The next generation of Li-ion rechargeable batteries is contingent on the development of new positive electrode materials with a greater capacity to store charge. Highly ordered layered structures have been universally considered the best candidate materials, however, recently this foundational understanding has been questioned in light of the discovery of several new Li-rich disordered rocksalt structure with even higher capacities. However, all of these materials suffer from substantial capacity decay over prolonged cycling which poses a critical barrier to their implementation. Due to the poor crystallinity of these structures (crystallites ~5 -10 nm in diameter) local probe techniques are essential to understand any structural changes, wherein it is suspected the root of the problem lies. With the ability to differentiate Li, Ni and Mn, neutron PDF is the ideal candidate technique.
