“…The capacity retention of LiNi 0.6 Co 0.2 Mn 0.2 O 2 cells could reach 80% after 175 cycles at 60 °C. Zhu et al [63] designed a kind of ionic liquid gel electrolyte that combines the anions TFSI − and FSI − and the cations (1-methyl-3-ethylimidazole (EMI + ) and 1-butyl-1-methylpyrrolidinium (PYR + 14 ) to facilitate ion transport. Due to the non-flammable properties of the ionic liquids, the electrolyte maintains high interfacial stability against LMA at 80 °C.…”

Lithium metal batteries (LMBs) are the most promising high energy density energy storage technologies for electric vehicles, military, and aerospace applications. LMBs require further improvement to operate efficiently when chronically or routinely exposed to high temperatures. Electrolyte engineering with high temperature tolerance and electrode compatibility has been essential to the development of LMBs. In this review, the primary obstacles to achieving high‐temperature LMBs are first explored. Subsequently, electrolyte tailoring options, such as lithium salt optimization, solvation structure modification, and the addition of additives are reviewed in detail. In addition, the feasibility of utilizing LMBs at high temperatures has been investigated. In conclusion, this study provides insights and perspectives for future research on electrolyte design at high temperatures.
