“…In addition to the impact on the charge–discharge cycle characteristics of lithium-ion batteries, it also influences lithium deposition and lithium dissolution during the formation of the SEI film in lithium-ion batteries. For example, Serizawa et al used an electrochemical quartz crystal to monitor the electrode in situ, − as shown in Figure . In this study, the SEI formed on the Cu electrode in 50.0–50.0 mol % LiTFSA-G3 SIL was characterized and evaluated.…”

At present, the basic structure and mechanism of solid electrolyte interface (SEI) have been studied based on different models. Although many researchers have observed the characteristics and properties of SEI through various characterization methods, it is still unable to explain its dynamic mechanism of action from the very small microscopic level. Among them, most researchers change the electrochemical performance of batteries by adding additives or material coating. Traditional research methods only state the performance of batteries from the appearance but lack detailed analysis of the electrochemical reaction of batteries during the research process. Based on the analysis of some models established by SEI, this study summarized the analysis of the research angle of SEI film through various characterization methods. The present traditional SEI and artificial SEI are introduced. Finally, the methods to improve the chemical performance of lithium battery and the challenges to solve the problems are summarized and prospected.

“…Furthermore, when exfoliated, their structured aluminosilicate layers provide high gravimetric surface area that results in robust nanocomposite mechanical properties . The most common clays utilized are montmorillonite, vermiculite, and halloysite for nanofillers or matrices in polymer, − polymer gel, − and ionogel − electrolytes. In these cases, the nanoclay provides mechanical support, increasing the electrolyte mechanical modulus and decreasing polymer crystallinity that enhances ionic conductivity. , Despite the breadth of demonstrated clay nanocomposite electrolytes, the most naturally abundant clay variety, kaolinite, has rarely been utilized. , The 1:1 structure of silica and alumina layers within bulk kaolinite results in strong hydrogen bonding between the layers making exfoliation difficult relative to other clay varieties. , Although kaolinite nanocomposites produced through chemical intercalation have been demonstrated, this process is time-intensive and limited to a small subset of molecules, restricting potential applications. , Only one reported system to date has shown direct liquid-phase exfoliation of kaolinite, albeit with the assistance of a large fraction of graphene oxide (GO) dispersing agent (i.e., 5:1 GO/kaolinite) and no reported yield for the process. , Therefore, a need remains for a highly scalable kaolinite exfoliation process that will enable broader use of kaolinite in SSEs and related clay nanocomposite applications.…”

Lithium-ion batteries are the leading energy storage technology for portable electronics and vehicle electrification. However, demands for enhanced energy density, safety, and scalability necessitate solid-state alternatives to traditional liquid electrolytes. Moreover, the rapidly increasing utilization of lithium-ion batteries further requires that next-generation electrolytes are derived from earth-abundant raw materials in order to minimize supply chain and environmental concerns. Toward these ends, clay-based nanocomposite electrolytes hold significant promise since they utilize earth-abundant materials that possess superlative mechanical, thermal, and electrochemical stability, which suggests their compatibility with energy-dense lithium metal anodes. Despite these advantages, nanocomposite electrolytes rarely employ kaolinite, the most abundant variety of clay, due to strong interlayer interactions that have historically precluded efficient exfoliation of kaolinite. Overcoming this limitation, here we demonstrate a scalable liquid-phase exfoliation process that produces kaolinite nanoplatelets (KNPs) with high gravimetric surface area, thus enabling the formation of mechanically robust nanocomposites. In particular, KNPs are combined with a succinonitrile (SN) liquid electrolyte to form a nanocomposite gel electrolyte with high room-temperature ionic conductivity (1 mS cm −1 ), stiff storage modulus (>10 MPa), wide electrochemical stability window (4.5 V vs Li/Li + ), and excellent thermal stability (>100 °C). The resulting KNP-SN nanocomposite gel electrolyte is shown to be suitable for high-rate rechargeable lithium metal batteries that employ high-voltage LiNi 0.8 Co 0.15 Al 0.05 O 2 (NCA) cathodes. While the primary focus here is on solid-state batteries, our strategy for kaolinite liquid-phase exfoliation can serve as a scalable manufacturing platform for a wide variety of other kaolinite-based nanocomposite applications.
