Abstract

A carbon electrode for electric double layer capacitor, which comprises a metal base foil, the first carbon electrode layer and the second electrode layer. The metal base foil has a first surface and a second surface opposite to each other and a plurality of holes are distributed on the both surfaces. The first electrode layer and the second electrode layer are arranged on the first surface and the second surface respectively. The first carbon electrode layer and the second carbon electrode layer are single-layer structure. The carbon electrode layer and the second carbon electrode layer are embedded into the hole, so that a plurality of conductive interfaces are provided between the first electrode layer and the metal base foil and between the second electrode layer and the metal base foil.

Description

technical field [0001] The invention relates to an electric double-layer capacitor, in particular to a carbon electrode of an electric double-layer capacitor, a manufacturing method thereof, and an electric double-layer capacitor having the carbon electrode of the electric double-layer capacitor. Background technique [0002] Electric double-layer capacitors, also known as supercapacitors, are 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. Electric double-layer capacitors are widely used. For example, they can be used as a power balance power supply for lifting devices, which can provide super-high current power; 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, can produce ele...
