Abstract
Examples are disclosed that relate to methods and reactors for recycling a positive electrode material of a lithium-ion battery. One example provides a method of recycling a positive electrode material of a lithium-ion battery. The positive electrode material comprises a metal m having a n+ oxidation state (mn+). A reaction mixture is formed comprising the positive electrode material, an oxidizing agent, and lithium ions. The positive electrode material is electrochemically replenished with lithium via electrochemical reduction of the lithium ions while maintaining the n+ oxidation state of the metal m in the positive electrode material via the oxidizing agent.
