Abstract

Abstract : 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.
