Abstract

The invention relates to a capacitor, more particularly a super capacitor having high capacity and serving as a main traction-type energy storage device, belonging to a novel electrochemical energy-storage environment-protection device. The traction-type energy storage device comprises a capacitor core consisting of a positive electrode plate (1), a negative electrode plate (2), an insulation membrane (3) and electrolyte solution, and is characterized in that a negative active material is formed by mixing active carbon with high specific surface area, hydrogen storage alloy, carbon nanotube, and binder. The inventive super capacitor has the advantages of large power density, high charge-discharge speed, long service life, wide working temperature range, free of maintenance and pollution, and high battery storage capacity. The storage energy of the super capacitor can be improved by multiples and more approaches to a battery, and simultaneously the available voltage use range of the capacitor is widened. The invention has wide application in traffic, electric power, military, power supply and communication fields.

Description

1. Technical field [0001] The invention relates to a capacitor, in particular to a supercapacitor with high energy storage and used as a main traction energy storage device, which belongs to a novel electrochemical energy storage environmental protection device. 2. Background technology [0002] Supercapacitors, also known as electric double layer capacitors and electrochemical capacitors, were gradually developed on the basis of the principle of an electrochemical interface electric double layer obtained by German physicist Helmholtz in the 19th century. A supercapacitor is a new type of energy storage device between rechargeable batteries and traditional capacitors. It has high power density, high storage density, fast charging and discharging, long service life, wide working temperature limit, maintenance-free, and pollution-free. It is a new, efficient and practical energy storage device. [0003] Since the 1990s, the progress of industry has brought unprecedented civil...
