Abstract
A method for manufacturing an anode electrode for a battery cell includes providing a current collector; and forming a layer on the current collector to create a coated current collector. The layer includes one of a metal and a metal oxide that is not miscible in molten lithium. The method includes immersing the coated current collector in molten lithium to coat the coated current collector.
