Abstract

The invention relates to a super-capacitor based on activated carbon / sodium copper chlorophyllin composite electrodes. The super-capacitor comprises an electrolyte, the upper side of the electrode isprovided with a current collector and an electrode from top to bottom, the lower side of the electrode is provided with an electrode and a current collector from top to bottom, and the electrodes arethe activated carbon / sodium copper chlorophyllin composite electrode. According to the super-capacitor, activated carbon is a frequently-used super-capacitor electrode material, the activated carbon and sodium copper chlorophyllin are rich in source, low in cost, green and environmentally friendly, the sodium copper chlorophyllin can serve as an electrode material of super-capacitor to be used andserves as conductive agents in the composite electrodes, and the sodium copper chlorophyllin can replace relatively high-cost conductive agents for other activated carbon electrodes when the performances of the super-capacitor are kept, so that the manufacturing cost of the super-capacitor based on activated carbon is reduced.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to a supercapacitor based on an activated carbon / sodium copper chlorophyllin composite electrode and a preparation method thereof. Background technique [0002] Among the factors affecting the performance of supercapacitors, the electrode material is the most critical factor. The materials currently used for supercapacitor electrodes are mainly divided into three categories, including: carbon electrode materials, metal oxide materials, and conductive polymer materials. Among them, carbon electrodes made of carbon materials are the most common. Carbon materials are the main branch of the earliest research, the most widely used, and the most commercially mature electrode materials. Carbon materials used in supercapacitor electrodes include activated carbon, carbon aerogels, carbon nanotubes, and graphene. The main advantages of carbon materials include large spec...
