A new design strategy for polyimides/carbon nanotube networks is reported, aiming to passivate the hydrogen-evolution mechanism on the molecular structures of electrodes, thus substantially boosting their aqueous energy-storage capabilities. The intrinsic sluggish hydrogen-evolution activity of polyimides is further passivated via Li(+) association during battery charging, leading to a much wider voltage window and exceptional energy-storage capability.
本文报道了一种用于聚酰亚胺/碳纳米管网络的新型设计策略，旨在使电极分子结构上的析氢机制钝化，从而显著提高其水系储能能力。通过在电池充电过程中与 Li(+)结合，进一步使聚酰亚胺的本征缓慢析氢活性钝化，从而获得更宽的电压窗口和卓越的储能能力。
