This paper reports a newly developed method for the shape and size control of transition metal composite oxides, such as LiVMoO6, to obtain significantly enhanced electrode properties lithium-ion batteries. Rod-like LiVMoO6 nanocrystals were synthesized through designed route partial reduction, self-assembly re-oxidation. V5+ Mo6+ ions used with low-grade starting materials get mixed valence V Mo. It is believed that ion pairs V5+/V4+ or Mo6+/Mo5+ in resultant mixture play an important role...

Composite metal hydroxide Ni0.5Co0.2Mn0.3(OH)2has been prepared via a co-precipitation reaction method.The obtained powders show single phase with typical hexagonal of β-Ni(OH)2.SEM reveals that the irregular secondary Ni0.5Co0.2Mn0.3(OH)2particles were formed at initial stage and particles changed gradually into spherical increase in time.The LiNi0.5Co0.2Mn0.3O2cathode, synthesized using as-prepared Ni0.5Co0.2Mn0.3(OH)2as precursor, has an discharge capacity 162.4 mAh g-1 still keeps 156.3...
Nano silver materials were prepared by using PVP as dispersant and hydrazine hydrate reducing agent under the protection of inert gas.Nano with different particle sizes morphologies obtained controlling concentration AgNO3.Different shapes nanoparticles have UV Vis absorption spectra.The method is simple in operation, short reaction time, requiring less equipment low preparation cost, can be synthesized one step mild conditions.
LiFePO 4 @C/G composite is successfully prepared by a simple spray drying and subsequent high temperature calcination reaction. Two different ferric sources, nitrate citrate, are used together to tune the pH of solution carbon content product. As-prepared single-phase with orthorhombic olivine-type structure. SEM TEM reveal that composed regularly spherical secondary aggregations particle size several micrometers. In aggregation, nano-crystallites homogeneously thoroughly coated layer...
