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 ...
Synthesis of single-crystalline LiMn2O4 and LiMn1.5Ni0.5O4 nanocrystals and their lithium storage properties
Yolk–shell spheres as nanoreactors: Single-crystalline LiMn2O4 and LiMn1.5Ni0.5O4 nanocrystals have been prepared by using yolk–shell spheres as nanoreactors to confine the size of the nanocrystals to a range of 14–19 nm ...
Carbon nanotube-encapsulated noble metal nanoparticle hybrid as a cathode material for Li-oxygen batteries
Although Li-oxygen batteries offer extremely high theoretical specific energy, their practical application still faces critical challenges. One of the main obstacles is the high charge overpotential caused by sluggish ...
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. ...
