Studies of Nanophase LiCoO2 Synthesized by Solid State Reaction with Low Heating Temperature ( I )

Journal Article


Abstract


  • Nanophase LiCoO2 was synthesized by solid-state reaction with low heating temperature, i. e. the reactants Co(Ac)2 · 4H2O and LiOH · H2O in the appropriate molar ratio (1 : 1) were mixed and ground in agate mortar, then calcined. The samples obtained were characterized by XRD and IR methods. The phenomena during synthesizing are discussed by TG/TDA analysis, and the optimum temperature of heating was chosen. The BET and ICP results suggest that the sample has a large specific surface(54. 29 m2/g), a low quantity of impurity, thus it may be a good battery material. The nanophase -LiCoO2 samples produced have good cyclic performance and a higher working voltage plateau(3. 9 V).
