dc.description.abstractThe relatively large penetration depth, sensitivity to light elements, and non-destructive sample interaction afforded by neutron scattering is combined with instrumentation allowing fast data-acquisition times to allow neutron powder diffraction (NPO) to be a powerful tool for studying the structural variation of cathode and anode materials during battery cycling. In this study, a neutron-friendly battery comprised of a disordered LiNi0.5Mn1.5O4 (Fd3m) cathode, a Li4Ti5O12 anode, deuterated electrolyte, and the relatively low-hydrogen polyvinylidene difluoride separator was used to research a battery chemistry not yet commercially available. This work tracks crystallographic changes such as the variation of lattice parameters, lithium occupation, and oxygen positional parameters of the LiNi0.5Mn1.5O4 cathode and Li4Ti5O12} anode simultaneously with charge/discharge within a battery. Importantly, we find that the disordered LiNi0.5Mn1.5O4 cathode has a solid-solution reaction associated with its lattice change and the Ni2+/Ni3+ redox couple, and a two-phase reaction, between Li xNi0.5Mn1.5O4 and Ni0.25Mn0.75O2, that is related to the Ni3+/Ni4+ redox couple without a corresponding change in lattice. The details of these findings will be presented.en_US
