Assorted Phenoxyl‐Radical Polymers and Their Application in Lithium‐Organic Batteries. Issue 8 (3rd March 2016) - Jähnert, Thomas
Abstract : The synthesis and electrochemical characterization of novel polymers bearing phenoxyl‐radicals as redox‐active side chains is described. The monomers are synthesized from the corresponding phenols and quinones, respectively. These compounds are subsequently polymerized via ring‐opening metathesis polymerization. The electrochemical properties of the phenoxyl‐radical polymers are characterized using cyclic voltammetry and the most promising polymer is investigated as active material in a lithium coin‐cell, creating the first phenoxyl‐lithium battery. These phenoxyl‐containing polymers represent interesting anode materials for organic radical and lithium batteries due to their suitable redox‐potentials and possibility to create batteries with higher potentials as well as straightforward synthesis procedures.

These batteries are tested for their charge‐ and discharge‐behavior and showed promising results.
