ABSTRACT The current study explores the synthesis and electrochemical performance of potassium birnessite as a cathode material for sodium‐ion batteries (SIBs), achieved through partial ion exchange resulting from deintercalation followed by sodium intercalation during first cycle. Three samples (KB400, KB500, KB600) are synthesized using sol–gel method subsequently calcined at different temperatures to evaluate influence crystal water K + ions on structural stability their performance. X‐ray diffraction analysis confirms formation with high crystallinity. Additionally, fluorescence, photoelectron spectroscopy, thermogravimetric employed verify chemical composition oxidation states. Among samples, KB500 exhibits most favorable performance, achieving specific capacity 175 mAh g –1 C/10 when cycled within voltage range 1.6–4.2 V. Long‐term cycling tests narrower potential 2–3.6 V demonstrate promising values 110 in retention 90% over 80 cycles. presence interlayer is crucial enhancing diffusion. These findings suggest that could serve SIBs, providing structurally stable option energy storage applications.
