Abstract

The invention discloses a high-power-density super-capacitor slurry preparation method. High-power-density super-capacitor slurry comprises active substances AC, binding agents LA132, conductive agents SP and butadiene styrene rubber SBR, the weight ratio of the active substances AC, the binding agents LA132, the conductive agents SP to the butadiene styrene rubber SBR is 90:5:3:2, active substances are increased by 4% as compared with the previous content in a product, the capacity of a product is increased by 4.5% or more, the energy density of the product is improved, the adhesive force ofan aluminum foil can be increased by the aid of two binding agents, the internal resistance of the product is reduced, the power density of the product is improved, mixing time can be effectively shortened by 2 hours, production efficiency is improved by 20%, flexibility of pole pieces is improved, powder falling in rolling and cutting processes is avoided, and scrap caused by short circuit in rolling-in, flattening and shell entering processes is decreased.

Description

technical field [0001] The invention relates to a preparation method for proportioning, in particular to a preparation method for high power density supercapacitor slurry. Background technique [0002] Energy crisis and environmental protection have become the strategic core of sustainable development of human beings. They are the key factors affecting energy decision-making and scientific and technological guidance of all countries in the world today. At the same time, they are also a huge driving force to promote the development of energy science and technology. The development of new energy is a major issue that must be solved in the 21st century. With the development of science and technology and the advent of the information age, various electronic equipment, new energy vehicles, military industry, national grid and various computers have more and more demands for high-performance storage backup power. The requirements are getting higher and higher, and there is also a...
