Embodiment Construction
[0022] Such as figure 1 , figure 2 As shown, the supercapacitor cover plate 1 of the present invention has a pole 11 and a liquid injection hole 12; the pole 11 is formed by extending outward along the end surface of the cover plate 1, and the liquid injection hole 12 is vertically downward along the axial direction of the pole 11 Open to inject electrolyte into the supercapacitor.
[0023] There is one pole 11 located at the center of the cover plate 2 .
[0024] The liquid injection hole 12 may be a threaded hole, and a sealing device 13 for sealing the liquid injection hole 12 is arranged in the liquid injection hole 12 . Such as image 3 As shown, the sealing device 13 includes a screw 131 matched with the liquid injection hole 12 and a sealing ring 132 sleeved on the screw 131. The screw 131 is screwed into the liquid injection hole 12 and under the cooperation of the sealing ring 132, the Injection hole 12.
[0025] In order to improve the sealing performance of th...

The invention relates to a cover plate for an electric double-layer capacitor and an electric double-layer capacitor. The cover plate is provided with a terminal and a liquid injection hole, wherein the liquid injection hole is positioned on the terminal and is vertically formed downwards along the axial direction of the terminal. The electric double-layer capacitor is provided with the cover plate, wherein the liquid injection hole of the cover plate is vertically formed downwards along the axial direction of the terminal. The cover plate for the electric double-layer capacitor is not required to be thickened for strength improvement, and has explosion protection and pressure relief functions; and since a cover plate structure is adopted by the electric double-layer capacitor, the internal effective volume is expanded, the capacity of the entire electric double-layer capacitor is increased, phenomena such as shell bulging, valve explosion and the like of the electric double-layer capacitor are avoided, and the service life is prolonged.
Description
technical field [0001] The invention belongs to the field of energy storage components, and relates to a supercapacitor cover plate and a supercapacitor with the cover plate. Background technique [0002] Supercapacitor (Electric double-layer capacitor) is a special energy storage element developed in recent years between traditional electrostatic capacitors and electrochemical power sources; due to its advantages of high power density, long cycle life and fast charging speed , has broad application prospects in various fields such as mobile communications, solar and wind power generation, information technology, and electric vehicles. [0003] Commonly used supercapacitors include a metal case with an open end, a core installed in the metal case, and a cover plate for sealing the open end of the metal case. In order to inject electrolyte into the metal case, usually on the surface of the cover plate There is a liquid injection hole on the top, through which the electrolyte...
