A high-spin Mn-tailored sodium hexacyanoferrate electronic structure enables efficient Mg<sup>2+</sup> storage
Sodium hexacyanoferrate (NaFeHCF) is a promising cathode material for aqueous magnesium-ion batteries (AMBs) but suffers from limited active site utilization. Here, high-spin Mn is incorporated into the Fe sites of NaFeHCF to modulate its electronic structure, affording NaFe<sub>0.8</sub>Mn<sub>0.2</sub>HCF. The high-spin Mn efficiently optimizes the electronic structure of NaFeHCF and enhances its storage capacity for Mg<sup>2+</sup>. This work provides insights into the rational design of high-performance electrode materials for AMBs.
