Electron Distribution Regulation of Nanoparticle Assembled Hollow Structured Fe 3 O 4 @ZnFe 2 O 4 @NC/Mo 2 TiC 2 T x for High‐Performance Aqueous Zinc‐Ion Batteries

Abstract Exploring advanced high‐performance electrode materials for aqueous zinc‐ion batteries (AZIBs) is of enormous significance for the development and commercial application of AZIBs. Herein, nanoparticle assemble hollow structured Fe 3 O 4 @ZnFe 2 O 4 @NC/Mo 2 TiC 2 T x with excellent specific capacity and cycling performance is fabricated via a designed method, and an advanced strategy is First proposed to modulate charge storage performance. The superior specific capacity can be attributed to the enhanced electrochemical activity and reversibility, which are mainly achieved by in situ Zn adulteration to trigger the electron redistribution between Fe, Zn, and O atoms. Additionally, the unique structure…
