Abstract

The invention discloses a super capacitor, which comprises a casing, a core body and an end cover, wherein the two ends of the casing are respectively provided with a water inlet and a water outlet communicated with an inner cavity of the casing, electrolyte is contained in the inner cavity of the casing, the core body is arranged in the electrolyte, the core body comprises electrode groups, an electrode post and a baffle plate, the electrode groups are penetrated and arranged on the electrode post in a staggered way, one end of the electrode post is screwed on the end cover, the other end of the electrode post is screwed on the baffle plate, the end cover is screwed on a flange arranged at the opening end of the casing, and a flow guide hole communicated with the inner cavity of the casing is arranged on the end cover. The core body of the super capacitor is completely independent from the casing and can be singly manufactured, the length of the core body can be freely set, and then, the casing with the matched length is adopted. The core body can singly adopt the ultra-high laminating pressure, so the contact of each layer of electrode array is tighter, the internal resistance is lower, the external deformation and the sealing do not need to be considered, the casing only bears the flowing pressure of the electrolyte, the deformation and the leakage are avoided, and the service life is greatly prolonged.

Description

technical field

[0001] The invention relates to a capacitor, in particular to a super capacitor. Background technique

[0002] Supercapacitor is a new type of energy storage device, which has the characteristics of short charging time, long service life, good temperature characteristics, energy saving and environmental protection. Supercapacitors are versatile: they can be used for energy storage, and they can also be applied to the adsorption and desorption of ions. Supercapacitors currently used for ion adsorption and desorption generally adopt the overall manufacturing and packaging method: the bottom of the supercapacitor shell is screwed with an electrode column, and several electrode groups are worn on the electrode column, and then the upper end cap is pressed on the electrode group. On the top, the end cover and the shell are screwed together to form an integrated structure. When the electrode group of this integrated supercapacitor is adsorbed and desorbed, due to...
