Description

technical field [0001] The invention relates to the technical field of batteries, and in particular to a lithium 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 electrici...
