Abstract

Nanocrystalline LiNi~1/3~Co~1/3~Mn~1/3~O~2~ was synthesized by a sol–gel method. Thermal history of the gel was analyzed by thermogravimetric (TG) analysis and differential thermal analysis (DTA). Powders X‐ray diffraction (XRD) proved the formation of layered α‐NaFeO~2~ hexagonal lattice. Scanning electron microscopy (SEM) showed that original particles were of the size range of 200–300 nm. The discharge capacity was 183 mAh/g in the first cycle with 87.5% capacity retention in 30 cycles at C/10 rate in 3.0–4.5 V potential range.
