Article Synopsis
- Lithium-sulfur (Li-S) batteries are promising due to their high capacity and low cost, but face issues like the shuttle effect of lithium polysulfide (LiPS) and weak cathode structures.
- Researchers developed a new polymer binder using poly(acrylic acid) (PAA), poly(vinyl alcohol) (PVA), and boric acid (BA) to improve Li-S battery performance by effectively reducing the shuttle effect and enhancing stability.
- The new PAA-PVA-BA copolymer binder (PPB) showed excellent cycling performance, retaining 84.4% capacity after 200 cycles and achieving high discharge capacity at increased rates, indicating a promising method for enhancing Li-S battery longevity.

Article Synopsis
- The study focuses on enhancing the mechanical properties and corrosion resistance of aluminum foams by applying a SiC/TiN nanoparticles reinforced Ni-Mo coating via electrodeposition.
- Coating morphologies were examined using SEM, and their structural characteristics were analyzed with XRD and TEM, optimizing the electrodeposition voltage to 6.0 V for best results.
- Evaluation of mechanical and corrosion resistance showed notable improvements, with a significant increase in work done and strength of the aluminum foams, as well as enhanced self-corrosion and pitting potentials after the coating was applied.
