Abstract: The thermal stability of lithium-ion battery cathode could substantially affect the safety of lithium-ion battery. In order to disclose the decomposition kinetics of charged LiCoO2 Used in lithium ion batteries, thermogavimetric analyzer (TG) and C80 micro-calorimeter were employed in this study. Four stages of mass losses were detected by TG and one main exothermic process was detected by C80 microcalorimeter for the charged LiCoO2. The chemical reaction kinetics is supposed to fit by an Arrhenius law, and then the activation energy is calculated as E-a=148.87 and 88.87 kJ mol(-1) based on TG and C80 data, respectively.
