Abstract

The Ni oxidation state in Li_1−xNi_0.5Mn_1.5O₄ within a composite electrode mapped by scanning transmission X-ray microscopy (STXM) has shown unexpected variations in phase separation among and within individual battery particles, which has been experimentally correlated to both their morphology and interface structure.
