【 摘 要 】

A new aqueous Znâ€�?�NiCo₂O₄ rechargeable battery system with a high voltage, consisting of NiCo₂O₄ as cathode and metal Zn as anode, is proposed for the first time. It is cheap and environmental friendly, and its energy density is about 202.8 Wh kg^â€�??1. The system still maintains excellent capacity retention of about 85% after 100 full cycles at a current rate of 2 A g^â€�??1 between 1.5 and 1.95 V. This work not only provides a new battery system but also shows promise for application in large-scale energy storage for its low cost, good cycling and environmental friendliness.
