According to the different electrolytes, they are divided into three categories: aqueous solution electrolytic cell, molten salt electrolytic cell and non-aqueous solution electrolytic cell. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce the desired product.
