Problems solved by technology
[0009] Existing liquid metal batteries have a high working temperature, and all use vertical electrodes directly inserted into the liquid metal, and are sealed by sealing rings. Therefore, the electrodes are severely corroded, and the sealing rings are not resistant to high temperature corrosion, and open circles often occur, which shortens the life of the electrodes. Short, which seriously affects the normal operation of the battery. Due to poor heat preservation, the battery pack must be sealed in an incubator and heated externally, which affects the industrial promotion and application of liquid metal batteries.

Description
technical field [0001] The invention relates to the technical field of liquid metal batteries, in particular to an industrially applied liquid metal battery and an application method thereof. Background technique [0002] Liquid metal batteries are a new type of electrochemical energy storage technology emerging in recent years, and have broad application prospects in the field of large-scale energy storage. The concept model of the liquid metal battery can be traced back to the three-layer liquid Hoopes aluminum electrolytic cell proposed by Alcoa in the early 20th century. The liquid state of the layers is that the upper layer is a low-density high-purity liquid aluminum cathode obtained by refining, the lower layer is a high-density copper-aluminum alloy positive electrode, and the middle layer is a molten salt electrolyte. In the 1960s and 1970s, research topics in similar directions such as "thermally regenerative bimetallic batteries" were repeatedly discussed and stu...
