Subproject 2: Diffusion pathways and activation energies in crystalline lithium ion conductors

Bild Subproject 2: Diffusion pathways and activation energies in crystalline lithium ion conductors

Analyses of the probability density functions and one particle potentials, determined by means of neutron diffraction, give information on diffusion pathways and activation energies. This is supported by quantum chemical calculations of the minimum energy path. Calculated spectroscopic parameters will corroborate experimental work on the characterization of the substances.
