Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: decommissioning an electrochemical system; and converting at least one portion of a metal electrode of the electrochemical system into a commodity metal source, wherein converting the at least one portion of the metal electrode into the commodity metal source includes pumping an organic solvent into the electrochemical system, where the organic solvent causes an exothermic reaction used for heat in an energy plant and produces the commodity metal source including a metal oxide with crystalline features and uniform composition. 2. The method of claim 1 , wherein the commodity metal source comprises iron. 3. The method of claim 2 , wherein the commodity metal source comprises direct reduced iron (DRI). 4. The method of claim 1 , further comprising using another portion of the metal electrode to form metal-based concrete.
