ABSTRACT:
An electrolytic cell and electrolytic process wherein the cell includes a metal anode (such as a lithium anode), a cathode and an electrolyte. A surface layer which is applied to the metal anode enables transfer of ions from the metal anode to the electrolyte and thus allows the ions to pass back into contact with the metal anode. The surface layer is also electronically conductive so that the ions will be uniformally attracted back onto the metal anode during electrodeposition to, in turn, substantially suppress dendrite growth and, in turn, substantially increase the cycle life of the cell.
