Abstract: In order to disclose the decomposition kinetics of charged LiMn(2)O(4) used in lithium-ion batteries, thermogravimetric analyzed (TGA) and C80 micro-calorimeter were employed in this study. Three stages of weight loss were detected by TG and two main exothermic processes were detected by C80 micro-calorimeter for the charged LiMn(2)O(4). The chemical reaction kinetics is supposed to fit by an Arrhenius law, and then the activation energy is calculated as E(a) = 90.4 and 140.1 kJ mol(-1) based on TG and C80 data, respectively. And the C80 method shows more advantages in (C) 2008 Elsevier B.V. All rights reserved.
