Ni rich layered oxides are promising cathode materials for Li-ion batteries since they fulfil the energy density requirements of the automobile industry but they tend to degrade relatively fast. The magnetic and electronic properties of the materials have been under discussion since their discovery, though this knowledge is essential to understand their functionality and the reasons for failure upon long-term operation. Although previous powder neutron measurements have not detected any long range order in LiNiO2, a semi-disordered cluster model has been proposed based on high field magnetisation measurements. Here we propose to use the greater sensitivity of the Wish diffractometer combined with high quality single crystals to observe either magnetic diffraction from long range ordered moments or diffuse scattering from correlated magnetic ions.
