Summary: This study investigates the application of Prussian blue analogues (PBAs) as electrode materials for aqueous ammonium ion batteries (AAIBs). A PANI/Na0.73Ni[Fe(CN)(6)](0.88) hybrid (PNFF) is synthesized using a covalent bond assisted engineering with in situ polyaniline (PANI) polymerization, combining the high conductivity of PANI and the stability of PBAs. It is found that the PANI content affects the electrochemical performance of PNFF, and an optimized PANI content results in enhanced reversible capacity and cycling stability. The ammonium storage mechanism of PNFF is investigated using in situ Raman and ex situ XPS/FTIR analysis, and a durable aqueous NH4+ full cell is assembled using a polyimide@MXene anode.

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.
