The enthalpy of formation of Li 2 MnO 3 was measured by high temperature oxide solution calorimetry in a sodium molybdate solvent and the heat capacity of the compound was determined using differential scanning calorimetry. The enthalpy of formation of Li 2 MnO 3 from the elements is slightly less exothermic than that of the orthorhombic and monoclinic modifications of LiMnO 2 but more exothermic than that of LiNiO 2 , LiCoO 2 , the LiNi 1¹x Co x O 2 solid solutions and the Li 1+x Mn 2¹x O 4 spinels. The heat capacity of Li 2 MnO 3 is also slightly lower than the estimated heat capacity based on stoichiometric amounts of Li 2 O and MnO 2 according to the Neumann-Kopp approximation. The slight differences in heat capacities are attributed to the differences in the bonding environments of Li + ions in Li 2 MnO 3 and the constituent binary oxide Li 2 O. The thermochemical data presented here are essential for the advanced thermodynamic modeling of multicomponent electrode materials based on the promising xLi 2 MnO 3 ·(1 ¹ x)LiMO 2 nano-composite cathode system.
