Abstract

Abstract: The cathode material for lithium batteries Li(Co_x Al_1-x )O₂ has been synthesized by sol gel technique. The effects of sintering temperature, sintering time and the molar ratio of Al and Co on the phase behavior of material was investigated via X-ray diffraction. It is shown that the suitable synthetic and processing condition is that the sintering temperature is in the range of 600—900 ℃ and the sintering time is over 3 h.

Key words: Li battery, Cathode material, Sol-gel method, Synthesis, X-ray diffraction, Phase behavior
