Abstract

The invention relates to a zinc-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, and an electrolyte is an acidic aqueous solution containing divalent zinc ions and divalent manganese ions. In the battery, solid-liquid phase conversion is adopted during 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 zinc-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 a zinc-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] With the continuous increase of population and the improvement of living standards, people's demand for energy is soaring. Traditional fossil energy will not be able to meet people's needs in the near future. Therefore, the development and utilization of renewable energy such as wind energy and solar energy are subject to extensive attention. However, these renewable energy sources are discontinuous, unstable, restricted by regional environment, and difficult to connect to the grid, resulting in low utilization rate, high wind and light abandonment rate, and waste of resources. Energy storage technology can improve the utilization rate and stability of renewable energy through the storage and release of capacity, and is a key technology for the ...
