• nano-crystalline LiCoVO4
• solvothermal reaction
• isopropanol

(LiOHH2O)-H-., CO(NOo)(2)(.)6H(2)0 and NH4VO3 were used to prepare nano-crystalline LiCOVO4 by 150 degrees C solvothermal reaction in isopropanol for 10-360 h and subsequent calcination at 300-500 degrees C for 6 h. XRD, TEM and selected area electron diffraction (SAED) revealed the presence of nano-crystalline LiCoVO4 with inverse spinel structure. The V-O stretching vibration modes Of VO4 tetrahedrons were detected by FTIR over the range 617-835 cm(-1) and by Raman spectrometer at 805.7 and 783.1 cm(-1). Co, V and O were detected by EDX. TGA of solvothermal products shows weight loss due to the evaporation and decomposition processes at 40-648 degrees C.
