A structure optimized Prussian blue analogue Na1.76Ni0.12Mn0.88[Fe(CN)6]0.98 (PBMN) is synthesized and investigated. Coexistence of inactive Ni(2+) (Fe-C≡N-Ni group) with active Mn(2+/3+) (Fe-C≡N-Mn group) balances the structural disturbances caused by the redox reactions. This cathode material exhibits particularly excellent cycle life with high capacity (118.2 mA h g(-1)).
合成并研究了一种结构优化的普鲁士蓝类似物Na1.76Ni0.12Mn0.88[Fe(CN)6]0.98（PBMN）。惰性Ni(2+)（Fe-C≡N-Ni基团）与活性Mn(2+/3+)（Fe-C≡N-Mn基团）共存平衡了氧化还原反应引起的结构扰动。这种正极材料表现出特别优异的循环寿命和高容量（118.2 mA h g(-1)）。
