dc.description.abstract | Herein, a new P2-type layered oxide is proposed as an outstanding intercalation cathode material for high energy density sodium-ion batteries (SIBs). On the basis of the stoichiometry of sodium and transition metals, the P2-type Na-0.55[Ni0.1Fe0.1Mn0.8]O-2 cathode is synthesized without impurities phase by partially substituting Ni and Fe into the Mn sites. The partial substitution results in a smoothing of the electrochemical charge/discharge profiles and thus greatly improves the battery performance. The P2-type Na-0.55[Ni0.1Fe0.1Mn0.8]O-2 cathode delivers an extremely high discharge capacity of 221.5 mAh g(-1) with a high average potential of approximate to 2.9 V (vs Na/Na+) for SIBs. In addition, the fast Na-ion transport in the P2-type Na-0.55[Ni0.1Fe0.1Mn0.8]O-2 cathode structure enables good power capability with an extremely high current density of 2400 mA g(-1) (full charge/discharge in 12 min) and long-term cycling stability with approximate to 80% capacity retention after 500 cycles at 600 mA g(-1). A combination of electrochemical profiles, in operando synchrotron X-ray diffraction analysis, and first-principles calculations are used to understand the overall Na storage mechanism of P2-type Na-0.55[Ni0.1Fe0.1Mn0.8]O-2. | en_US |
