Layered lithiated transition metal oxides have been extensively developed and investigated as a cathode materials for lithium ion batteries due to the following advantages, such as high output voltage of 3.6 V, high energy density larger than 450Wh/dm3, low self-discharge rate less than 10%, no memory effect resulting in long cycle lives for more than 1000 times charging and discharging, free maintenance and no environmental pollution. The cathode materials in lithium ion battery are generally in the form of LiMO2 (M= Co, Ni, Mn, etc). Currently, lithium vanadium oxides also were studied. It is well known that the synthetic condition and methods are closely related to the electrochemical properties of lithium ion batteries. In this work, the wet chemical sol gel techniques have been used to synthesize LiNiO2 and LiV3O8. In this study, the LiNiO2 particles and LiV3O8 nanorods were successfully synthesized by sol-gel wet chemical methods. Annealing heat treatment influence the crystallinity of the final product, which may be consequently affected their electrochemical performance.
