Pompon-like MnO2 and N/O doped nanoporous carbon composites with an ultrahigh capacity for energy storage

Porous carbon materials and metal oxides are the most favorite electrode materials for supercapacitors. Herein, we put forward a novel biomass-derived carbon and metal oxide composite which denoted as [email protected]2 (activated ganoderma lucidum spore-derived O and N co-doped nanoporous carbon and pompon-like MnO2 composite). When tested as electrode material, [email protected]2 exhibits an excellent capacity of 1324 F g−1 at 1 A g−1 in a...
