2024年8月1日 · In this work, iron hexacyanoferrate (FeHCF—Prussian blue) particles have been grown onto a reduced graphene oxide substrate through a pulsed electrodeposition process.

2021年12月3日 · Both the post-synthetic and in-situ vacancy repaired FeHCF products (FeHCF-P and FeHCF-I) show the significant decrease in the number of vacancy defects and the reinforced structure, which can suppress the side reactions and activate the …

2023年6月15日 · Iron hexacyanoferrate (FeHCF) is regarded as a promising cathode material of sodium-ion batteries (SIBs) due to the merits of easy preparation, low cost and three-dimensional open framework. However, the practical application of FeHCF is highly restricted by the intrinsic [Fe(CN) 6] 4-vacancy and coordinated water as well as nanoscale particles ...

2023年7月10日 · The CoHCF@FeHCF core–shell structure is designed with CoHCF as the core material and FeHCF as the shell material to enhance the electrochemical properties. The successfully prepared core–shell structure leads to a significant improvement in the rate performance and cycling stability of the composite compared to the unmodified CoHCF.
