Unraveling the Role of Nitrogen‐Doped Carbon Nanowires Incorporated with MnO₂ Nanosheets as High Performance Cathode for Zinc‐Ion Batteries

Energy & environment materials, Journal Year: 2022, Volume and Issue: 6(3)

Published: March 11, 2022

Manganese‐based cathode materials are considered as a promising candidate for rechargeable aqueous zinc‐ion batteries (ZIBs). Suffering from poor conductive and limited structure tolerance, various carbon matrix, especially N‐doped carbon, were employed to incorporate with MnO 2 greatly promoted electrochemical performances. However, the related underlying mechanism is still unknown, which unfavorable guide design of high performance electrode. Herein, by incorporating layered nanowires, free‐standing hierarchical core‐shell (denoted @NC) prepared. Benefiting rational architecture, @NC electrode shows an enhanced specific capacity (325 mAh g −1 at 0.1 A ) rate (90 ), well improved cycling stability. Furthermore, improvement incorporated investigated X‐ray photoelectron spectroscopy (XPS), Raman spectrums density functional theory (DFT) calculation. The N atom elongates Mn‐O bond reduces valence Mn 4+ ion in crystal delocalizing its electron clouds. Thus, electrostatic repulsion will be weakened when Zn 2+ /H + insert into host lattices, profitable more cation insertion faster transfer kinetics higher capability. This work elucidates fundamental understanding functions composite shed light on practical pathway optimize other materials.
