Abstract

The invention relates to an acid single flow cell which can be applied to large-scaled energy storage and power generation. The cell comprises an electrolyte storage tank, a cadmium or indium deposited cathode current collector and a lead dioxide anode; an acid solution of soluble cadmium salt or indium salt is used as an electrolyte; and when the cell is charged, the cadmium or indium ions are deposited on the cathode current collector from the electrolyte, and when the cell is discharged, the metal cadmium or indium is dissolved in the electrolyte from the cathode current collector. The current cell has the advantages of simple structure, convenient preparation, high electric energy conversion efficiency, long cycle life, environmental protection, safe use, and the like.

Description

Technical field:

[0001] The invention relates to an acidic single flow battery which can be used for large-scale energy storage and power generation. Background technique:

[0002] Electric energy is an important guarantee for the development of the national economy and an important foundation for the modern defense industry. The sufficient supply and efficient utilization of electric energy are of great practical significance. In order to achieve stable power supply, it is of great significance to develop efficient large-scale energy storage technology. In order to solve and improve the power supply problems in remote areas of our country, it is necessary to establish a distributed power supply system. The large-scale energy storage unit is the "power bank" of the distributed power supply system, which plays an extremely important role and is also one of the key technologies that must be effectively solved.

[0003] The flow battery in the chemical storage battery, or flow...
