Capacitance-adjustable double-electric-layer capacitor and packaging method thereof

Abstract

The invention discloses a capacity-adjustable double-electric-layer capacitor, which comprises a packaging shell, a sealing cover, an electrode group, an air bag group, a pump body, a plunger and an adjusting screw rod, the sealing cover and the packaging shell form a closed electrolyte cavity, and the electrolyte cavity is filled with electrolyte; the two electrode groups are arranged in the electrolyte cavity side by side at intervals, each electrode group comprises an electrode body, each electrode body is provided with a lead, each electrode body is provided with a collector plate, the lead penetrates through the sealing cover and then extends out, and the surface of each collector plate is coated with a carbon electrode coating; the air bag group is arranged at the inner bottom of the packaging shell and is provided with an air inlet hole; the pump body is fixed to the bottom face of the sealing cover, and an exhaust hole is formed in the bottom of the pump body and communicated with the air inlet through a connecting pipe. The plunger is arranged in the pump body; the adjusting screw rod is rotationally connected to the sealing cover, and the lower end of the adjusting screw rod extends into the pump body and then is in threaded sleeve connection with the plunger; according to the invention, the capacitance can be adjusted, the charging time can be reduced, and the diversified requirements on the capacitance are met.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to an electric double layer capacitor with adjustable capacity. Background technique [0002] The capacitance of the current electric double-layer capacitor is a fixed value, and the capacitance of the electric double-layer capacitor cannot be adjusted according to the actual use requirements; however, in practical applications, the capacitance requirements of the electric double-layer capacitor are often diversified. If the electric capacity is too small, it cannot provide stable power output, and if the electric capacity is too large, the charging process takes a long time and cannot meet the work needs. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above shortcomings and provide an electric double layer capacitor with adjustable capacity. [0004] For achieving the above object, the concrete scheme of the present invention is as f...
