“…Reversible Mg plating/stripping is observed for various SPEs or GPEs such as PEO/Mg(BH 4 ) 2 , PMMA-MgTr, oligo(ethylene oxide)-grafted polymethacrylate-Mg-salt, P(VdFco-HFP), Mg(ClO 4 ) 2 -SiO 2 , and Mg(AlCl 2 EtBu) 2 -PVdF, however, poor ion transfer kinetics and interfacial instabilities constrains the MIBs performances. [102,298,[502][503][504][505][506][507] Mg metal undergoes massive volume expansions of 300-500% with strong stress-strain upon solid-solid phase transformations; the Mg-alloy type anode can be the alternate solution. Several Mgalloy-based anodes, such as 𝛽-Mg 3 -Bi 2 , Mg 2 -Ga 5 , Mg 2 Sn, Mg 2 -Sb, and MgF 2 -Mg, are also reported to increase the compatibility of Mg-alloys anodes.…”

Solid‐state batteries (SSBs) have received significant attention due to their high energy density, reversible cycle life, and safe operations relative to commercial Li‐ion batteries using flammable liquid electrolytes. This review presents the fundamentals, structures, thermodynamics, chemistries, and electrochemical kinetics of desirable solid electrolyte interphase (SEI) required to meet the practical requirements of reversible anodes. Theoretical and experimental insights for metal nucleation, deposition, and stripping for the reversible cycling of metal anodes are provided. Ion transport mechanisms and state‐of‐the‐art solid‐state electrolytes (SEs) are discussed for realizing high‐performance cells. The interface challenges and strategies are also concerned with the integration of SEs, anodes, and cathodes for large‐scale SSBs in terms of physical/chemical contacts, space‐charge layer, interdiffusion, lattice‐mismatch, dendritic growth, chemical reactivity of SEI, current collectors, and thermal instability. The recent innovations for anode interface chemistries developed by SEs are highlighted with monovalent (lithium (Li+), sodium (Na+), potassium (K+)) and multivalent (magnesium (Mg2+), zinc (Zn2+), aluminum (Al3+), calcium (Ca2+)) cation carriers (i.e., lithium‐metal, lithium‐sulfur, sodium‐metal, potassium‐ion, magnesium‐ion, zinc‐metal, aluminum‐ion, and calcium‐ion batteries) compared to those of liquid counterparts.

“…All-solid-state batteries with solid electrolytes (SEs) not only have the potential to address the safety issues of traditional Li-ion batteries by eliminating flammable liquid organic electrolytes but also show considerable potential for increasing energy density by incorporating metal anode. − One of the crucial aspects of these batteries is developing efficient SEs with high ionic conductivity and favorable interfacial compatibility. Several SE materials have been extensively studied including oxides, , sulfides, , polymers, , and hydridoborates. − Among these SE materials, hydridoborates exhibit several distinctive advantages, for example, higher gravimetric energy densities, better interfacial contact, and favorable compatibility with metal anodes. − These characteristics have marked hydridoborates as one of the most promising SEs for all-solid-state batteries.…”

All-solid-state potassium metal batteries have been considered promising candidates for large-scale energy storage because of abundance and wide availability of K resources, elimination of flammable liquid organic electrolytes, and incorporation of high-capacity K metal anode. However, unideal K-ion conductivities of most reported K-ion solid electrolytes have restricted the development of these batteries. Herein, a novel K 2 B 10 H 10 •CO(NH 2 ) 2 complex is reported, forming by incorporating urea into K 2 B 10 H 10 , to achieve an enhanced K-ion conductivity. The crystal structure of K 2 B 10 H 10 •CO(NH 2 ) 2 was determined as a monoclinic lattice with the space group of C2/c (No. 15). K 2 B 10 H 10 •CO(NH 2 ) 2 delivers an ionic conductivity of 2.7 × 10 −8 S cm −1 at 25 °C, and reaching 1.3 × 10 −4 S cm −1 at 80 °C, which is about 4 orders of magnitude higher than that of K 2 B 10 H 10 . One possible reason is the anion expansion in size due to the presence of dihydrogen bonds in K 2 B 10 H 10 •CO(NH 2 ) 2 , resulting in an increase in the K−H bond distance and the electrostatic potential, thereby enhancing the mobility of K + . The K-ion conductivity is also higher than those of most hydridoborate-based K-ion conductors reported. Besides, K 2 B 10 H 10 •CO(NH 2 ) 2 reveals a wide electrochemical stability window and remarkable interface compatibility with K metal electrodes, suggesting a promising electrolyte for all-solid-state K metal batteries.

Polymer electrolytes play a crucial role in advancing rechargeable magnesium batteries (RMBs) owing to their exceptional characteristics, including high flexibility, superior interface compatibility, broad electrochemical stability window, and enhanced safety features. Despite these advantages, research in this domain remains nascent, plagued by single preparation approaches and challenges associated with the compatibility between polymer electrolytes and Mg metal anode. In this study, we present a novel synthesis strategy to fabricate a glycerol α,α'‐diallyl ether‐3,6‐dioxa‐1,8‐octanedithiol‐based polymer electrolyte supported by glass fiber substrate (GDT@GF) through anion modification and thiol‐ene click chemistry polymerization. The developed route exhibits novelty and high efficiency, leading to the production of GDT@GF membranes featuring exceptional mechanical properties, heightened ionic conductivity, elevated Mg2+ transference number, and commendable compatibility with Mg anode. The assembled modified Mo6S8||GDT@GF||Mg cells exhibit outstanding performance across a wide temperature range and address critical safety concerns, showcasing the potential for applications under extreme conditions. Our innovative preparation strategy offers a promising avenue for the advancement of polymer electrolytes in high‐performance rechargeable magnesium batteries, while also opens up possibilities for future large‐scale applications and the development of flexible electronic devices.
