Lithium‐sulfur (Li−S) batteries have attracted attention in the field of energy storage due to their high energy density and theoretical capacity. However, there are still some obstacles to achieve commercial applications such as large volume expansion of sulfur, low electrical conductivity, the growth of lithium dendrites, and the polysulfide shuttle effect. Through continuous research on Li−S batteries, renewable biomass materials have been discovered by scholars and scientists due to their sustainable development, low cost, and extensive sources. The results showed that renewable biomass‐derived carbons had outstanding advantages such as high specific surface area and large pore volume, as well as inherent heteroatom doping after being applied to Li−S batteries, which had a significant effect on improving the electrochemical performance. This Review summarizes the research progress of Li−S batteries in renewable biomass materials in recent years, starting from three aspects: biomass carbon‐sulfur composite cathodes, biomass modified separators, and biomass independent flexible carbon interlayers. Firstly, the Review summarizes its physical barrier and adsorption mechanism (the effect of various porous structures), chemical reaction and adsorption mechanism, catalysis and conversion mechanism. Then, it classifies materials based on the source of renewable biomass as well as elaborating and analyzing the structures, mechanism, and performance among them. Finally, the Review summarized the shortages in this field, as well as the challenges and opportunities faced. The authors hope that this Review will have a certain reference value for the development of various biomasses for high performance Li−S batteries, and will inspire more scholars to devote themselves to the research of biomass materials for Li−S batteries.

A functionally fluorinated emulsion and starch particles co-doped electrospun poly-m-phenyleneisophthalamide (PMIA) nanofiber membrane-based gel polymer electrolyte was produced to inhibit the “shuttle effect” of lithium polysulfides (LiPSs) and promote the transport of lithium ions for lithium-sulfur (Li-S) batteries. The high mechanical property, high thermal stability, and significant preserving liquid electrolyte of the prepared membrane are derived from the addition of functionally fluorinated emulsion and starch particles. Specially, with the chemical adsorption of –OH in starch particles and physical prevention of a gel state deriving from the prepared membrane, the lithium polysulfides are effectively controlled in the side of the cathode. In addition, the polar group and stable helix structure existing in starch particles are beneficial to the fast migration of Li+. Therefore, the battery with the Starch-F PMIA separator possesses a first-discharge capacity of 1117.8 mAh g−1 at 0.5 C. Moreover, an Li-S battery assembled with the prepared membrane also reflects preeminent rate performance, low interface impedance, and admirable cycling stability. In consequence, the Starch-F PMIA separator is a promising candidate for the progressive lithium sulfur batteries.
