Lithium ion distribution in lithium-rich lithium manganese polyphosphate electrode glasses for lithium batteries

The present proposal seeks to establish the conductivity mechanism in a series of lithium manganese polyphosphate glasses rich in lithium for potential use in all solid state lithium ion batteries. Lithium ion distribution and the role of manganese will be investigated by a combination of neutron and X-ray scattering data analysis. Data will be analysed to reveal short range correlations and average coordination numbers. Key to establishing the conductivity mechanism is direct investigation of the Li-Li correlations. These will be examined by appropriate subtraction of data obtained from null-Li containing. Energy minimised structural models will be constructed for use as starting models for Reverse Monte Carlo fitting of the real space and reciprocal space data to reveal detail of the longer range correlations.
