2015年12月16日 · The cuboctahedron ZnHCF (named as C-ZnHCF hereafter) particles possess the smallest mean size of ~1.7 μm and the truncated octahedron ZnHCF (named as T-ZnHCF hereafter) particles have the...

2021年11月1日 · Here we constructed a particular dual-ion battery (DIB) based on zinc hexacyanoferrate (ZnHCF) cathode, zinc metal anode, and non-aqueous K + /Zn 2+ hybrid ions electrolyte. It was revealed that K +-ions occupied almost all the cavities in ZnHCF at high voltage over 1.7 V (vs. Zn 2+ /Zn), which effectively blocked Zn 2+-ions insertion.

2022年9月16日 · The ZnHCF cathode in the Ni-containing electrolyte has the best properties such as a high specific capacity of 71.2 mA h g –1 at a current density of 100 mA g –1, 93% retention of the Coulombic efficiency, and a good rate performance manifested by a reversible capacity of 58.2 mA h g –1 at 1 A g –1. The results reveal a strategy to ...

2025年2月19日 · Herein, 3D highly-conductive host is developed to inhibit Zn dendrites growth, which have a porous structure consisting of graphene and carbon nanotubes embedded with a zincophilic nucleation sites of Zn Prussian blue analogs (ZnHCF@3D-GC).

2016年2月8日 · In the present work, we employed zinc hexacyanoferrates (ZnHCFs), which occurs as cubic or rhombic phases, as the probe to tailor the mechanism of capacity decay upon electrochemical cycling and the corresponding mitigating strategy.

2020年12月22日 · In this article, a small amount of Mn ions is successfully introduced into the N-bonded metal sites of zinc hexacyanoferrate to adjust its electrochemical stability. The N-bonded metal composition of PBAs directly affects the Zn-ion intercalation chemistry.

2022年6月1日 · Unlike a typical cubic-structured metal hexacyanoferrate, zinc hexacyanoferrates (Zn3 [Fe (CN) 6] 2 and ZnHCF) involve a Zn ion on the metal site with tetrahedral coordination to N, resulting in ZnN4 tetrahedra.

2022年8月10日 · Rechargeable aqueous Ni-ion batteries are potential candidates for future large-scale energy storage owing to their low-cost aqueous electrolytes. In this study, we report K 2 Zn 3 [Fe (CN) 6] 2 (K-ZnHCF) as a possible Ni 2+ storage material in aqueous batteries.

RZnHCF sample with cubooctahedral shape possesses the best rate capability and cyclic stability comparing with RZnHCF particles having truncated octahedral or octahedral shapes.

2025年2月19日 · Herein, 3D highly-conductive host is developed to inhibit Zn dendrites growth, which have a porous structure consisting of graphene and carbon nanotubes embedded with a zincophilic nucleation sites of Zn Prussian blue analogs (ZnHCF@3D-GC).
