In situpolymerized synthesis of MnO nanoparticles anchored on N,S co-doped carbon as efficient cathodes for quasi-solid-state zinc ion batteries

MnO nanoparticles confined in N,S co-doped porous C are prepared by employing acrylamide monomers as the chelating agents and carbon source. When serving as a zinc-ion battery cathode, it can exhibit enhanced rate performance and a long lifespan.
