Template-free synthesis of urchin-like Co3O4 hollow spheres with good lithium storage properties

Rui, Xianhong; Tan, Huiteng; Sim, Daohao; Liu, Weiling; Xu, Chen; Hng, Huey Hoon; Yazami, Rachid; Lim, Tuti Mariana; Yan, Qingyu (2013)

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 ...

Controlled synthesis of double-wall a-FePO4 nanotubes and their LIB cathode properties

Cai, Ren; Liu, Hai; Zhang, Wenyu; Tan, Huiteng; Yang, Dan; Huang, Yizhong; Hng, Huey Hoon; Lim, Tuti Mariana; Yan, Qingyu (2013)

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 cobalt phosphides and their application as anodes for lithium ion batteries

Yang, Dan; Zhu, Jixin; Rui, Xianhong; Tan, Huiteng; Cai, Ren; Hoster, Harry E.; Yu, Denis Yau Wai; Hng, Huey Hoon; Yan, Qingyu (2013)

A facile thermal decomposing method has been developed for the fabrication of CoxP nanostructures with controlled size, phase, and shape (e.g., Co2P rod and spheres, CoP hollow and solid particles). An amorphous carbon ...

Synthesis of single-crystalline LiMn2O4 and LiMn1.5Ni0.5O4 nanocrystals and their lithium storage properties

Lu, Ziyang; Rui, Xianhong; Tan, Huiteng; Zhang, Wenyu; Hng, Huey Hoon; Yan, Qingyu (2013)

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 ...
