For the first time, we report a poly (2,2,6,6-tetramethylpiperidinyloxy-4-yl methacrylate) (PTMA)-based organic electrode with 100 wt% active material loading. The electrochemical performance of the PTMA electrode for organic batteries was improved by replacing the aluminum current collector by graphite ones. The use of graphite current collector reduces the cell weight and increases its mechanical flexibility. The resulting battery with the new carbon conductor- and binder-free organic electrode with polyimide-based gel polymer electrolyte (GPE) displayed significantly higher increased energy density (470 Wh kg(-1) vs. cell weight), which is essential for making organic batteries competitive with conventional Li ion batteries.
