Core-shell nanostructured organic redox polymer cathodes with superior performance

Core-shell nanoparticles stabilized by a cationic surfactant are prepared from the poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl methacrylate) redox polymer. The nanoparticles are further self-assembled with negatively charged reduced graphene oxide nanosheets and negatively charged multi-walled carbon nanotubes. This results in the formation of a free-standing cathode with a layered nanostructure and a high content of redox polymer that exhibits 100% utilization of the active substance with a measured capacity as high as 105 mAh/g based on the whole weight of the electrode.
