The combined advantages of good mechanical deformability, high Li + conductivity, and strong compatibility with 4 V-class cathodes make halide solid-state electrolytes promising candidates for high-energy all-solid-state lithium−metal batteries (ASSLMBs). Among these, the cost-effective Li 2 ZrCl 6 has garnered significant attention due to the non-inclusion of rare-earth metals. However, the conventional one-step ball-milling synthesized Li 2 ZrCl 6 always exhibits an ionic conductivity lower than 5 × 10 −4 S cm −1 in most literature. Here, a simple optimized two-step ball-milling strategy is adopted to achieve a high Li + conductivity of nearly 1 × 10 −3 S cm −1 at 30 °C for Li 2 ZrCl 6 . Simultaneously, the effects of rotational speed and ball-to-powder mass ratio on the structure and ionic conductivity of Li 2 ZrCl 6 are investigated. The Li + migration pathways in electrolytes are also studied by bond valence site energy (BVSE) calculations. Moreover, the application potential of the modified Li 2 ZrCl 6 electrolyte in ASSLMBs assembled with the LiCoO 2 cathode and the lithium−indium alloy anode has been studied. The ASSLMBs exhibit an initial discharge capacity of 123.4 mA h g −1 at room temperature (0.1 C) and a capacity retention of 71% after 50 cycles. Therefore, this study introduces an effective strategy for synthesizing high-performance halide electrolytes, thus facilitating the practical implementation of halide-based ASSLMBs.

“…The demand for renewable and clean energy sources is ever-growing due to the severe global environmental problems caused by the overconsumption of fossil fuels. − Lithium-ion batteries (LIBs) have achieved great success in portable electronic devices and electric vehicles. However, their applications in large-scale energy storage are still challenged by the shortage of lithium resources, high cost, harsh preparation conditions, and safety hazards. − Therefore, it remains urgent to develop advanced secondary battery systems with rich abundance, low cost, and high safety as a beneficial complement to LIBs.…”

Prussian white (PW) is considered one of the most promising cathode materials for sodium-ion batteries because of its large ion diffusion channels, low lattice strain, facile preparation, nontoxicity, and low cost. At present, research on PW mainly focuses on optimizing the material's structures for the ambient environment yet less on its practical application under extreme temperatures. In this Spotlight, we intend to offer progress we have made in developing PW cathode materials working over wide temperatures in terms of intrinsic feasibility and development prospects. These findings provide a direction to promote the practical viability of PW under extreme conditions.

All solid–state battery (ASSB) is widely recognized as one of the most promising high‐energy‐density systems/technologies. However, thermal safety issues induced by highly reactive materials still exist for solid electrolytes (SEs). Insights on thermal behaviors at elevated temperatures and the underlying mechanism for thermal stability of SE‐based systems are still missing. Herein, thermal stability performance of typical sulfide SEs is systematically investigated with metal Li, whose order of interfacial thermal stability is concluded to be Li6PS5Cl > Li3PS4 > Li9.54Si1.74P1.44S11.7Cl0.3 > Li4SnS4 > Li7P3S11 after a comprehensive evaluation. Interestingly, Li4SnS4, which achieves good air stability, has poor thermal stability with Li metal. This is possibly caused by Li─Sn alloy products generated during thermal decomposition, and their great thermodynamic driving force towards SE for accelerated thermal runaway. Moreover, electrolytes with poor material‐level thermal stability (e.g., Li7P3S11) may form a dense passivation layer by self‐decomposition with Li metal to retard thermal runaway. Conclusively, the material structure affects the thermodynamic stability of the system, but the reaction products (interphase) affects the kinetic process of the thermal reaction within a certain temperature range. Therefore, thermal stability with both metallic lithium and decomposition products is a necessary condition for interfacial thermal stability of sulfide SEs.
