All-solid-state lithium−sulfur batteries (ASSLSBs) are considered to be a promising solution for the next generation of energy storage systems due to their high theoretical energy density and improved safety. However, the practical application of ASSLSBs is hindered by several critical challenges, including the poor electrode/electrolyte interface, sluggish electrochemical kinetics of solid−solid conversion between S and Li 2 S in the cathode, and big volume changes during cycling. Herein, the 85(92Li 2 S-8P 2 S 5 )-15AB composite cathode featuring an integrated structure of a Li 2 S active material and Li 3 PS 4 solid electrolyte is developed by in situ generating a Li 3 PS 4 glassy electrolyte on Li 2 S active materials, resulting from a reaction between Li 2 S and P 2 S 5 . The wellestablished composite cathode structure with an enhanced electrode/electrolyte interfacial contact and highly efficient ion/electron transport networks enables a significant enhancement of redox kinetics and an areal Li 2 S loading for ASSLSBs. The 85(92Li 2 S-8P 2 S 5 )-15AB composite demonstrates superior electrochemical performance, exhibiting 98% high utilization of Li 2 S (1141.7 mAh g (Li2S)−1) with both a high Li 2 S active material content of 44 wt % and corresponding areal loading of 6 mg cm −2 . Moreover, the excellent electrochemical activity can be maintained even at an ultrahigh areal Li 2 S loading of 12 mg cm −2 with a high reversible capacity of 880.3 mAh g −1 , corresponding to an areal capacity of 10.6 mAh cm −2 . This study provides a simple and facile strategy to a rational design for the composite cathode structure achieving fast Li−S reaction kinetics for high-performance ASSLSBs.

“…The long-chain polysulfides at the anode are then semi-permanently reduced into insoluble Li 2 S. The consequences are (a) reduced active material, which decreases capacity; (b) decreased Li-ion diffusion due to a build-up of non-reactive LiPSs; (c) large volume expansion that may break the enclosed LSB; and (d) fast self-discharging that makes commercialization difficult. While using solid-state electrolytes can effectively prevent the shuttle effect, LSBs with even the latest solid-state electrolytes are not commercially viable due to poor ionic conductivity and slow redox kinetics that limit energy storage and power density [ 31 , 32 , 33 ]. Thus, there have been great efforts to mitigate the shuttle effect using novel NF separators in liquid electrolytes.…”

Recent Development in Novel Lithium-Sulfur Nanofiber Separators: A Review of the Latest Fabrication and Performance Optimizations

Lithium-Sulfur batteries (LSBs) are one of the most promising next-generation batteries to replace Li-ion batteries that power everything from small portable devices to large electric vehicles. LSBs boast a nearly five times higher theoretical capacity than Li-ion batteries due to sulfur’s high theoretical capacity, and LSBs use abundant sulfur instead of rare metals as their cathodes. In order to make LSBs commercially viable, an LSB’s separator must permit fast Li-ion diffusion while suppressing the migration of soluble lithium polysulfides (LiPSs). Polyolefin separators (commonly used in Li-ion batteries) fail to block LiPSs, have low thermal stability, poor mechanical strength, and weak electrolyte affinity. Novel nanofiber (NF) separators address the aforementioned shortcomings of polyolefin separators with intrinsically superior properties. Moreover, NF separators can easily be produced in large volumes, fine-tuned via facile electrospinning techniques, and modified with various additives. This review discusses the design principles and performance of LSBs with exemplary NF separators. The benefits of using various polymers and the effects of different polymer modifications are analyzed. We also discuss the conversion of polymer NFs into carbon NFs (CNFs) and their effects on rate capability and thermal stability. Finally, common and promising modifiers for NF separators, including carbon, metal oxide, and metal-organic framework (MOF), are examined. We highlight the underlying properties of the composite NF separators that enhance the capacity, cyclability, and resilience of LSBs.

“…[11][12][13] Particularly, sulfide solid electrolytes such as Li 7 P 3 S 11 , Li 10 GeP 2 S 12 , and Li 6 PS 5 Cl have attracted extensive attention due to their high ionic conductivity (>10 −3 S cm −1 ) and favorable mechanical properties. [14][15][16] In general, the conversion of sulfur in ASSLSBs does not involve the formation of soluble LiPSs, so the polysulfide shuttle effect can be fundamentally solved. [17][18][19] However, low intrinsic ionic/electronic conductivity and large volume expansion of sulfur, as well as the decomposition of sulfide electrolyte at the cathode/anode interface remain great challenges to realize high performance of ASSLSBs.…”

All‐solid‐state Li–S batteries (ASSLSBs) have exhibited great promise as next‐generation energy storage systems due to the elimination of the shuttle effect and flammability. However, the low reactivity of sulfur and poor solid–solid contact in the composite cathode result in limited electrochemical performances. Here, a Co‐N4‐decorated carbon composite is prepared by direct ball milling and serves as a sulfur host for ASSLSBs. The uniform distribution of Co‐N4 can effectively accelerate the redox conversion of sulfur and inhibit the agglomeration of sulfur particles during cycling through strong chemical affinity. Benefiting from these merits, the sulfur cathode with a sulfur content of 40% and a sulfur loading of 1.5 mg cm−2 in ASSLSBs exhibits high reversible capacity (1439 mAh g−1 at 0.1 C) and superior long‐term cyclic performance (capacity fade rate of 0.025% per cycle for 1000 cycles at 0.5 C). Even under a sulfur loading up to 4.5 mg cm−2, the areal capacity can reach 5.13 mAh cm−2 at 60 °C and maintain stable cycling over 300 cycles at 0.3 C. This work offers a promising strategy for enhancing the electrochemical performance of ASSLSBs.
