To develop the next generation of high performance Li-ion rechargeable batteries we need to find new positive electrode materials with a greater capacity to store charge. It is generally perceived that ordered layered structures are required for fast Li-ion diffusion and long term structural stability, however, results have shown that even in disordered materials, ionic mobility is facile and reversible and high capacities can be accessed. We have recently discovered several new materials in this space, however, despite the exciting electrochemical performance they exhibit, there is poor understanding of the phase purity and structure of these new materials which typically comprise nanoscale crystallites. We propose to use total neutron scattering to investigate the structure of these materials, which are highly disordered, to develop our understanding of their atomic-scale structure.
