In this work, Ni(OH)(2) and (BiO)(4)CO3(OH)(2) microspheres are synthesized by solvothermal method. Then, a novel alkaline rechargeable Ni/Bi battery is assembled for the first time using the synthesized Ni(OH)(2) and (BiO)(4)CO3(OH)(2) as the positive electrode and negative electrode materials, respectively. As a result, the assembled Ni/Bi battery delivers a high specific capacity of 113 mAh g(-1) at a discharge rate of 0.2C based on the total mass of the electrode materials, as well as a high energy density of 92 Wh kg(-1) at a power density of 27.3 W kg(-1).
