Metal-air batteries are an important aspect of many beyond lithium ion research efforts. However, as our understanding of how molecular oxygen can act as a rechargeable cathode has progressed; the problems associated with how these materials at various states of charge interact with the lithium metal anode are only beginning to come to the surface. In this study we have devised a method to coat the surface a lithium with a functional group to act as either an anchor for further derivation studies or be polymerized to create a nanometer thick polymer coating attached to the surface by silane groups. These stable films, formed by polymerization of vinyl substituents, lower cell impedance at the electrode and over the first 50 cycles, increase cycling efficiency and demonstrate lower capacity fade.
