Abstract

The invention relates to a total-manganese flow battery. The battery comprises a battery module, an electrolyte storage tank, a circulating pump and a circulation pipeline, wherein the battery module is formed by connecting a single battery or more than two single batteries in series, the single battery comprises a positive electrode and a negative electrode, the positive electrode and the negative electrode are oppositely arranged, a gap is reserved between the positive electrode and the negative electrode, an electrolyte is an acidic aqueous solution containing divalent manganese ions, the positive electrode and the negative electrode share the same electrolyte, and the electrolyte is supplied in a circulation flow way by the circulating pump. In the battery, deposition-dissolution reaction is adopted by the reaction of the positive electrode and the negative electrode, a diaphragm is not needed, only one electrolyte loop is needed, the problem of cross contamination of the traditional flow battery is solved, and the total-manganese flow battery has the characteristics of long cycle lifetime, low cost and simplicity in structure and manufacturing process.

Description

technical field

[0001] The invention relates to an all-manganese liquid flow battery, which can be widely used in the fields of electronics industry, transportation, mining and metallurgy, and the like. Background technique

[0002] Since the industrial revolution, with the continuous growth of the global population and the continuous improvement of living standards, the demand for energy has also risen with the tide. However, the current energy structure dominated by fossil energy is obviously unable to support social development, so developing green and efficient renewable energy and increasing its proportion in the energy supply structure is an inevitable choice to achieve sustainable human development. As the main body of renewable energy: wind energy and solar energy are affected by the natural environment and geographical conditions such as day and night, season change, etc., and the electric energy output has the characteristics of fluctuation and discontinuity, which...
