Research output: Patent


A method (2800) of selectively leaching one or more manganese-containing phases from a mixed-phase battery electrode material comprises treating (2802) the mixed-phase battery electrode material with a solution of an acid, the acid acting as both a leaching agent and a reducing agent, so as to form a manganese-containing leachate whilst leaving at least one phase of the battery electrode material unleached, wherein the acid has a pKa greater than or equal to -2. Either or both of the leachate and the remaining electrode material may then be regenerated (2806, 2808)
