Abstract: Li-ion batteries are one of the most extensively studied energy storage devices in the world today. These batteries are found in mobile phones and laptop computers, but future applications may include electric vehicles and energy storage systems for smart electricity grids based on renewable intermittent power generation sources, promising to fundamentally change how we live. The in-depth understanding of the processes occurring in Li-ion batteries is crucial for further development of these technologies. Neutron diffraction to study components within Li-ion batteries has distinct advantages. These include high sensitivity towards Li and a large penetration depth for bulk analysis of real-life Li-ion batteries. This talk will highlight recent results from in-situ [1] and ex-situ neutron diffraction studies of electrode materials in Li-ion batteries. In particular, the simultaneous tracking of lattice parameters of graphite anodes and LiCoO2 cathodes in commercial Li-ion batteries, development of specialised batteries for in-situ experimentation, crystal-structure investigations of Li-insertion, and the elucidation of structure-property relationships of electrodes in Li-ion batteries. This work is aimed at providing a real-time understanding of critical structural processes occurring at the electrodes and highlights the insights obtainable by marrying together neutron-diffraction with electrochemistry.
