Summary: Modulating the electronic orbitals through ligand engineering to enhance the catalytic activity of NiSe has been proposed in this study to accelerate the redox kinetics of LiPSs. The results show that partial substitution of Se with N strengthens the bonding strength between N-NiSe and LiPSs, facilitating the interfacial charge transfer kinetics and accelerating the redox kinetics of LiPSs. Consequently, Li-S batteries assembled with N-NiSe demonstrate high capacity and areal capacity under high-rate and high sulfur loading conditions.

Summary: Solid-state lithium-sulfur (Li-S) batteries, known for their high energy density and safety, have been hindered by slow redox kinetics and large volume change of sulfur during charge/discharge. In this study, a polymer-in-salt solid-state electrolyte is utilized to anchor sulfur in a polyacrylonitrile (PAN) substrate, leading to faster redox kinetics and smaller volume change compared to conventional Li-S batteries. The technique also introduces opportunities for designing high-performance solid-state Li-S batteries.

Summary: By designing a flower-shaped porous carbon structure with nickel nanoparticles, the issues of large polarization, low sulfur utilization, and capacity fade in lithium-sulfur batteries have been addressed. The 3D flower-shaped carbon structure enables short ionic transport lengths, while the small pore diameters and sufficient pore volume are ideal for improving charging performance at low electrolyte to sulfur ratios. The use of Ni nanoparticles on the flower-shaped network improves reaction kinetics, leading to successful demonstration of batteries with high mass loading and good cycle retention.
