A method for electrochemical deposition of refined lithium metal to form a lithium anode in situ in a lithium (Li) ion battery comprising providing a fully lithiated cathode, providing a metal anode, providing a block copolymer electrolyte membrane between the cathode and the metal anode, and polarizing the cathode and the metal anode in the lithium ion battery to cause Li ions to migrate from the cathode through the block copolymer electrolyte and cause the electrochemical deposition to deposit refined lithium metal on the metal anode to form the lithium anode.
