Abstract

Abstract : A new type of a sodium-ion full battery, consisting of a NaNi0.5 Ti0.5 O2 cathode and a pre-sodiated hard carbon anode, exhibiting higher capacity and coulombic efficiency is reported. Abstract : A new structure of sodium-ion full-cell with a layered NaNi0.5 Ti0.5 O2 cathode and a pre-sodiated hard carbon anode is reported. The pre-sodiation of the hard carbon anode, achieved via a facile approach in a three-electrode battery, can significantly enhance the initial coulombic efficiency of the sodium-ion full-cell. As a consequence, a much higher capacity is obtained in the hard carbon/NaNi0.5 Ti0.5 O2 sodium-ion battery. Based on the cathode mass, the full-cell with the pre-sodiated hard carbon anode can exhibit a reversible capacity of 93 mA h g −1 .
