CNTs@SnO2@carbon coaxial nanocables with high mass fraction of SnO2 for improved lithium storage
The nanoCable Guy: Carbon nanotubes (CNTs)@SnO2@carbon have been fabricated using a simple procedure. The material exhibits greatly enhanced lithium-storage capacities and excellent cycling performance over extended cycles ...
Shape-controlled synthesis of cobalt-based nanocubes, nanodiscs, and nanoflowers and their comparative lithium-storage properties
Facile hydrothermal methods have been developed to synthesize large Co3O4 nanocubes, β-Co(OH)2 hexagonal nanodiscs and nanoflowers. Samples are thoroughly characterized by field-emission scanning electron microscopy, ...
Top-down fabrication of α-Fe2O3 single-crystal nanodiscs and microparticles with tunable porosity for largely improved lithium storage properties
In this work, we report a facile top-down approach to fabricate uniform single-crystal α-Fe2O3 nanodiscs via selective oxalic acid etching. Phosphate ions are employed as a capping agent to control the etching to along the ...
Building hematite nanostructures by oriented attachment
Getting bigger: Oriented attachment takes place among large hematite nanocrystals with a size over 100 nm to form 2D assemblies that further assemble into 3D superstructures through dipole–dipole interactions. Based on ...
SnO2 and TiO2 nanosheets for lithium-ion batteries
Recent developments in nanotechnology and materials science offer potential solutions to the questions of how to improve performance and safety, as well as enhance the reliability of lithium-ion batteries (LIBs): the ...
