Embodiment Construction

[0013] The present invention will be further described below in conjunction with drawings and embodiments.

[0014] First, the supercapacitor positive pole piece 3 and the negative pole piece 4 are produced in a conventional manner, and the positive pole tab 1 and the negative pole tab 2 of the nickel-plated steel strip material are respectively welded on the pole pieces, and the positive pole piece 3 and the negative pole tab 2 of the welding tab are welded respectively. The negative pole pieces 4 are stacked sequentially, and are separated by a diaphragm 8 between the positive and negative poles. Then wrap the electrode with a flexible packaging film 5 made of polyethylene film, polypropylene film or aluminum-plastic film, put the exhaust pipe 7 made of polyethylene or polypropylene, and seal the surroundings of the flexible packaging film 5 with a heat sealer.

[0015] Inject 6mol / L potassium hydroxide electrolyte into the supercapacitor through the exhaust pipe 7, then put...

Abstract

The invention provides a super capacitor of a flexible package water system. The super capacitor is characterized in that a polyethylene film, a polypropylene film, an aluminum-plastic film and other packaging films are taken as shells; the packaging films can be cut into any shaped packaging films as needed; the any shaped package films are subjected to heat seal to obtain good sealing effect. The upper part of the super capacitor is provided with an exhaust pipe which is used for discharging gas generated by using the super capacitor for a long time; meanwhile, the upper part of the exhaust pipe is filled with polytetrafluoroethylene filtrate sheets, so that leakage can be effectively prevented. Due to adoption of the flexible package, the super capacitor is low in cost, is not restricted by common shell sizes, is simple in production process, light in product quality and small in volume, and is convenient to freely assemble; and in addition, the power-to-weight ratio of the super capacitor is large. The novel flexible package and an exhaust pipe structure are adopted for the super capacitor, thus effectively solving the problem of shell package for super capacitors of existing water systems.

Description

technical field [0001] The invention relates to a soft-package water-based supercapacitor, which belongs to the technical field of supercapacitors. Background technique [0002] Supercapacitor is a new type of energy storage product developed in recent years between physical capacitors and chemical power sources. Its storage capacity is several orders of magnitude larger than that of ordinary capacitors, and its cycle life is tens to hundreds of times that of ordinary chemical power sources. Supercapacitors increase the energy storage capacity by using porous activated carbon materials to increase the area of ​​the bipolar plates. Supercapacitors have the advantages of high power density of conventional capacitors, and can be charged and discharged quickly and efficiently. Its charges are stored on the surface of activated carbon with high specific surface area, no chemical reaction occurs, and it has the outstanding advantages of long life, high power, maintenance-free, gr...
