ABSTRACTA microscopic mechanism for the structural phase transition from the orthorhombic mediate temperature (OMT) phase into the low temperature tetragonal (LTT) one is suggested on the basis of the cooperative pseudo Jahn-Teller effect. The local distortions mixing the ground and the first excited electronic states are ordered antiferrodistortively and are connected in part, with the oxygen octahedra rotations around the [100] axis. The results are in agreement, with the neutron scattering experiments data.

Jahn Teller Effect

The phase transition near room temperature in LiMn2O4 was studied as a function of the oxygen non-stoichiometry and as a function of the grain size of the cathode material and directly compared with its electrochemical performance.
