Methods of performing electrolytic reactions in scaled electrolytic cells, methods of passivating electrolytic cell components, and associated systems and electrolytic cells are generally described. Some methods comprise performing electrolytic reactions in sealed electrolytic cells in a manner that results in the passivation of one or more electrolytic cell components.

Disclosed is a method for leaching lithium via an electrochemical apparatus including a multi-functional current collector, an electrode, an electrolyte, and a lithium-bearing material, wherein the lithium-bearing material is dispersed or suspended in the electrolyte or the lithium-bearing material is coated onto the current collector. The method involves applying voltage to the current collector to leach lithium from the lithium-bearing material. The method can involve adding promoter additive into the electrolyte to boost lithium extraction within the electrochemical apparatus.

A multi-anode electrolytic cell relating to molten salt lithium electrolysis. The cell includes a sealed container with at least two electrode groups uniformly arranged inside. Each group has an anode and a cathode, and the top end of the anode penetrates the top end of the sealed container to protrude out of the sealed container. A separation mesh is arranged on the outer side of the anode. The cathode is arranged on the outer side of the separation mesh and connected with a conducting plate. The top end of the conducting plate protrudes out of the top end of the sealed container. A bottom-removed collecting hood is arranged above the cathode such that it surrounds the outer side of the anode. The physical fields in the sealed container are uniformly distributed by uniformly arranging the electrode groups, thereby ensuring a continuous and stable electrolysis process.
