Abstract
A new type of ultrafast Ni//Bi battery with high flexibility and impressive electrochemical performance is demonstrated for the first time based on an as-prepared Bi electrode as the anode and a NiCo<sub>2</sub> O<sub>4</sub> nanowire electrode as the cathode. The NiCo<sub>2</sub> O<sub>4</sub> //Bi battery is able to deliver a remarkable energy density of 85.8 W h kg<sup>-1</sup> at a power density of 1.02 kW kg<sup>-1</sup> , and still retains 55.4 W h kg<sup>-1</sup> when the power density is increased to 21.2 kW kg<sup>-1</sup> .
