“…Low electronic conductivity of the metal sulfide FeS 2 was not enough to provide an electronic channel for the composite cathode; to obtain a good electronic network, a conductive additive and FeS 2 were ball milled at high energy. Furthermore, it has been reported that the formation of low-curvature ion channels in the composite positive electrode by small particles of active material contributes to ion diffusion .…”

“…Researchers have carried out a lot of research in this field, but there are few electrode materials available for ASSNBs. Transition-metal sulfides (TMS), e.g., FeS 2 , TiS 2 , VS 2 , etc., mainly benefit from their stable structure and high specific capacity, which makes TMS an excellent candidate for sodium-ion cathode materials. − Furthermore, the use of nonoxide active materials (AM) not only suppresses the phenomenon of space charge layers between AM|SE but also ensures that the electrolyte does not oxidize over long cycling and that there is almost no gas emission . In particular, pyrite (FeS 2 ) is a typical transition cathode material, is the most widely distributed, and has the largest reserves of natural sulfide ore, with its main composition of FeS 2 material based on the multielectron reaction of a theoretical specific capacity of 894 mA h g –1 .…”

FeS 2 conversion electrode materials demonstrate excellent (electro)chemical stability with sulfide electrolytes and can provide a high capacity at room temperature. However, the effect of operating temperature on their conversion kinetics and capacity has not yet been reported. In this study, we incorporated ionic conductors of Na 3 PS 4 as ionic additives in the composite cathode and separator layer. The additives exhibit high ionic conductivity and good anode stability. The increased operating temperature accelerates the Na + ion diffusion rate in both Na 3 PS 4 solid electrolyte and cathode composite mixture, resulting in reduced resistance and excellent electrochemical performance for the corresponding all-solid-state sodium battery. XPS results indicate that the FeS 2 active material maintains its original activity over extended cycles at varying operating temperatures. Moreover, the Na 3 PS 4 solid electrolyte undergoes slight decomposition when induced by conductive carbon at room temperature, and this phenomenon worsens with increasing working temperatures. Na 2 Sn/Na 3 PS 4 /FeS 2 shows high discharge capacities and superior cyclability at various operating temperatures. It delivers discharge capacities of 264.4 and 585.3 mA h g −1 at 30 and 60 °C, respectively, when cycled at 0.5 A g −1 and retains a discharge capacity of 210.3 mA h g −1 after 260 cycles and 425.8 mA h g −1 after 700 cycles. These results provide guidance for designing high-energydensity, all-solid-state sodium batteries with conversion electrode materials.

“…Also, transition metal sulfides demonstrate enhanced electrochemical performance, with high reversible capacities and improved cycling stability, essential for long-lasting energy storage solutions. Despite these advantages, challenges such as volume expansion during cycling and poor electrical contact with solid electrolytes need to be addressed through further research and development [156]. Another research uses an organic solvent, N-methylformamide (NMF) to dissolution and recrystallization of Li3PS4 to prepare a solid electrolyte [157].…”

Solid-state batteries (SSBs) have emerged as a promising alternative to conventional lithium-ion batteries, with notable advantages in safety, energy density, and longevity, yet the environmental implications of their lifecycle, from manufacturing to disposal, remain a critical concern. This review paper examines the environmental impacts associated with the production, use, and end-of-life management of SSBs, starting with the extraction and processing of raw materials which highlights significant natural resource consumption, energy use, and emissions. A comparative analysis with traditional battery manufacturing underscores the environmental hazards of novel materials specific to SSBs. The review also assesses the operational environmental impact of SSBs by evaluating their energy efficiency and carbon footprint in comparison to conventional batteries, followed by an exploration of end-of-life challenges including disposal risks, regulatory frameworks, and the shortcomings of existing waste management practices. A significant focus is placed on recycling and reuse strategies, reviewing current methodologies like mechanical, pyrometallurgical, and hydrometallurgical processes, along with emerging technologies that aim to overcome recycling barriers, while also analyzing the economic and technological challenges of these processes. Additionally, real-world case studies are presented, serving as benchmarks for best practices and highlighting lessons learned in the field. In conclusion, the paper identifies research gaps and future directions for reducing the environmental footprint of SSBs, underscoring the need for interdisciplinary collaboration to advance sustainable SSB technologies and contribute to balancing technological advancements with environmental stewardship, thereby supporting the transition to a more sustainable energy future.

“…[7][8][9][10][11] To counter the issues associated with conversion-based LIBs, transition metal sulfides as "sulfur-equivalent" electrodes have been investigated. [12][13][14] Since the covalent bonds between transition metals and sulfur are stronger than the ionic interactions of lithium and sulfur, transition metal sulfide electrodes can contribute to reducing sulfur dissolution into the electrolyte. Moreover, these materials offer a high gravimetric capacity similar to sulfur-based electrodes, given that the conversion of sulfur into lithium sulfide is the plausible mechanism in LiSBs.…”

Despite large theoretical energy densities, metal‐sulfide electrodes for energy storage systems face several limitations that impact the practical realization. Here, we present the solution‐processable room temperature (RT) synthesis, local structures, and application of a sulfur‐rich Mo3S13 chalcogel as a conversion‐based electrode for lithium‐sulfide batteries (LiSBs). The structure of the amorphous Mo3S13 chalcogel is derived through operando Raman spectroscopy, synchrotron X‐ray pair distribution function (PDF), X‐ray absorption near edge structure (XANES), and extended X‐ray absorption fine structure (EXAFS) analysis, along with ab initio molecular dynamics (AIMD) simulations. A key feature of the three‐dimensional (3D) network is the connection of Mo3S13 units through S‐S bonds. Li/Mo3S13 half‐cells deliver initial capacity of 1013 mAh g‐1 during the first discharge. After the activation cycles, the capacity stabilizes and maintains 312 mAh g‐1 at a C/3 rate after 140 cycles, demonstrating sustained performance over subsequent cycling. Such high‐capacity and stability are attributed to the high density of (poly)sulfide bonds and the stable Mo‐S coordination in Mo3S13 chalcogel. These findings showcase the potential of Mo3S13 chalcogels as metal‐sulfide electrode materials for LiSBs.
