Abstract

The invention provides a chlorine-magnesium battery and an energy storage method thereof, and relates to the technical field of batteries. The chlorine-magnesium battery comprises a battery body, a chlorine gas circulation device and an electrolyte circulation device, wherein the battery body comprises a shell and a membrane assembly; the membrane assembly is arranged in the shell and partitions the shell into an anode area and a cathode area; a magnesium salt non-aqueous electrolyte is arranged in the shell; an anode plate for chlorine gas reaction is arranged in the anode area; a cathode plate is arranged in the cathode area; the anode area communicates with the chlorine gas circulation device; and the cathode area communicates with the electrolyte circulation device. The energy storage method of the chlorine-magnesium battery comprises the steps of electrically connecting a power generation device and the chlorine-magnesium battery and inputting an electrolyte into the chlorine-magnesium battery; and collecting a generated chlorine gas for cyclic utilization. The chlorine-magnesium battery belongs to a large power storage device and is mainly used for power storage equipment or a power station of an intermittent power generation device. The chlorine gas generated by the chlorine-magnesium battery in the working process and the electrolyte can be collected for cyclic utilization through the chlorine gas circulation device and the electrolyte circulation device.

Description

technical field [0001] The invention relates to the technical field of batteries, and in particular to a magnesium chloride battery and an energy storage method thereof. Background technique [0002] As the most important secondary energy source, electric energy has made important contributions to the development and progress of human society. Electric energy is mainly obtained through conversion of other primary energy sources, so an energy crisis directly affects the stable supply of electric energy. In my country, the economic losses caused by power cuts during the peak load period of electricity consumption are incalculable, and the environmental pollution caused by traditional thermal power generation cannot be ignored. [0003] Currently, electricity production and consumption occur almost simultaneously. Power shortage and environmental deterioration have become two major problems restricting the sustainable development of our national economy. How to store electri...
