“…[ 122 ] With a high melting point, thermal runaways and electro‐chemical reactivity are significantly reduced (due to lack of any vaporizable organic electrolyte, that is, fuel), making liquid‐free solid‐state systems very attractive for high temperature operation. [ 123 ] SSEs (such as the garnet class) have high resistance against decomposition when under direct contact with Li metal. [ 122 ] The use of liquid‐free SSE is likely one of the best options for high temperature batteries.…”

Lithium anode-based batteries (LBs) are highly demanded in society owing to the high theoretical capacity and low reduction potential of metallic lithium. They are expected to see increasing deployment in performance critical areas including electric vehicles, grid storage, space, and sea vehicle operations. Unfortunately, competitive performance cannot be achieved when LBs operating under extreme temperature conditions where the lithium-ion chemistry fail to perform optimally. In this review, a brief overview of the challenges in developing LBs for low temperature (<0°C) and high temperature (>60°C) operation are provided followed by electrolyte design strategies involving Li salt modification, solvation structure optimization, additive introduction, and solid-state electrolyte utilization for LBs are introduced. Specifically, the prospects of using lithium metal batteries (LMBs), lithium sulfur (Li-S) batteries, and lithium oxygen (Li-O 2 ) batteries for performance under low and high temperature applications are evaluated. These three chemistries are presented as prototypical examples of how the conventional low temperature charge transfer resistances and high temperature side reactions can be overcome. This review also points out the research direction of extreme temperature electrolyte design toward practical applications.

“…Substituting liquid electrolytes with solid state electrolytes (SSEs) is the ultimate target, due to the advantage of high safety. [8][9][10][11] SSEs are generally divided into inorganic ceramic electrolyte and polymer electrolyte. [11] Longchain LiPSs are insoluble in solid phase, so that the shuttle effect would be greatly inhibited by inorganic ceramic electrolytes.…”

Despite the high specific capacity of LiÀ S battery, shuttle effect of lithium polysulfides (LiPSs) and safety issue pose a great challenge to realize its commercial application. Replacing liquid electrolyte with poly (ethylene oxide) (PEO) -based solid-state electrolyte is considered as a promising method to boost the safety, but the shuttle effect of LiPSs cannot be completely eliminated. In this work, a new kind of double-layer PEO-based polymer electrolyte is designed to restrict the LiPSs. The layer next to cathode consists of PEO and poly(vinylpyrrolidone) (PVP). The other layer consists of PEO. PVP with abundant of amide groups has been proved to have strong affinity to LiPSs. The strong interaction between LiPSs and carbonyl groups in amide is verified by Attenuated Total Reflection-Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy tests. As a result, the assembled LiÀ S battery exhibits a specific capacity of 1100 mAh g À 1 and capacity retention of 347 mAh g À 1 after 200 cycles at 60 °C and 0.05 C, while the capacity retention of the battery without PVP-blended PEO electrolyte remains only 27 % at the same conditions.

All-solid-state lithium batteries (ASSLBs) with nonflammable solid electrolytes (SEs) deliver greatly enhanced safety characteristics. Furthermore, ASSLBs composed of cathodes with high working voltages, such as LiCoO 2 , LiNi x Co y Mn z O 2 (x + y + z = 1, NCM), LiNi x Co y Al z O 2 (x + y + z = 1, NCA), LiMn x Fe y PO 4 (x + y = 1, LMFP), and LiNi 0.5 Mn 1.5 O 4 (LNMO), and a lithium metal anode can achieve comparable or better performance compared with that of LLBs in terms of energy density. Therefore, high-voltage ASSLBs have been regarded as the most promising next-generation batteries. Although significant progress has been achieved in high-voltage ASSLBs research, their development still faces multiple challenges. To facilitate further effective and target-oriented research on highvoltage ASSLBs, a summary of recent research progress is urgently needed. In this review, recent research progress in high-voltage ASSLBs is summarized from the perspectives of SEs modification, interfacial challenges and their corresponding solutions for cathodes, and high-voltage composite cathode design for practical applications. Finally, the authors' perspectives on the state of current ASSLBs research, aiming to propose possible research directions for the future development of high-voltage ASSLBs.
