The synthesis and electrochemical characterization of polymers that bear galvinoxyles in the side chains is described. The monomers are synthesized employing C–C coupling reactions, polymerized with Rh(nbd)BPh 4 as a catalyst, and subsequently oxidized. These galvinoxyl‐containing polymers represent interesting anode materials for organic radical batteries and employ stable organic radicals, which are bound to polymers; hereby, metals and metal oxides, as active compounds, can be replaced. With the use of ethynylphenyl‐galvinoxyles as anode‐active material and poly(2,2,6,6‐tetramethylpiperidine‐ N ‐oxyl)methacrylate (PTMA) as cathode‐active material, metal‐free batteries with an aqueous and environment‐friendly electrolyte are built. These cells are tested for their charge and discharge capacities.
