Abstract
Four different cathode materials, LiNiO₂, LiCoO₂, LiCo₀.₂ Ni₀.₈O₂ and LiCo₀.₄, Ni₀.₆O₂ were synthesized by sol - gel technique. The prepared materials were characterized X-ray diffraction pattern, FT-IR and cyclic voltammetry. X-ray diffraction pattern shows crystallinity of materials, increases with higher calcination temperature. From FT- IR studies, it was shown, that the purity of sample also increased with prolong heating at higher temperatures. It was possible to obtain pure and highly crystalline LiNiO₂ after heating for fourteen hours at 800°c. Cyclic voltammetry shows the four prepared materials are suitable for fabrication of cathode, as lithium ions can intercalate and de-intercalate. LiNiO₂ was used in battery fabrication. Charge / discharge characteristic curve was obtained.
