Highly porous leady oxides for next-generation lead‒acid batteries — scalable, sustainable, and advanced materials for future batteries

Ever Resource has scaled up a hydrometallurgical process for the recycling of lead‒acid battery paste.  The process can reduce the carbon footprint of incumbent recyclers by an average of 85% and also cut waste outputs by more than 90%.  Lead in the battery paste burden is converted into a lead organic salt, from which a range of nanostructured leady oxides are produced.  Optimised conditions have been developed for the production of nanostructured alpha-PbO; beta-PbO; Pb2O3 and Pb3O4.  These materials are typically produced with 10‒20% free-Pb, and the process is tailored to produce consistently the ratios of materials sought by the battery manufacturer.
