“…The VGCF film controlled and contained the formation of nanocrystal Li 2 S optimizing the contact area between Li 2 S·P 2 S 5 solid electrolyte and conductive carbon inside the electrode. The composite electrode employs both 1D VGCF and 0D carbon powder to realize a conductive framework to achieve both simple electron conduction and effective contact with Li 2 S active material .

Due to their high ionic conductivity and adeciduate mechanical features for lamination, sulfide composites have received increasing attention as solid electrolyte in all-solid-state batteries. Their smaller electronegativity and binding energy to Li ions and bigger atomic radius provide high ionic conductivity and make them attractive for practical applications. In recent years, noticeable efforts have been made to develop high-performance sulfide solid-state electrolytes. However, sulfide solid-state electrolytes still face numerous challenges including: 1) the need for a higher stability voltage window, 2) a better electrode-electrolyte interface and air stability, and 3) a cost-effective approach for large-scale manufacturing. Herein, a comprehensive update on the properties (structural and chemical), synthesis of sulfide solid-state electrolytes, and the development of sulfide-based all-solid-state batteries is provided, including electrochemical and chemical stability, interface stabilization, and their applications in high performance and safe energy storage.

“…Inspired by the cathode design in aprotic Li–S batteries, different hierarchical carbon materials, such as mesoporous carbon, reduced graphene oxide, carbon nanotube and carbon nanofibers, etc., were used in ASS batteries as well to construct the electronic pathways . Kanno and co‐workers reported using mesoporous carbon as matrix for ASS Li–S batteries to enhance the electron transport and studied the pore size effects (from 8 to 100 nm) on electrochemical performance of ASS Li–S batteries .…”

Lithium-sulfur (Li-S) batteries are one of the most promising next-generation battery types for their high energy density and low cost. On the other hand, safety issues and poor cyclability strongly limit practical application. Solidstate electrolytes (SSEs) can present as high ionic conductivity as aprotic electrolytes and eventually avoid the shuttle effect, which provides an ultimate solution for safe Li-S batteries with good cyclability. In this review, the recent achievements in all-solid-state Li-S batteries based on inorganic SSEs are summarized. Furthermore, the main attentions are paid to the interfaces, including metallic lithium|SSEs, SSEs|SSEs, and composite sulfur cathode|SSEs. The potential approaches to deal with these interfacial issues are proposed as well, such as composite SSEs with an asymmetric structure to enhance their compatibility with lithium anodes and sulfur cathodes, adding Li 2 O or LiF and increasing the densification to reduce the grain boundary resistance, and nanomaterials used to improve the kinetic process in cathode.

“…[119] Theu tilization of Li 2 Sa saraw material is an alternative approach that has recently been widely studied because of the possibility to operate with metallic lithium-free anodes.

Lithium metal (Li ) rechargeable batteries (LMBs), such as systems with a Li anode and intercalation and/or conversion type cathode, lithium-sulfur (Li-S), and lithium-oxygen (O )/air (Li-O /air) batteries, are becoming increasingly important for electrifying the modern transportation system, with the aim of sustainable mobility. Although some rechargeable LMBs (e.g. Li /LiFePO batteries from Bolloré Bluecar, Li-S batteries from OXIS Energy and Sion Power) are already commercially viable in niche applications, their large-scale deployment is hampered by a number of formidable challenges, including growth of lithium dendrites, electrolyte instability towards high voltage intercalation-type cathodes, the poor electronic and ionic conductivities of sulfur (S ) and O , as well as their corresponding reduction products (e.g. Li S and Li O), dissolution, and shuttling of polysulfide (PS) intermediates. This leads to a short lifecycle, low coulombic/energy efficiency, poor safety, and a high self-discharge rate. The use of electrolyte additives is considered one of the most economical and effective approaches for circumventing these problems. This Review gives an overview of the various functional additives that are being applied and aims to stimulate new avenues for the practical realization of these appealing devices.
