摘要

六氰高铁酸钠（NaFeHCF）是一种很有前途的水镁离子电池正极材料，但其活性位点利用率有限。在这里，高自旋Mn被掺入到NaFeHCF的Fe位点来调节其电子结构，得到NaFe0.8Mn0.2HCF。高自旋Mn有效地优化了NaFeHCF的电子结构，提高了其对Mg2+的存储能力。这项工作为AMBs高性能电极材料的合理设计提供了见解。

High-spin Mn tailoring sodium hexacyanoferrate electronic structure enables efficient Mg 2+ storage

Sodium hexacyanoferrate (NaFeHCF) is a promising cathode material for aqueous magnesium-ion batteries (AMBs) but suffers from limited active sites utilization. Here, high-spin Mn is incorporated into the Fe sites of NaFeHCF to modulate its electronic structure, affording NaFe0.8Mn0.2HCF. The high-spin Mn efficiently optimizes the electronic structure of NaFeHCF and enhances its storage capacity for Mg2+. This work provides insights into the rational design of high-performance electrode materials for AMBs.
