Facile preparation of hydrated vanadium pentoxide nanobelts based bulky paper as flexible binder-free cathodes for high-performance lithium ion batteries
Hydrated vanadium pentoxide (V2O5•0.44H2O, HVO) nanobelts were synthesized by a simply high-yield (e.g. up to ~99%) hydrothermal approach. The length of these nanobelts was up to several hundred ...
Vanadium pentoxide cathode materials for high-performance lithium-ion batteries enabled by a hierarchical nanoflower structure via an electrochemical process
Hierarchical vanadium oxide nanoflowers (V10O24·nH2O) were synthesized via a simple, high throughput method employing a fast electrochemical reaction of vanadium foil in NaCl aqueous solution, followed by an aging treatment ...
Template-free synthesis of urchin-like Co3O4 hollow spheres with good lithium storage properties
Hierarchical urchin-like hollow spheres (5–8 μm in diameter) assembled by one-dimensional nanowires consisting of many interconnected Co3O4 nanoparticles (10–50 nm) are successfully synthesized. Co(CO3)0.5(OH)·0.11H2O ...
Synthesis of hexagonal-symmetry α-iron oxyhydroxide crystals using reduced graphene oxide as a surfactant and their Li storage properties
Microcrystalline α-iron oxyhydroxide/reduced graphene oxide (α-FeOOH/rGO) samples have been successfully synthesized by a facile hydrothermal process. The α-FeOOH/rGO samples are either hexagonal disks with a diameter of ...
Ultrathin V2O5 nanosheet cathodes : realizing ultrafast reversible lithium storage
Few-layer V2O5 nanosheets with a thickness of 2.1–3.8 nm have been successfully synthesized in this work via a simple and scalable liquid exfoliation technique. The unique nanostructure allows the high-rate transportation ...
Controlled synthesis of double-wall a-FePO4 nanotubes and their LIB cathode properties
Double-wall amorphous FePO4 nanotubes are prepared by an oil-phase chemical route. The inward diffusion of vacancies and outward diffusion of ions through passivation layers result in double-wall nanotubes with thin walls. ...
