Problems solved by technology

However, due to changes in ambient temperature, especially in summer and winter, the temperature in summer is high, and the electrolytic cell is prone to hot cells, and the current efficiency of electrolysis is significantly reduced. In winter, the temperature is low, and the electrolytic cell is prone to cold cells, which also affects the current efficiency

Abstract

The invention discloses a temperature adjustable lithium metal electrolytic bath. The temperature adjustable lithium metal electrolytic bath comprises an outer bath body, a lining body, cathodes, anodes and a bath cover covering the upper parts of the outer bath body and the lining body; a chlorine gas exhausting hole and a lithium metal discharging hole are formed in the bath cover, the cathodes are arranged around the anodes, the anodes are uniformly distributed in the lining body, the cathode is connected with a cathode busbar, the anode is connected with an anode busbar, the cathode is fixed inside the lining body, a sealing interlayer is formed between the outer bath body and the lining body, a heat preservation layer is arranged at the upper part of the inside of the sealing interlayer, a ventilation cavity is formed at the lower part of the sealing interlayer, an air inlet is formed on the side surface of the outer bath body, an air outlet is formed on the other side surface of the outer bath body, an air supplying device is connected outside the air inlet in a sealing manner, and an exhausting device is connected outside the air outlet in a sealing manner. The temperature adjustable lithium metal electrolytic bath has simple structure, the temperature of the electrolytic bath can be adjusted according to the environment temperature, the current efficiency of the electrolytic bath is improved and the lithium metal production cost is reduced.

Description

technical field [0001] The invention relates to an electrolytic cell, in particular to a temperature-adjustable metal lithium electrolytic cell. Background technique [0002] Molten salt electrolysis of a mixture of molten lithium chloride and potassium chloride is currently the only method for the industrial production of lithium metal. The electrolytic cell is the key equipment of electrolysis, and the structure and process parameters of the electrolytic cell determine the economic and technical indicators of electrolysis. The electrolytic cell is generally composed of a cell body, a cell lining, a cell cover, an anode and a cathode. According to the number of anodes, it can be divided into a single anode electrolytic cell and a multi-anode electrolytic cell. Plug-in electrolyzer, bottom plug-in electrolyzer and side plug-in electrolyzer, all kinds of electrolyzers are sandwiched between the tank body and the inner lining, and the insulation material is fixedly filled in ...
