Free-standing electrodes with high gravimetric/volumetric capacitance will open up potential applications in miniaturized consumer electronics. Herein, we report a simple synthesis technology of free-standing orthorhombic Nb2O5 (T-Nb2O5)/graphene composite papers for Li-intercalating pseudocapacitive electrodes. Through facile polyol-mediated solvothermal reaction, the nanodots are homogeneously decorated onto surface reduced graphite oxide (rGO), which can form homogeneous Nb2O5/rGO...

Nitrogen-enriched mesoporous carbons with tunable nitrogen content and similar structures have been prepared by a facile colloid silica nanocasting to house sulfur for lithium-sulfur batteries. The results give unequivocal proof that doping could assist carbon suppress the shuttling phenomenon, possibly via an enhanced surface interaction between basic functionalities polysulfide species. However, only within appropriate level can improve electronic conductivity of matrix. Thus, dependence...
