Inhibiting the Jahn–Teller Effect of Manganese Hexacyanoferrate via Ni and Cu Codoping for Advanced Sodium‐Ion Batteries

et al.

Abstract: Mn‐based Prussian blue analogues (PBA) are of great interest as a prospective cathode material for sodium‐ion batteries (SIBs) due to their high redox potential, easy synthesis and low cost. However, the Jahn‐Teller effect and low electrical conductivity of Mn‐based PBA causes poor structure stability and unsatisfactory performance during the cycling. Herein, we develop a novel Ni and Cu co‐doped K2Mn[Fe(CN)6] cathode via a simple co‐precipitation strategy. The doping elements improve the electrical conductivi… Show more
