使用1 M KOH和10 × 10（-3）M Zn（Ac）（2）的电解质，分别用Zn@碳纤维和Co3O4@Ni泡沫作为负极和正极，展示了水性可再充电Zn//Co 3 O 4电池。它可以在高达1.78 V的电池电压下工作，能量密度为241 W h kg（-1），并具有优异的循环性能。电池还被组装成柔性形状，可应用于需要高能量的柔性或可穿戴设备。
An aqueous rechargeable Zn//Co3O4 battery is demonstrated with Zn@carbon fibers and Co3O4@Ni foam as the negative and positive electrodes, respectively, using an electrolyte of 1 M KOH and 10 x 10(-3) M Zn(Ac)(2). It can operate at a cell voltage as high as 1.78 V with an energy density of 241 W h kg(-1) and presents excellent cycling. The battery is also assembled into a flexible shape, which can be applied in flexible or wearable devices requiring high energy.
