Abstract Lithium‐sulfur (Li‐S) batteries are considered the most promising alternative for energy storage, however, their practical applications still limited by lithium dendrites growth, slow polysulfides (LiPSs) conversion kinetics, shuttle effect, and deposition of “dead sulfur” at Li anode surface. Herein, a novel ionic liquid tetrabutylammonium triiodide (TBAI 3 ) is adopted as multi‐effect electrolyte additive to solve low coulombic efficiency short life issues Li‐S batteries. A series in situ characterization technologies, theoretical calculations, potentiostatic 2 S experiments, different kinds symmetric asymmetric cells conducted reveal multifunctional electrochemical work mechanism. It found that TBA + cations can coordinate with solvent molecules, reduce desolvation barrier, accelerate transport kinetics; they also form dynamic electrostatic shielding layer protrusions induce uniform deposition. The I − /I redox pairs continuously eliminate transforming deposits into soluble LiPSs release active substances during cycling, while reduzate be electrochemically rejuvenated when charged 2.89 V. Therefore, TBAI additives exhibit ultra‐long cycle performance 503 mAh g −1 C after 1000 cycles an average 99.99%.

Abstract Severe shuttle effect and sluggish reaction kinetics caused by lithium‐polysulfides have always been the dominant factor to reduce actual energy density of lithium–sulfur batteries. It's very important simultaneously balance surface adsorption redox conversion lithium‐polysulfides. Herein, a TiO 2 /TiN heterostructure in situ N‐doping modified multifunctional carbon interlayer is designed constructed using melamine foam as matrix material at relatively low temperature without NH 3 atmosphere. Interestingly, nano‐particles decorated on N‐enriched can be partially transformed into TiN during pyrolysis process. Based support highly conductive interconnected skeletons, N heteroatom show good synergetic soluble lithium‐polysulfides, whilst boosting electrochemical performance Consequently, when used interlayer, Super P/sulfur cathode based battery delivers high initial discharge capacity 814 mAh g −1 current rate 2.0 C maintain 548 after 500 cycles.

Abstract Lithium‐sulfur batteries (LSBs) have become one of the most powerful candidates for next‐generation battery technologies due to their high theoretical energy density and low cost. However, notorious shuttle effect soluble lithium polysulfides (LiPSs) sluggish conversion reaction kinetics cause sulfur utilization inferior cycle life. Rational catalyst design on hierarchical pore structures composition optimization is highly desired realize synergetic enrichment, accommodation, catalytic redox capacity species. In this consideration, hollow porous N‐doped carbon framework prepared, in which Co nanoparticles (NPs) are evenly embedded (denoted as Co‐HMCF) modulate electron cloud carbons. Electrochemical tests functional theory (DFT) calculations demonstrate that Co‐HMCF could simultaneously deliver superior activity accelerating LiPSs well Li 2 S nucleation/decomposition improve overall kinetics. Consequently, interlayer significantly improves performance, including discharge output (1538 mAh g −1 at 0.2 C), stable long‐term (0.047% decay per 800 cycles 1.0 exceptional rate (582 5.0 C).
