“…From the initial discharge data and rate performance in Figure d,e , it is evident that electron transport is a limiting factor at high discharge rates. To obtain high rate performance, it is crucial to ensure effective charge transfer pathways both at the interface and through the interstitial regions …”

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.

“…In addition, this phenomenon may be related to the low Coulombic efficiency (62.28%) of the composite electrode mixed at 1500 rpm, which is attributed to the formation of a larger solid–electrolyte interphase owing to the increase in surface area due to exfoliation of NG (Figure G) . Note that mild preparation of the composite electrode is essential .…”

Efficient cell design and fabrication of concentration‐gradient composite electrodes for high‐power and high‐energy‐density all‐solid‐state batteries

All‐solid‐state batteries are promising energy storage devices in which high‐energy‐density and superior safety can be obtained by efficient cell design and the use of nonflammable solid electrolytes, respectively. This paper presents a systematic study of experimental factors that affect the electrochemical performance of all‐solid‐state batteries. The morphological changes in composite electrodes fabricated using different mixing speeds are carefully observed, and the corresponding electrochemical performances are evaluated in symmetric cell and half‐cell configurations. We also investigate the effect of the composite electrode thickness at different charge/discharge rates for the realization of all‐solid‐state batteries with high‐energy‐density. The results of this investigation confirm a consistent relationship between the cell capacity and the ionic resistance within the composite electrodes. Finally, a concentration‐gradient composite electrode design is presented for enhanced power density in thick composite electrodes; it provides a promising route to improving the cell performance simply by composite electrode design.

“…Mechanical milling is one of the most common ways to mix components and reduce material particle size, which can be conducted in single or multiple steps depending on the adding order of components. Noh et al [191] investigated five different mixing protocols of an LCO/96(78Li 2 SÁ22P 2 S 5 )Á4Li 2 SO 4 /Super P composite cathode (Fig. 11a).…”
