Graphite prelithiation by solid electrochemical corrosion of lithium metal with a superficial mosaic structure

A transformative concept of solid electrochemical corrosion has been put forward, in which solid-state electrolyte LiPON has been applied to replace the liquid one to prelithiate graphite with Li-metal. Thus, high prelithiation efficiency and low polarization of the treated anode can be obtained, wi...

Summary:A transformative concept of solid electrochemical corrosion has been put forward, in which solid-state electrolyte LiPON has been applied to replace the liquid one to prelithiate graphite with Li-metal. Thus, high prelithiation efficiency and low polarization of the treated anode can be obtained, with a unique mosaic structure left at the surface. Prelithiation by solid electrochemical corrosion of lithium metal has been created with a graphite surface being modified by a mosaic structure.
