摘要：

Manganese-based Prussian blue analogues (Mn-PBAs) are considered top contenders for cathode materials in sodium-ion batteries (SIBs). Yet, their electrochemical performance is significantly hindered by the presence of numerous [Fe(CN) 6 ] 4− vacancies and Jahn-Teller distortion of Mn. To address this, a technique involving chaotic microflow field utilization and Ni-doping was adopted to prepare a series of MnNi-PBAs with different Mn/Ni ratios. Computational fluid dynamics (CFD) analysis confirms that the oscillating feedback microreactor (OFM...
