“…[27][28][29][30] It has also been reported that such monoclinic PW materials suffer from rapid capacity decay and poor reversibility caused by pronounced lattice parameter changes during the phase transitions between monoclinic Na 2 Mn[Fe(CN) 6 ], cubic NaMn[Fe(CN) 6 ] and tetragonal Mn[Fe(CN) 6 ]. [27] Previous efforts to mitigate structural changes and improve stability of PWs mainly focused on partial atom replacements, [31][32][33] removal of interstitial water/vacancies, [34,35] introducing complexing agents, [36][37][38] forming conductive networks [39,40] or designing (cation) defect structures. [27] However, to our knowledge, the high-entropy approach has not yet been applied to low-symmetry, monoclinic PW battery materials.…”

The high‐entropy approach is applied to monoclinic Prussian White (PW) Na‐ion cathodes to address the issue of unfavorable multilevel phase transitions upon electrochemical cycling, leading to poor stability and capacity decay. A series of Mn‐based samples with up to six metal species sharing the N‐coordinated positions was synthesized. The material of composition Na1.65Mn0.4Fe0.12Ni0.12Cu0.12Co0.12Cd0.12[Fe(CN)6]0.92□0.08 ⋅ 1.09H2O was found to exhibit superior cyclability over medium/low‐entropy and conventional single‐metal PWs. We also report, to our knowledge for the first time, that a high‐symmetry crystal structure may be advantageous for high‐entropy PWs during battery operation. Computational comparisons of the formation enthalpy demonstrate that the compositionally less complex materials are prone to phase transitions, which negatively affect cycling performance. Based on data from complementary characterization techniques, an intrinsic mechanism for the stability improvement of the disordered PW structure upon Na+ insertion/extraction is proposed, namely the dual effect of suppression of phase transitions and mitigation of gas evolution.
