Abstract

Read online

The authors report a sodium rich disordered birnessite cathode material Na0.27MnO2 for aqueous Na-ion storage. The impressive electrochemical performance is attributed to the co-deintercalation of structural water and Na-ion during the high potential charging process which stabilizes the layered structure.
