Technical Field

Background
The lithium electrolysis process relies on the heat generated by the passage of current through the anode, electrolyte and cathode to maintain thermal equilibrium and maintain the temperature and superheat of the electrolyte at suitable levels. The electrolyte can only become liquid if its temperature exceeds its primary crystallization temperature, and a solid electrolyte is needed as a ledge near the cell shell to protect the cell shell from the electrolyte. The difference between the electrolyte temperature and the primary crystal temperature is the degree of superheat. The continuous lithium electrolysis process requires maintaining the superheat at about 20 ℃ and a ledge thickness.
Whether the input energy is matched with the heat preservation or heat dissipation degree of the cell is the key for maintaining proper superheat degree and ledge of the lithium electrolytic cell. After the heat balance is achieved, once the input energy is greatly increased, the heat preservation degree of the electrolytic cell needs to be reduced, otherwise, the electrolytic cell is overheated, and the situations that the superheat degree is too high, the ledge is too thin or even no ledge exists occur.

In general, the amount of input energy needs to be matched to the degree of thermal insulation of the tank.
