제목 NASICON-type NaV2(PO4)3 as a cathode material for calcium-ion batteries
초록 The recent discovery of reversible plating and alloying of calcium has invoked considerable interest in calcium-based rechargeable batteries toward overcoming the limitations of conventional Li-ion batteries. Theoretical calculations also suggest that the development of cathode materials is anticipated. However, only a few cathode materials have been tested thus far, and these exhibit low energy-storage capability and poor cyclability. Herein, we report the highly reversible Ca-intercalation capability of NASICON-type NaV2(PO4)3, making it potential cathode material for nonaqueous Ca-ion batteries, with high capacity (90 mAh g−1) and voltage (~3.5 V), and good cyclability. These results demonstrate the feasibility of NaV2(PO4)3, as a highly reversible intercalation-type cathode material for calcium-ion batteries, and unveil the underlying intercalation mechanism.
