Abstract:
Various embodiments relate to several processes that may recover commodity chemicals from an alkaline metal-air battery. In various embodiments, while the cell is operating, various side products and waste streams may be collected and processed to regain use or additional value. Various embodiments also include processes to be performed after the cell has been disassembled, and each of its electrodes have been separated such as not to be an electrical hazard. The alkaline metal battery recycling processes described herein may provide multiple forms of commodity iron, high purity transition metal ores, fluoropolymer dispersions, various carbons, commodity chemicals, and catalyst dispersions.
