The production of electrolytic manganese sheet is in the form of tenon and mortise for the touch of aluminum strip and copper strip, the touch end of aluminum strip is tenon, and the corresponding receiving end of copper strip is mortise; It is also possible that the touch end of the copper head is a tenon, and the corresponding receiving end of the aluminum strip is a mortise; In this way, the touch surface of the two can be greatly increased and the aluminum strip and copper strip can be reduced. Due to the different conductivity, the current is lost when touching. Together, this connection can closely connect the aluminum strip and copper strip, and it is not easy to fall. The touch surface of aluminum strip and copper strip is an inclined plane, and the shape of the inclined plane at the touch point corresponds to each other. Setting the touch surface as an inclined plane can greatly the area touched by copper and aluminum bars, greatly increase the stability of connection and ensure the connection of conductive area together.

　　The exposed parts are all set as copper bars. Due to the corrosion resistance of copper bars, the cathode can be more practical. All the touch parts of aluminum bars and copper bars are sealed in the stainless steel shell, and all the aluminum bars are wrapped in the stainless steel shell, so as to avoid the corrosion of the touch parts and the corrosion of aluminum bars, and improve the service life of cathode. Aluminum bar and copper bar are connected by welding. The aluminum strip and copper strip are connected by welding, which is convenient and stable. As an alternative, the aluminum strip and copper strip can also be closely connected by stamping. The conductive material in the cathode bar for electrolytic manganese sheet is single, and the pure copper with equal cross section is changed into pure copper and pure aluminum with different conductivity according to the actual needs of conductivity. Without changing the conductivity requirements required for the production of electrolytic manganese sheet and increasing the electrolytic power consumption, that is, on the premise that the cathode conductivity of electrolytic manganese sheet remains unchanged, the production cost of electrolytic manganese cathode is reduced by 10-12%, the weight is reduced by 8-9%, and the labor intensity of workers is greatly reduced.
