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 ...
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 ...
