Inhoud: Possibility of synthesizing LiNi1/3Co1/3Mn1/3O2 cathode via., soft chemistry based Gelatin Assisted Combustion [GAC] approach has been examined through the present study. GAC method with a calcination temperature as high as 750°C for a period of 24h. was found to be essential to prepare LiNi1/3Co1/3Mn1/3O2 powders with good hexagonal ordering and better cycling performance. The intensity ratio of (003) and (104) bragg peaks is greater than unity, which is an indication for the absence of cation mixing. The observed CV peaks confirm the presence of Ni, Co and Mn ions in their +3 oxidation state. A maximum discharge capacity of ~180mAh/g has been exhibited by the synthesized LiNi1/3Co1/3Mn1/3O2 cathode, when charged up to 4.6V. Hence, it is demonstrated that the LiNi1/3Co1/3Mn1/3O2 cathode synthesized through the present study could be exploited both as a high voltage and high capacity cathode material for use in rechargeable lithium battery applications.
