Preparation and characterization of nano-crystalline LiCoVO4 and LiNiVO4 used as cathodes for lithium ion batteries

Nano-crystalline LiCoVO4 and LiNiVO4 were prepared using Li2CO3, Co(NO3)2· 6H2O or Ni(NO3)2·6H2O and NH4VO3 as raw materials in deionized water and tartaric acid as a complexing reagent, and followed by 450-600°C calcination for 12 h. TGA showed weight loss due to the combustion of the precursor at...
