A novel high-voltage cathode material Na6Fe5(SO4)8 (NFS) is successfully prepared for sodium-ion batteries for the first time. It is found that the NFS cathode shows a high working voltage of 3.7 V, together with an attractive energy density approaching 450 W h kg−1. And, based on an NFS@5%CNTs cathode and hard carbon (HC) anode, a full NFS@5%CNTs//HC cell can deliver an impressive energy density approaching 350 W h kg−1 and excellent cycling stability over 1000 cycles at 2C.

AbstractRechargeable solid-state sodium-ion batteries (SSSBs) hold great promise for safer and more energy-dense energy storage. However, the poor electrochemical stability between current sulfide-based solid electrolytes and high-voltage oxide cathodes has limited their long-term cycling performance and practicality. Here, we report the discovery of the ion conductor Na3-xY1-xZrxCl6 (NYZC) that is both electrochemically stable (up to 3.8 V vs. Na/Na+) and chemically compatible with oxide cathodes. Its high ionic conductivity of 6.6 × 10−5 S cm−1 at ambient temperature, several orders of magnitude higher than oxide coatings, is attributed to abundant Na vacancies and cooperative MCl6 rotation, resulting in an extremely low interfacial impedance. A SSSB comprising a NaCrO2 + NYZC composite cathode, Na3PS4 electrolyte, and Na-Sn anode exhibits an exceptional first-cycle Coulombic efficiency of 97.1% at room temperature and can cycle over 1000 cycles with 89.3% capacity retention at 40 °C. These findings highlight the immense potential of halides for SSSB applications.
