Title: A Fully Sodiated NaVOPO 4 with Layered Structure for High-Voltage and Long-Lifespan Sodium-Ion Batteries

Here, sodium-ion batteries are the primary candidate as a low-cost and resource-abundant alternative to lithium-ion batteries for large-scale electric storage applications. However, the development of sodium-ion batteries is hindered by the lack of suitable cathode materials that have sufficient specific energy density and cycle life. Herein, we report a cathode material, layered NaVOPO 4, which exhibits high voltage (~3.5 V vs. Na/Na +), high discharge capacity (144 mAh g -1 at 0.05 C), and remarkable cyclability with 67% capacity retention over 1000 cycles. The excellent performances result from the high Na + ion diffusion rate in the two-dimensional path and the reversible transformation behavior of (de)sodiation. Particularly, this layered structure and its synthetic procedure can be extended to other alkali-metal intercalation materials, leading to other metal ion battery systems, which opens a new avenue for large scale energy storage systems with development of high energy density and long-life cathodes for electric storage applications.
