-way valve is arranged at the lower portion of the housing.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a super capacitor. Background technique [0002] Supercapacitor is a new type of energy storage device, which has the advantages of high power density, short charge and discharge time, long cycle life, and wide operating temperature range. However, due to its own structural limitations, its internal At the same time, due to the large number of electrode groups of supercapacitors, the expansion and contraction caused by the adsorption and desorption of ions during operation will accumulate and superimpose on each layer of electrode groups, which will easily cause damage to the seal. The damage of the electrolytic solution will cause the leakage of the electrolyte solution; and in the process of use, once the electrolyte solution is used improperly, the leakage of the electrolyte solution will also occur. [0003] When the electrolyte solution leaks, on the one hand, the reduct...
