SYSTEMS AND METHODS FOR CONTINUOUS ALKALINE LEAD ACID BATTERY RECYCLING FOR CONTINUOUS ALKALINE BATTERY RECYCLING

摘要

The lead is recycled from the lead paste of the lead accumulators in a process that utilizes the subsequent alkaline desulfurization followed by formation of the plumbite which is converted to pure lead by electrolysis in the future. Residual insoluble lead dioxide is removed from the lead plumbite solution and reduced to produce lead oxide that can be fed back into the recovery system. Sulfate is recovered as sodium sulfate and the resulting lead oxide can be added as a lead paste for recovery.
