Patent number: 11005129Abstract: 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.Type: GrantFiled: August 30, 2019Date of Patent: May 11, 2021Assignees: Clarios Germany GmbH & Co. KGAA, CPS Technology Holdings LLCInventors: Eberhard Meissner, Jr., Jurgen Bauer, Matthew A. Spence

Patent number: 10978685Abstract: A sealing plug arrangement for sealing a combined filling and degassing opening of an accumulator. The sealing plug arrangement includes at least one valve part, one valve holder, and one sealing plug. The valve part is arranged on the valve holder and forms an openable valve mechanism with the valve holder for sealing at least one interior space of the accumulator from the surrounding area upon pressurization. The sealing plug includes at least one fastening means for fixing to the filling and degassing opening and at the same time subjecting the valve part to a pretensioning force toward the valve holder. The valve holder includes at least one extension axially projecting toward the valve part which is formed as a circumferential sealing edge on a surface facing the valve part on which the valve part rests.Type: GrantFiled: May 28, 2014Date of Patent: April 13, 2021Assignee: Clarios Germany GmbH & Co.
