Solvation structure of [Li.sup.+] in concentrated LiP[F.sub.6]-propylene carbonate solutions

Article Abstract:

The results of time-of-flight (TOF) neutron diffraction measurements on 10 mol % LiP[F.sub.6] solutions in deuterated propylene carbonate (PC) in which the [Li.sup.6] / [Li.sup.7] isotope ratio is changed, is described. The first solvation shell of [Li.sup.+] is found to consist in average of 4.5 PC molecules with an intermolecular [Li.sup.+]...O(PC) distance of 2.04(1) angstrom.

Structured modifications between lithium-diborate glasses and melts: Implications for transport properties and melt fragility

Article Abstract:

The effect of temperature on the alkali environment in melts and in glasses is studied in lithium diborate system by neutron diffraction with isotropic substitution of Li. It is reported that clear defined structural modifications between borate glasses and melts are observed.

Phonons and thermodynamics of unmixed and disordered Li0.6FePO4

Article Abstract:

A study on the lithium-storage material Li0.6FePO4 is conducted by inelastic neutron scattering and differential scanning calorimetry. Li0.6FePO4 is found to undergo a transformation from a two-phase mixture to a disordered solid-solution at 200 degree Celsius.
