A facile approach to nanoarchitectured three-dimensional graphene-based Li–Mn–O composite as high-power cathodes for Li-ion batteries
We report a facile method to prepare a nanoarchitectured lithium manganate/graphene (LMO/G) hybrid as a positive electrode for Li-ion batteries. The Mn2O3/graphene hybrid is synthesized by exfoliation of graphene sheets ...
One-step solvothermal synthesis of single-crystalline TiOF2 nanotubes with high Lithium-ion battery performance
Single-crystalline TiOF2 nanotubes were prepared by a one-step solvothermal method. The nanotubes are rectangular in shape with a length of 2–3 μm, width of 200–300 nm, and wall thickness of 40–60 nm. The formation of TiOF2 ...
Fe2O3 nanocluster-decorated graphene as O2 electrode for high energy Li–O2 batteries
Fe2O3 nanocluster-decorated graphene (Fe2O3/graphene) hybrids with controlled contents of Fe2O3 were prepared by a facile electrochemical process. These Fe2O3/graphene hybrids were tested as O2 electrodes for Li–O2 batteries, ...
Controlled soft-template synthesis of ultrathin C@FeS nanosheets with high-Li-storage performance
We report a facile approach to prepare carbon-coated troilite FeS (C@FeS) nanosheets via surfactant-assisted solution-based synthesis. 1-Dodecanethiol is used as both the sulfur source and the surfactant, which may form ...
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 ...
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 ...
