Dynamic imaging of crystalline defects in lithium-manganese oxide electrodes during electrochemical activation to high voltage

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 batteri...
