摘要： The present disclosure relates generally to systems and methods for recycling lead-acid batteries, and more specifically, relates to purifying and recycling the lead content from lead-acid batteries. A system includes a reactor that receives and mixes a lead-bearing material waste, a carboxylate source, and a recycled liquid component to form a leaching mixture yielding a lead carboxylate precipitate. The system also includes a phase separation device coupled to the reactor, wherein the phase separation device isolates the lead carboxylate precipitate from a liquid component of the leaching mixture. The system further includes a closed-loop liquid recycling system coupled to the phase separation device and to the reactor, wherein the closed-loop liquid recycling system receives the liquid component isolated by the phase separation device and recycles a substantial portion of the received liquid component back to the reactor as the recycled liquid component.

摘要： A lead-acid battery is disclosed. The lead-acid storage battery has a container with a cover, the container including one or more compartments. One or more cell elements are provided in the one or more compartments. The one or more cell elements include a positive plate, the positive plate having a positive grid and a positive electrochemically active material on the positive grid; a negative plate, the negative plate having a negative grid and a negative electrochemically active material on the negative grid, wherein the negative electrochemically active material comprises barium sulfate and an organic expander; and a separator between the positive plate and the negative plate. Electrolyte is provided within the container. One or more terminal posts extend from the cover and are electrically coupled to the one or more cell elements.

摘要： The present disclosure relates generally to systems and methods for recycling lead-acid batteries, and more specifically, relates to purifying and recycling the lead content from lead-acid batteries. A system includes a reactor that receives and mixes a lead-beating material waste, a carboxylate source, and a recycled liquid component to form a leaching mixture yielding a lead carboxylate precipitate. The system also includes a phase separation device coupled to the reactor, wherein the phase separation device isolates the lead carboxylate precipitate from a liquid component of the leaching mixture. The system further includes a closed-loop liquid recycling system coupled to the phase separation device and to the reactor, wherein the closed-loop liquid recycling, system receives the liquid component isolated by the phase separation device and recycles a substantial portion of the received liquid component back to the reactor as the recycled liquid component.
