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 2 O 4 nanowire electrode as the cathode. The NiCo 2 O 4 //Bi battery is able to deliver a remarkable energy density of 85.8 W h kg −1 at a power density of 1.02 kW kg −1 , and still retains 55.4 W h kg −1 when the power density is increased to 21.2 kW kg −1 .
