Copper energy storage battery and production process thereof

Abstract

The invention discloses a copper energy storage battery and a production process thereof. The copper energy storage battery comprises a box body, wherein the surface of the box body is provided with a positive terminal and a negative terminal, the box body is filled with electrolyte, copper negative plates and copper hexacyanoferrate positive plates are arranged in the box body in a staggered manner, the number of the copper negative plates is one more than that of the copper hexacyanoferrate positive plates, the adjacent copper negative plates are connected with each other and are connected with the negative binding post; and the current collecting grids in the adjacent copper hexacyanoferrate positive plates are connected with each other and are connected with the positive binding post. The copper energy storage battery has the advantages of low manufacturing cost, no pollution, high charging and discharging speed, better comprehensive performance than the existing energy storage battery, and low investment and operation cost; copper ferricyanide is adopted as the positive electrode material of the copper energy storage battery, synthesis is simple, and raw materials are easy to obtain; and in order to give full play to the advantage of super-long stability of a copper ferricyanide positive electrode material in strong acid and the properties of rapid intercalation and de-intercalation of copper ions, functionalized porous carbon is adopted as an activating agent of copper ferricyanide, so that a copper ion transmission channel is optimized and adjusted, the oxidation corrosion resistance of a carbon material is enhanced, and the service life of a battery is prolonged. The production process has the technical effect that the copper energy storage battery with high stability, long cycle life, high discharge rate and low price is obtained.

Description

technical field [0001] The invention relates to the technical field of energy storage batteries, in particular to a copper energy storage battery and a production process thereof. Background technique [0002] my country puts scientific and technological innovation at the core of economic development. Scientific and technological innovation will be a basic national policy in the future and a new engine for economic development. The development of clean energy is the guarantee for the smooth implementation of carbon neutrality. In order to develop clean energy and eliminate 70% of the current thermal power generation, energy storage must be installed. Energy storage is an independent industrial system, and there is no solution for energy storage in the future There will be no solution, and the demand for energy storage is expected to explode after 2021. At present, a large amount of wind energy and solar energy cannot be connected to the grid, mainly because 1. The lack of e...
