摘要

报道了一种利用锌阳极、硫酸锌水溶液电解质和对苯二酚(QH2)阴极的高可充电电池。固定在微孔碳孔内的QH2具有较高的比容量(0.5℃时为482 mA h g-1),接近QH2的理论比容量(486.8 mA h g-1)。即使在1000次充放电循环后仍保持高容量(99%保留初始充电容量),库仑效率为99%。绿色环保的锌- qh2电池不含重金属或过渡金属离子,不含腐蚀性或易燃性电解质,利用了丰富易得的材料。

Micropore confinement for a highly rechargeable aqueous Zn-hydroquinone battery with exceptional capacity†
A highly rechargeable battery utilizing a zinc anode, aqueous ZnSO4 electrolyte, and hydroquinone (QH2) cathode is reported. QH2 immobilized within the pores of microporous carbon delivered a high specific capacity (482 mA h g−1 at 0.5C), approaching the theoretical specific capacity of QH2 (486.8 mA h g−1). A high capacity was maintained even after 1000 charge–discharge cycles (99% retention of initial charge capacity), with 99% coulombic efficiency. The environentally green Zn–QH2 battery did not include any heavy or transition metal ions, or corrosive or flammable electrolytes, and utilized abundant and readily available materials.
