Abstract
Embodiments are disclosed herein that relate to recycling and refurbishing battery electrode materials. For example, one disclosed embodiment provides a method comprising obtaining a quantity of spent electrode material, reacting the spent electrode material with an aqueous lithium solution in an autoclave while heating the spent electrode material and the aqueous lithium solution to form a hydrothermally reacted spent electrode material, removing the hydrothermally reacted spent electrode material from the aqueous lithium solution, and sintering the hydrothermally reacted spent material to form a recycled electrode material.
