Abstract
Aided by advanced electron microscopy, the authors imaged dissociated dislocations in Li2MnO3 during an initial charge to 5 V. Such defects possess high gliding and transverse mobility and prompt O2 release. This work provides fresh insights into the defect chemistry of cathode materials for batteries.
