Lu C.-H.Yeh P.-Y.Hsu W.-T.2019-05-132019-05-13200909258388https://scholars.lib.ntu.edu.tw/handle/123456789/407433The reaction kinetics of the formation of LiCoO 2 during solid-state reaction was investigated using a non-isothermal approach at constant heating rates. The conversion ratios of the starting material of LiCoO 2 were calculated from thermogravimetric measurements. Analysis based on the differential method revealed that two diffusion-controlled models described the probable reaction mechanisms. The utilized integral method corroborated the fact that the reaction kinetics of the formation of LiCoO 2 was governed by Ginstling's diffusion-controlled reaction model. The activation energy of the formation of LiCoO 2 was calculated to be 163.6 kJ/mol. A combination of the differential and integral methods was demonstrated to effectively elucidate the reaction kinetics of ceramics and accurately determine the associated kinetic parameters. ? 2008 Elsevier B.V.
