Summary: Here, a bidirectional polarization strategy is proposed to improve the efficiency and durability of lithium-sulfur batteries. By co-doping N and B in graphene matrix (BNrGO), the electron redistribution enables a higher polysulfide affinity, resulting in strong sulfur immobilization and fast conversion kinetics. The BNrGO cathode host matrix exhibits excellent cycling stability over 1000 cycles and high rate capability up to 10 C. This study provides valuable insights into the interaction between doping engineering and sulfur electrochemistry for superior Li-S batteries.

Summary: Lithium-sulfur (Li-S) batteries have high theoretical capacity, high theoretical capacity density, and low cost, making them a promising energy storage system. However, challenges such as poor sulfur conductivity, the shuttle effect caused by lithium polysulfide, and lithium dendrite growth hinder the commercial development of Li-S batteries. The separator, as a crucial component, plays a vital role in mitigating the shuttle effect. This review summarizes the applications of various separator preparation and modification methods in Li-S batteries and analyzes their electrochemical performance.

Summary: Researchers have designed and prepared a Mo2C/C nanoparticle-embedded carbon nanosheet matrix material for lithium-sulfur battery separator modification. The Mo2C/C material acts as a polar catalyst, effectively adsorbing and promoting the reversible conversion of lithium polysulfides, suppressing the shuttle effect, and improving the electrochemical performance of the battery. The lithium-sulfur battery with the Mo2C/C-modified separator demonstrated high specific capacities and stable cycling, indicating great promise for high-energy-density lithium-sulfur batteries.

Summary: Lithium sulfur batteries have high theoretical capacity and energy, but their practical applications are limited by the polysulfide shuttling effect. Metal-organic frameworks (MOFs) have been explored as separators to mitigate this effect. This review presents the latest research progress on MOF-based separators for LSBs, focusing on the rational design of MOFs to anchor polysulfides and facilitate Li+ transportation. The challenges and prospects for designing high-performance LSBs using MOF-based separators are also discussed.

Summary: A novel approach using a carbon-based material as an interlayer in lithium-sulfur batteries (LSBs) has been proposed to enhance their performance. By suppressing the crossover of lithium polysulfides to the anode, the reutilization of the sulfur cathode is increased. Activated carbons (ACs) were prepared using coffee waste and potassium hydroxide as an activation agent at different reaction temperatures, showing improved surface areas and pore volumes. The AC sample prepared at 800 degrees C exhibited enhanced capacity and cycling performance as a functional separator for LSB while suppressing the shuttle effect of lithium polysulfides.

Summary: Carbon particles with a hierarchical structure, derived from biomass through a pyrolysis/activation process, are used as a cathode material for room-temperature sodium-sulfur batteries. The carbon particles, loaded with sulfur, exhibit excellent cycle stability, high capacity retention, and improved utilization of sulfur due to their large specific surface area, enriched microporous structure, and nitrogen and oxygen doping.
