An installation for producing batteries is disclosed, having a lead bath station with two heatable and mobile lead bath carriages arranged in an assignable manner at the stationary lead melting pot. Both carriages having a pumping-sucking device that serves for the changing of the lead bath. Molten lead is pumped out of the lead pot into an empty carriage. Both the pumping-sucking devices are arranged pivotably about the axis of rotation (B) and the pivot pin that is fixedly arranged on the carriage is arranged such that it can be separately pivoted about the axis of rotation (A), thus, making it possible for the suction tube and a discharge tube to be moved between the carriage and the led pot.

Methods for making lead-carbon coupling, lead-carbon electrode sheets, and a lead-carbon battery are revealed. The coupling methods consist of steps of assembling the carbon material that contains oxygen functional groups or metal precursors and lead material in contact with each other and then heating the assembled lead-carbon pair to form lead oxides or metal carbides as a bridge to form coupled lead-carbon interface with high electrochemical and mechanical stability. This coupled lead-carbon structure is applied to form lead-carbon electrode sheets and is further used as electrode sheets of lead-carbon batteries by lead welding.
