Synergistic intercalation-conversion reaction mechanism in Prussian blue analogue materials toward enhanced Na-storage.

ABSTRACT: Sodium-ion batteries (SIBs) have emerged as promising candidates for large-scale energy storage systems owing to the abundant and low-cost sodium resources. Among various cathode materials, Prussian blue analogues (PBAs) show great promise due to their three-dimensional open framework and easy synthesis process. However, critical challenges including limited electron transfer, blocked electronic pathways between particles, excessive lattice water content, and structural instability during cycling significantly compromise their electrochemical performance. Herein, we have developed a lead hexacyanoferrate/carbon nanotube composite (PbHCF/CNTs) through rational interface design to improve the electrochemical performance. The PbHCF/CNTs electrode exhibits a four-electron transfer capacity bas
