In this proposal cathode materials required for the target-oriented development of so-called high-energy density 4 V cathodes in lithium-ion batteries [1] are in the focus of interest. For this exploratory experiment, taking into consideration the various ways of sharing the structural basic building units (transition metal octahedra), we propose to measure the NCS (neutron Compton scattering) kinetic energies of the atoms Li and F of:(a) Li3TiF6 (cryolithe type), isolated TiF6-octahedra (b) Li2TiF6 (trirutile type), corner- and edge-shared TiF6-octahedra (c) LixTiF3 (x < 1; derived from the ReO3 type), completely corner-shared TiF6-octahedra It should be noted that theses materials, and similar of the same type, are presently under consideration for realistic industrial applications. New fundamental chemical insights are expected.
