1 Introduction. Lithium-ion batteries (LIBs) have long been considered as an efficient energy storage system on the basis of their energy density, power density, reliability, and stability, which have occupied an irreplaceable position in the study of many fields over the past decades.

In the late twentieth century, the development of nickel-metal hydride (NiMH) and lithium-ion batteries revolutionized the field with electrolytes that allowed higher energy densities. Modern advancements focus on solid-state electrolytes, which promise to enhance safety and performance by reducing risks like leakage and flammability.
High-temperature lithium-ion batteries (HLBs) are a crucial component in logging while drilling (LWD) equipment, facilitating the date acquisition, analysis, and transmission in myriametric deep formation. Conventional batteries are unable to guarantee a reliable power supply for LWD operations in extreme high-temperature conditions encountered at depths exceeding 10,000
In advanced polymer-based solid-state lithium-ion batteries, gel polymer electrolytes have been used, which is a combination of both solid and polymeric electrolytes. The use of these electrolytes enhanced the battery performance and generated potential up to 5 V.
The benefits of aqueous electrolytes for lithium batteries are even more markedly evident for Li–air batteries (Zhou et al. 2010; Girishkumar et al. 2010 ). As illustrated in Fig. 2, the theoretical specific energy of the lithium/air battery (including the oxygen cathode) is 5.2 kWh/kg.

Current research shows that high concentration electrolyte can also be applied to high-voltage lithium battery system. As the salt concentration increases, the oxidation potential of the anion decreases, and more inorganic interfacial films are formed on the cathode interface.
