Facile preparation of hydrated vanadium pentoxide nanobelts based bulky paper as flexible binder-free cathodes for high-performance lithium ion batteries
Hydrated vanadium pentoxide (V2O5•0.44H2O, HVO) nanobelts were synthesized by a simply high-yield (e.g. up to ~99%) hydrothermal approach. The length of these nanobelts was up to several hundred ...
Cobalt oxide nanowall arrays on reduced graphene oxide sheets with controlled phase, grain size, and porosity for Li-ion battery electrodes
A facile chemical approach has been developed to produce nanohybrids with ultrathin Co oxides nanowall arrays on reduced graphene oxide (rGO) sheets. The Co oxides exhibited porous structure. The porosity of the Co oxide/rGO ...
Achieving high specific charge capacitances in Fe3O4/reduced graphene oxide nanocomposites
We report a facile approach to synthesize nanocomposites with Fe3O4 nanopaticles (NPs) attached to reduced graphene oxide (rGO) sheets by a solvothermal process, which combines the growth of Fe3O4 NPs and the ...
Synergetic approach to achieve enhanced lithium ion storage performance in ternary phased SnO2–Fe2O3/rGO composite nanostructures
We report here a study on the Li ion storage performance of binary phased SnO2/rGO and ternary phased SnO2–Fe2O3/rGO composite nanostructures. The SnO2/rGO and SnO2–Fe2O3/rGO were prepared by a facile wet-chemical approach. ...
Facile synthesis of metal oxide/reduced graphene oxide hybrids with high lithium storage capacity and stable cyclability
We report an environment-friendly approach to synthesize transition metal oxide nanoparticles (NPs)/ reduced graphene oxide (rGO) sheets hybrids by combining the reduction of graphene oxide (GO) with the growth of ...
