摘要:
The nanoscale mechanisms of ion deintercalation in battery cathode materials remain poorly understood, especially the relationship between crystallographic defects (dislocations, small angle grain boundaries, vacancies, etc ), device performance, and durability. In this work, operando scanning X-ray diffraction microscopy (SXDM) and multi-crystal X-ray diffraction (MCXD) are used to investigate microstrain and lattice tilt inhomogeneities inside Li 1 − x Ni 0.5 Mn 1.5 O 4 cathode particles during electrochemical cycling and their influence on ...
