Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] As shown in the figure, the output structure of the low internal resistance organic supercapacitor includes positive electrode 2, negative electrode 4, separator 3, aluminum-plastic film 6 and other parts. The positive and negative electrodes 2 and 4 are made of aluminum foil collectors and coated on the collectors. active substance composition. The positive and negative electrodes of the supercapacitor adopt a planar output structure. The positive output surface 1 and the negative output surface 5 are respectively on the upper and lower sides of the supercapacitor. planes in close contact.

[0017] The active material slurry is evenly coated on the corroded aluminum foil current collector according to the conventional method, and after drying, it is cut into corresponding size pole pieces as the positive electrode 2 and the negative electrode 4...

Abstract

The invention provides an organic super capacitor with low internal resistance, which comprises an electric core and an aluminum-plastic film, and is characterized in that the super capacitor has a double-faced output structure, the front and the back of the super capacitor are provided with an anode output face and a cathode output face respectively, the anode output face contacts with a non-coating face of an anode piece on the outermost side of the electric core, the cathode output face contacts with a non-coating face of a cathode piece on the outermost side of the electric core, and the aluminum-plastic film is provided with windows exposed out of the anode output face and the cathode output face and is in press fit with the periphery of the anode output face and the cathode output face. As compared with an existing organic super capacitor of a terminal output structure and a polar lug structure, the organic super capacitor with the low internal resistance is simple in structure and convenient in manufacture, materials are saved, the internal resistance inside the super capacitor is greatly reduced, and single super capacitors in series connection are convenient in combination and small in connecting resistance, so that heavy current output performance of the single super capacitors and a super capacitor group is remarkably improved.

Description

technical field [0001] The invention relates to a supercapacitor, in particular to a low internal resistance organic supercapacitor with an important improved output structure. Background technique [0002] Supercapacitor, also known as electric double layer capacitor (EDLC), 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 used in a variety of applications. Used as a power balance power supply for lifting devices, it can provide super-large current power; used as a vehicle starting power supply, the starting efficiency and reliability are higher than traditional batteries, and can replace traditional batteries in whole or in part; used as traction energy for vehicles It can produce electric vehicles, replace traditional internal combustion engines, and transform existing trolleybuses; it can be used in the militar...
