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: In this study, homogeneous Li2ZrO3 (LZO) was successfully coated on the surface of Li1.2Mn0.54Ni0.13Co0.13O2 (LRO) by molten salt-assisted sintering technology. The as-prepared LRO@LZO composites have improved cycling performance due to the good chemical and electrochemical stability of LZO. Additionally, Li2ZrO3 acts as an excellent lithium-ion conductor, leading to increased lithium-ion transfer rate and improved rate capacity of LRO. Therefore, this study provides a new solution to enhance the structure stability and electrochemical performance of lithium-rich manganese-based cathode materials.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries.

As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
