ABSTRACT OF THE DISCLOSURE The present disclosure generally relates to battery anode structures with dielectric coating and methods of forming the same. In one implementation, a method of forming an anode structure is provided and includes exposing a material to be deposited on an anode positioned in a processing region to an evaporation process; flowing a reactive gas into the processing region; and reacting the reactive gas and the evaporated material to deposit a porous dielectric layer on at least a portion of the anode and form the anode structure. In another implementation, an anode electrode structure is provided and includes an anode containing at least one of lithium metal, lithium-alloy, or a mixture of lithium metal and lithium alloy; and at least one dielectric layer capable of conducting ions, wherein the at least one dielectric layer at least partially covers an anode surface and has a thickness of 1 to 2,000 nanometers.
