1. A reactive polymer composite comprising a reactive functionalized polymer having a main polymer chain with functionalization along the main polymer chain, wherein the functionalization comprises one or more functional groups that are configured to react with a metal electrode to form a polymeric metal salt and one or more functional groups configured to electrochemically decompose to generate a stable solid electrolyte interphase (SEI) layer on the metal electrode.
