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 (m). 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.

Electrochemically recycling a lithium-ion battery

Examples are disclosed of methods to deactivate a lithium-containing battery. One example provides a method for discharging a lithium-containing battery, the method comprising adding the lithium-containing battery to a vessel, adding an oxidizing fluid to the vessel, adding carbon dioxide to the vessel, pressurizing the vessel, heating the vessel to form lithium carbonate within the lithium-containing battery, reducing heat and pressure in the vessel, and removing the battery from the vessel.
