MODERN APPROACHES TO CALCULATION OF THE PROPERTIES OF MATERIALS FOR ENERGY STORAGE A. Kabanov Samara State University The modern technologies demands to compact and effective rechargeable systems of energy storage. ... In this work we investigated the activation energies of one promising compound ­ Li2CoPO4F using combination of two methods ­ ab-initio and geometrical calculations. ... The nudged elastic band (NEB) method is adopted to find the kinetic energy barrier along diffusion pathways. ...
