“…Non-flammable alternatives, such as deep eutectic solvents and ionic liquid-based electrolytes, have been explored to mitigate this hazard. However, polymer electrolytes, while non-flammable, often suffer from deformation and breakage during the charge-discharge process, leading to interface contact issues [154][155][156]. Addressing this challenge, self-healing electrolytes have emerged as a promising solution, capable of inhibiting such problems and improving electrochemical performance while reducing degradation.…”

Gel-based materials have garnered significant interest in recent years, primarily due to their remarkable structural flexibility, ease of modulation, and cost-effective synthesis methodologies. Specifically, polymer-based conductive gels, characterized by their unique conjugated structures incorporating both localized sigma and pi bonds, have emerged as materials of choice for a wide range of applications. These gels demonstrate an exceptional integration of solid and liquid phases within a three-dimensional matrix, further enhanced by the incorporation of conductive nanofillers. This unique composition endows them with a versatility that finds application across a diverse array of fields, including wearable energy devices, health monitoring systems, robotics, and devices designed for interactive human-body integration. The multifunctional nature of gel materials is evidenced by their inherent stretchability, self-healing capabilities, and conductivity (both ionic and electrical), alongside their multidimensional properties. However, the integration of these multidimensional properties into a single gel material, tailored to meet specific mechanical and chemical requirements across various applications, presents a significant challenge. This review aims to shed light on the current advancements in gel materials, with a particular focus on their application in various devices. Additionally, it critically assesses the limitations inherent in current material design strategies and proposes potential avenues for future research, particularly in the realm of conductive gels for energy applications.

“…While the first HBD used for the realization of DES-based electrolytes is acetamide [170] , its use has quickly become obsolete due to the instability of N-H bonds with lithium metal anodes. As a result, NMA is the main choice as the HBD to realize DES-based electrolytes for LMBs [171][172][173][174][175][176] .…”

“…Furthermore, Wang et al reported the use of an eutectogel based on Li[TFSI]:NMA (1:4 in mol) in a PEO matrix, which also contains metal-organic-framework (MOF) UiO66-NH 2 [175] . The reactivity of NMA with lithium metal was reduced due to the interaction between the NH 2 group of the MOF and the C=O group of NMA.…”

Lithium-ion batteries (LIBs) are the predominant power source for portable electronic devices, and in recent years, their use has extended to higher-energy and larger devices. However, to satisfy the stringent requirements of safety and energy density, further material advancements are required. Due to the inherent flammability and incompatibility of organic solvent-based liquid electrolytes with materials utilized in high energy devices, it is necessary to transition to alternative conductive mediums. The focus is shifting from molecular materials to a class of materials based on ions, including ionic liquids (ILs) and their derivatives such as zwitterionic ILs, polymerized ILs, and solvated ILs, which possess high levels of safety, stability, compatibility, and the ability to rationally design ILs for specific applications. Ion design is crucial to achieve superior control of electrode/electrolyte interphases (EEIs) both on anode and cathode surfaces to realize safer and higher-energy lithium-metal batteries (LMBs). This review summarizes the different uses of ILs in electrolytes (both liquid and solids) for LMBs, reporting the most promising results obtained during the last years and highlighting their role in the formation of suitable EEIs. Furthermore, a discussion on the use of deep-eutectic solvents is also provided, which is a class of material with similar properties to ILs and an important alternative from the viewpoint of sustainability. Lastly, future prospects for the optimization of IL-based electrolytes are summarized, ranging from the functional design of ionic structures to the realization of nanophases with specific features.

“…Numerous options of HBAs and HBDs as well as different mixture compositions provide great possibilities to search ES with desirable properties. Holding such great potential for practical application, ESs are widely expected as promising process media for various chemical processes, such as liquid–liquid extraction, gas capture, catalysis, electrodeposition, etc. − Identically, the challenge to realize a technically and economically advantageous ES-based process is the selection of a suitable ES. Therefore, CAMD methods have also been attempted to guide the rational screening and design of ESs by several researchers.…”

The unique physicochemical properties, flexible structural tunability, and giant chemical space of ionic liquids (ILs) provide them a great opportunity to match different target properties to work as advanced process media. The crux of the matter is how to efficiently and reliably tailor suitable ILs toward a specific application. In this regard, the computer-aided molecular design (CAMD) approach has been widely adapted to cover this family of high-profile chemicals, that is, to perform computer-aided IL design (CAILD). This review discusses the past developments that have contributed to the state-of-the-art of CAILD and provides a perspective about how future works could pursue the acceleration of the practical application of ILs. In a broad context of CAILD, key aspects related to the forward structure−property modeling and reverse molecular design of ILs are overviewed. For the former forward task, diverse IL molecular representations, modeling algorithms, as well as representative models on physical properties, thermodynamic properties, among others of ILs are introduced. For the latter reverse task, representative works formulating different molecular design scenarios are summarized. Beyond the substantial progress made, some future perspectives to move CAILD a step forward are finally provided.
