Summary: The sluggish kinetics of sulfur reactions on the cathode and the inadequate lithium deposition/stripping reversibility on the anode are successfully mitigated by using a single cathode modifier, In2Se3, which catalyses the polysulfide reactions on the cathode and improves lithium deposition/removal reversibility on the anode through the formation of a LiInS2/LiInSe2 containing solid electrolyte interface. This single modification approach shows excellent performance in Li-metal anode-free Li-S batteries, achieving 60% capacity retention and an average Coulombic efficiency of 98.27% after 160 cycles.

Summary: Organic polyimides have drawn increasing attention in lithium-ion batteries due to their high theoretical capacities, resource sustainability, and diverse chain structures, which utilize the reversible anion stabilization mechanism of redox-active carbonyl groups. By adjusting the active anhydride units and diamine linkers, the relationship between chain structure and electrochemical performance was explored. The incorporation of flexible linkers facilitates the movement of polyimide chains, forming porous networks with abundant active sites and enhancing capacity and cycling stability; in contrast, rigid aromatic linkers lead to orderly-stacked sheets that affect capacity and rate capability.

Summary: In this study, a bifunctional electrolyte additive, 1,4-difluoroanthraquinone (DFAQ), is proposed to control lithium deposition and accelerate sulfur redox kinetics in lithium-sulfur (Li-S) batteries. DFAQ forms a solid electrolyte interphase (SEI) rich in LiF, allowing reversible lithium plating/stripping, suppressing dendrite growth, and protecting the lithium anode from side reactions with lithium polysulfides (LiPSs). Additionally, DFAQ acts as a redox mediator, promoting the conversion of LiPSs and enhancing the performance of Li-S batteries.
