One-step electrochemical preparation of graphene-based heterostructures for Li storage
We report a facile method to prepare nanoarchitectured metal oxides/graphene hybrids as both positive and negative electrodes for Li-ion batteries. The metal oxides/graphene hybrids were synthesized by deposition of metal ...
Ultrathin V2O5 nanosheet cathodes : realizing ultrafast reversible lithium storage
Few-layer V2O5 nanosheets with a thickness of 2.1–3.8 nm have been successfully synthesized in this work via a simple and scalable liquid exfoliation technique. The unique nanostructure allows the high-rate transportation ...
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. ...
Binder-free graphene foams for O2 electrodes of Li-O2 batteries
We report a novel method to prepare bind-free graphene foams as O2 electrodes for Li–O2 batteries. The graphene foams are synthesized by electrochemical leavening of the graphite papers, followed by annealing in inert gas ...
Controlled synthesis of double-wall a-FePO4 nanotubes and their LIB cathode properties
Double-wall amorphous FePO4 nanotubes are prepared by an oil-phase chemical route. The inward diffusion of vacancies and outward diffusion of ions through passivation layers result in double-wall nanotubes with thin walls. ...
