Designed synthesis of coaxial SnO2@carbon hollow nanospheres for highly reversible lithium storage
A proof-of-concept structural design is demonstrated for high-capacity lithium-ion batteries anode materials by multistep synthesis of coaxial SnO2@carbon hollow nanospheres. This material integrates two beneficial features: ...
Fabrication of core−shell structure of M@C (M=Se, Au, Ag2Se) and transformation to yolk−shell structure by electron beam irradiation or vacuum annealing
Selenium @ carbon core−shell spheres have been synthesized via a simple one-step hydrothermal carbonization process using sucrose and sodium selenite as precursors. Metal selenide or noble metal, e.g. Ag2Se or Au, can be ...
Anatase TiO2 nanosheet : an ideal host structure for fast and efficient lithium insertion/extraction
Anatase TiO2 nanosheets with largely exposed (0 0 1) facets have been synthesized by a modified method. Exploitation of these nanosheets as a host structure for reversible lithium insertion/extraction has been investigated. ...
SnO2 nanoparticles with controlled carbon nanocoating as high-capacity anode materials for lithium-ion batteries
We demonstrate a facile route for the scalable synthesis of SnO2 nanoparticles with controlled carbon nanocoating for use as high-capacity anode materials for next-generation lithium-ion batteries. SnO2 nanoparticles with ...
The superior lithium storage capabilities of ultra-fine rutile TiO2 nanoparticles
The lithium storage capabilities of ultra-fine rutile TiO2 nanoparticles have been studied. Ultra-fine rutile TiO2 nanoparticles with only several nanometers in size have been prepared by a modified wet-chemical method ...
One-pot synthesis of carbon-coated SnO2 nanocolloids with improved reversible lithium storage properties
We report a simple glucose-mediated hydrothermal method for gram-scale synthesis of nearly monodisperse hybrid SnO2 nanoparticles. Glucose is found to play the dual role of facilitating rapid precipitation of polycrystalline ...
