Local Structure Study of Nanosized High Nickel-Content Li-ion Cathode Materials

Abstract: Li ion batteries currently use LiCoO2 based materials as the cathode. The cost and scarcity of cobalt have driven a search for alternative materials and a leading candidate involves replacing cobalt with a nickel-rich mixture to give Li(Ni0.8Mn0.1Co0.1)O2. This gives improved energy density but the cathode becomes unstable and leads to battery degradation with repeated cycling. By reducing particle size to 200nm, we have produced material that maintains battery performance without the degradation problems of conventional, bulk material. We will use total neutron scattering to identify the structural differences that result from nanostructuring the material, and also examine the effect of the protective Al2O3 coating on the NMC-811 material. This will give us insights into the cation distribution, and the lithium ordering in this next generation battery material.
