Synthesis and electrochemical performance lithium cobalt oxide as cathode materials of lithium-ion battery

Liquid-feed flame spray pyrolysis (LF-FSP) has emerged as a promising technique for producing wide range of single or multicomponent nanomaterials. Using this technique, severalnanostructured lithium ion battery (LIB) materials have been produced. Herein, we report LFFSP synthesis of nanostructured LiCoO2 as LIB cathode active material. Molar ratios of lithium: cobalt in the precursor solution was altered at three different levels, viz., 1:1, 1.3:1 and 1.7:1.Charge-discharge and cyclic voltammetric studies showed that performance of the LiCoO2 sample synthesized at ratio of 1.7:1 was superior based on a high capacity of 126 mAh g-1 at 0.1 C in the first cycle and a reversible capacity of 103 mAh g-1 at 0.1 C in the 3th cycle
