摘要: Abstract Lithium cobaltite LiCoO2 was prepared by solid state route and characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), magnetic properties measurement simultaneous thermal analysis (STA). The heat capacity enthalpy increments were measured physical property system (PPMS), differential calorimetry (DSC) drop calorimetry. oxygen non-stoichiometry determined thermogravimetric (TG). Above room temperature the dependence of molar derived least squares method from DSC data. also analyzed in terms a combined Debye–Einstein model. entropy evaluated low
