A hollow core–shell hetero-structured electrode (PANI/ZnO@ZIF-8-CC) is designed and synthesized via a ‘root-etch-wrap’ process for flexible supercapacitors. The unique structure, in situ growth strategy and synergistic effects endow PANI/ZnO@ZIF-8-CC with ultrahigh areal capacitance and good cycling stability.
A novel organic solvent-assisted freeze-drying pathway, which can effectively protect and uniformly distribute active particles, is developed to fabricate a free-standing Li2MnO3·LiNi1/3Co1/3Mn1/3O2 (LR)/rGO electrode on a large scale.
Benzoquinone with high theoretical capacity is anchored on N-plasma engraved porous carbon as a desirable cathode for rechargeable aqueous Zn-ion batteries. Such batteries display tremendous potential in large-scale energy storage applications.
Zinc-ion batteries (ZIBs) have attracted significant attention owing to their high safety, high energy density, and low cost. ZIBs have been studied as a potential energy device for portable and...
