Sodium ion insertion in hollow carbon nanowires for battery applications.
Hollow carbon nanowires (HCNWs) were prepared through pyrolyzation of a hollow polyaniline nanowire precursor. The HCNWs used as anode material for Na-ion batteries deliver a high reversible capacity… Expand
Hierarchically porous graphene as a lithium-air battery electrode.
The lithium-air battery is one of the most promising technologies among various electrochemical energy storage systems. We demonstrate that a novel air electrode consisting of an unusual hierarchical… Expand
Self-assembled TiO2-graphene hybrid nanostructures for enhanced Li-ion insertion.
We used anionic sulfate surfactants to assist the stabilization of graphene in aqueous solutions and facilitate the self-assembly of in situ grown nanocrystalline TiO2, rutile and anatase, with… Expand
A Stable Vanadium Redox-Flow Battery with High Energy Density for Large-scale Energy Storage
The all-vanadium redox flow battery is a promising technology for large-scale renewable and grid energy storage, but is limited by the low energy density and poor stability of the vanadium… Expand
Reversible aqueous zinc/manganese oxide energy storage from conversion reactions
Rechargeable aqueous batteries are attractive owing to their relatively low cost and safety. Here the authors report an aqueous zinc/manganese oxide battery that operates via a conversion reaction… Expand
Ternary self-assembly of ordered metal oxide-graphene nanocomposites for electrochemical energy storage.
Surfactant or polymer directed self-assembly has been widely investigated to prepare nanostructured metal oxides, semiconductors, and polymers, but this approach is mostly limited to two-phase… Expand
Optimization of mesoporous carbon structures for lithium–sulfur battery applications
Mesoporous carbon (MC) with tunable pore sizes (22 nm, 12 nm, 7 nm, and 3 nm) and pore volumes (from 1.3 to 4.8 cm3 g−1) containing sulfur in the pores was studied as a mesoporous carbon–sulfur (MCS)… Expand
