We request 5 days on Nimrod to determine the local environment of Li cations in a set of polyther solvents used as battery electrolytes. Through increasing the chain lengths of these polyethers, the so called Glymes, we hope to correlate their flexibility with coordination about Li in the solution phase. At present there only exists computational models of the lithium pair-distribution functions in these systems, and this study would thus represent the first experimental validation of existing models.
