Nanocrystalline Si

Nanocrystalline Si (c-Si) dispersed in amorphous Si (a-Si) encapsulating hard carbon (HC) has been synthesized as a new anode material for next generation lithium-ion batteries. An excellent cycle retention of 80% was exhibited for a HC@c-Si@a-Si/LiCoO2 full cell after 160 cycles at 1 C discharge/charge rate.

LiCoPO4 was prepared by a citric acid assisted sol-gel method and exploited as cathode material for lithium ion batteries. TG curve showed the appropriate temperature of the reaction and X-ray diffraction patterns indicated that LiCoPO4 synthesized at different temperatures was crystallized in an orthorhombic structure. During charge-discharge cycles, LiCoPO4 presented a plateaus of 4.8V corresponding to Co3+/Co2+ redox couples, and a discharge capacity of 126.3 mAh/g in the first cycle. The CV curve of LiCoPO4 showed that Li-ion diffusion in LiCoPO4 obeyed a different mechanism between charge and discharge processes.
