Published: April 26, 2024

Abstract Prussian blue analogs (PBAs) are considered as one of the most potential electrode materials in capacitive deionization (CDI) due to their unique 3D framework structure. However, practical applications suffer from low desalination capacity and poor cyclic stability. Here, an entropy engineering strategy is proposed that incorporates high‐entropy (HE) concept into PBAs address unfavorable multistage phase transitions during CDI desalination. By introducing five or more metals, which share N coordination site, hexacyanoferrate (HE‐HCF) constructed, thereby increasing configurational system above 1.5R placing it category. As a result, developed HE‐HCF demonstrates remarkable cycling performance, with retention rate over 97% after undergoing 350 ultralong‐life cycles adsorption/desorption. Additionally, exhibits high 77.24 mg g −1 at 1.2 V. Structural characterization theoretical calculation reveal not only helps restrain transition strengthen structural stability, but also optimizes Na + ions diffusion path energy barrier, accelerates reaction kinetics thus improves performance.
