Stoichiometry matters: correlation between antisite defects, microstructure and magnetic behavior in the cathode material Li 1− z Ni 1+ z O 2

Using synchrotron X-ray and neutron diffraction, NMR and magnetometry techniques, this study reveals how point defects evolve and critically affect particle growth and magnetic properties in the cathode material Li 1− z Ni 1+ z O 2 (−0.05 ≤ z ≤ 0.35).
