Calcium-ion batteries (CIBs) are gaining increasing attention due to their theoretically high capacity, owing to the divalency of calcium, and low cost. However, only a few calcium insertion electrode materials are reported, and most of them exhibit low capacity or poor cyclability in nonaqueous electrolytes. Herein, we demonstrated high-performance calcium molybdenum bronze Ca0.13MoO3 center dot(H2O)(0.)(41) as a potential CIB cathode material at room temperature, with a reversible discharge capacity of 192 mAh g(-1) at 86 mA g(-1)(,) an average voltage of 2.4 V (vs Ca/Ca2+), and excellent cyclability. This work provides the feasibility of developing high-capacity CIB cathode materials.
