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 ...
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. ...
Synthesis of porous amorphous FePO4 nanotubes and their lithium storage properties
Holey pipes: An oil-phase chemical route was used to prepare porous amorphous a-FePO4 nanotubes. In the etching process, Fe2O3 reacted with weak acid, resulting in nanotubes with a pore size of 2–10 nm. The porous nanotubes ...
Sulfonated poly (ether ether ketone)-based proton exchange membranes for vanadium redox battery applications
Low cost sulfonated poly (ether ether ketone) membranes have been successfully prepared and optimized at various sulfonation conditions by casting method for vanadium redox battery applications. The optimized SPEEK membrane ...
