A process for extracting, recovering and recycling metals and materials from spent lithium ion batteries (LIB) that comprises the contacting battery waste products with a deep eutectic solvent, and leaching the metal from the battery waste product and extracting the metal into the deep eutectic solvent with heat and agitation. After the leaching and extracting, the process further includes recovering the dissolved metals ions from the deep eutectic solvent solution, followed by a step of regeneration of cathode materials.

Recycling Li-ion batteries using green chemicals and processes

An energy storage device including a first electrode comprising lithium, a second electrode comprising a metal diboride, an electrolyte disposed between the first electrode and the second electrode and providing a conductive pathway for lithium ions to move to and from the first electrode and the second electrode, and a separator within the electrolyte and between the first electrode and the second electrode. A method of forming an energy storage device including forming a first electrode to include lithium, forming a second electrode to include a metal diboride, disposing an electrolyte between the first electrode and the second electrode, the electrolyte providing a conductive pathway for lithium ions to move to and from the first electrode and the second electrode, and disposing a separator within the electrolyte and between the first electrode and the second electrode.
