AbstractThe Delta H-f,298(theta) and Delta G(f,298)(theta) of cathode materials LiNi0.6Co0.2Mn0.2O2, LiNi0.5Co0.2Mn0.3O2, LiNi0.8Co0.1Mn0.1O2 and LiNi1/3Co1/3Mn1/3O2 for lithium ion power battery were estimated based on the group contribution method. The Delta H-f,298(theta) and Delta G(f,298)(theta) of 56 solid inorganic compounds were first estimated by the group contribution method. The absolute values of the relative errors were within 4% compared with the literature values. Mathematical models for estimating Delta H-f,298(theta) and Delta G(f,298)(theta) were constructed based on the group contribution method for estimating cathode material LiNixCoyMnzO2 for lithium ion power battery. By combining the XPS experimental data analyses, the values of the Delta H-f,298(theta) and Delta G(f,298)(theta) of ternary materials LiNi0.6Co0.2Mn0.2O2, LiNi0.5Co0.2Mn0.3O2, LiNi0.8Co0.1Mn0.1O2 and LiNi1/3Co1/3Mn1/3O2 are estimated to be -705.39 kJ.mol(-1), -703.90 kJ.mol(-1), -695.67 kJ.mol(-1), -705.17 kJ.mol(-1), and -647.98 kJ.mol(-1), -640.04 kJ.mol(-1), -631.10 kJ.mol(-1), -642.41 kJ.mol(-1), respectively.
