TiO2 nanocrystals/graphene hybrids with enhanced Li-ion storage performance

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 graphene. These nanostructured TiO2-graphene hybrid materials were used for investigation of Li-ion insertion properties. The hybrid materials showed significantly enhanced Li-ion insertion/extraction in...

TiO2 and SnO2@TiO2 hollow spheres assembled from anatase TiO2 nanosheets with enhanced lithium storage properties.

TiO(2) and SnO(2)@TiO(2) hollow spheres assembled from anatase TiO(2) nanosheets with exposed (001) high-energy facets are constructed via a templating approach, and the as-prepared samples exhibit enhanced lithium storage properties.

Tin Nanoparticles Encapsulated in Hollow TIO2 Spheres as High Performance Anode Materials for Li-Ion Batteries

Surface Engineering and Design Strategy for Surface‐Amorphized TiO2@Graphene Hybrids for High Power Li‐Ion Battery Electrodes

Surface amorphization provides unprecedented opportunities for altering and tuning material properties. Surface-amorphized TiO2@graphene synthesized using a designed low temperature-phase transformation technique exhibits significantly improved rate capability compared to well-crystallized TiO2@graphene and bare TiO2 electrodes. These improvements facilitates lithium-ion transport in both inser...

3D Scaffolded Nickel-Tin Li-Ion Anodes with Enhanced Cyclability.

A 3D mechanically stable scaffold is shown to accommodate the volume change of a high-specific-capacity nickel-tin nanocomposite during operation as a Li-ion battery anode. The nickel-tin anode is supported by an electrochemically inactive conductive scaffold with an engineered free volume and controlled characteristic dimensions, which engender the electrode with significantly improved cyclabi...
