Summary: Surface, interface, and microstructure studies were conducted on a modified carbon-coated lithium iron silicate composite with 15% vanadium modification to understand its enhanced electrochemical performance. The study confirmed the presence of amorphous carbon coating on the composite surface and a change in the predominant crystal phase after vanadium modification. Multi-peak fitting analysis of X-ray photoelectron spectroscopy spectra identified the simultaneous presence of multivalent iron and vanadium ions. The detailed characterization of microstructure, interface, and surface provided strong evidence for the partial substitution of divalent iron with divalent vanadium and the surface modification by vanadium, resulting in increased total carbon content and improved charge transfer kinetics.

Summary: Coating the surface of all-solid-state battery cathode active material with sulfide-based solid electrolytes is crucial for enhancing battery performance. Lithium niobate (LiNbO3) is commonly used as a coating material but exhibits low durability at high charge potentials and temperatures. In this study, new hybrid coating materials of lithium niobate (Li-Nb-O) and lithium phosphate (Li-P-O) were developed, and the influence of the P/(Nb + P) ratio on durability performance was investigated. The substitution of P resulted in improved durability and lower interfacial resistance, with the hybrid coating LiP x Nb1-x O3 (x = 0.5) performing the best. Various analytical techniques were used to analyze the coated cathode active materials and reveal the mechanism behind the improved durability.
