The synthesis of mesoporous Prussian blue analogues through a template-free methodology and the application of these mesoporous materials as high-performance cathode materials in sodium-ion batteries is presented. Crystalline mesostructures were produced through a synergistically coupled nanocrystal formation and aggregation mechanism. As cathodes for sodium-ion batteries, the Prussian blue analogues all show a reversible capacity of 65 mA h g-1 at low current rate and show excellent cycle stability. The reported method stands as an environmentally friendly and low-cost alternative to hard or soft templating for the fabrication of mesoporous materials.
本文提出了一种无模板法合成介孔普鲁士蓝类似物，并将这些介孔材料作为高性能钠离子电池阴极材料的应用。通过协同耦合的纳米晶形成和聚集机制制备了结晶介孔结构。作为钠离子电池的阴极，普鲁士蓝类似物在低电流速率下均表现出 65 mA h g-1 的可逆容量，并表现出优异的循环稳定性。与硬模板或软模板相比，所报道的方法为介孔材料的制备提供了一种环保且低成本的替代方案。
