“…The ionogel showed good conductivity, but the hydrogel has no conductivity. Tang et al [6] synthesized an ionogel by using [BMIM][BF 4 ] IL, which showed good self-healing capability at −30 °C, which can self-heal within 10 h without external stimuli (Figure 4D). These results prove that IL can endow the ionogels with good antifreezing capability.…”

“…Although the structure of ionogels is similar to that of hydrogels, the difference between them is that the presence of ILs indeed makes the ionogels possess some additional properties including higher ion‐conductivity, [ 3 ] enhanced antibacterial ability, [ 4 ] improved thermal stability, [ 5 ] and better antifreezing capability. [ 6 ] Generally, ILs can function as a polymeric component of scaffold in ionogels by chemical bond connection. For instance, poly(ionic liquids) (PILs), one kind of ILs, can regulate the structure of the ionogel scaffold‐like layer and pore construction by providing controllable hydrogen bond, electrostatic, host–guest interactions and so on, [ 7 ] or they work as a dispersing medium in ionogels and be confined in the ionogel scaffold.…”

Over the past two decades, the unique features of ionic liquids (ILs) drive their exploration and exploitation in gel field and endow the gels with many excellent properties including thermal stability, antifreezing capability, mechanical strength, self-healing, conductivity, and antibacterial performance. As promising functional materials, ionogels have attracted remarkable interest in various applications including flexible electronics, energy storage, and biomedical applications. This review aims to give a detailed overview of the recent advances in developing of IL-based task-specific ionogels. The effects of ILs on the ionogels' formation and structure modification and their promotion on elevating these gel properties from the viewpoint of fundamental to the application are comprehensively discussed. The different interactions also discussed between ILs and other components in forming ionogels, such as hydrogen bond, electrostatic interaction, host-guest interaction, IL-philic and IL-phobic interaction, and introduced ILs' dissolvability to biomass; and the unique capability of ionogels owing to ILs, such as conductivity, electrochemical stability, thermal stability, and antibacterial ability. Finally, the future challenges and perspectives of ionogels are outlooked.

“…They are also known as iongels, ionic liquid gels or ionogels if an IL-based electrolyte is used. [14] Although this approach is quite popular in Li-ion, [15][16][17] Li-metal, [18][19][20] sodiummetal [21,22] or other type of batteries, [8,23] it has not been largely explored for LiÀ O 2 cells. There are a few examples based on poly(methyl) methacrylate (PMMA) [24,25] or poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) [26,27] polymerbased iongels.…”

Lithium-air/O 2 batteries are a promising battery technology for automotive applications due to their high energy density. However, many challenges need to be solved, particularly the high reactivity of the electrolyte with oxygen superoxide radicals and its low cyclability. In this work, we present a simple and fast way to prepare polymer-based iongel soft solid electrolytes. Thermally and mechanically stable iongels are prepared by fast UV-photopolymerisation exhibiting a high ionic conductivity (~1.2 × 10 À 3 S cm À 1 at 25 °C). When used as solid electrolytes in lithium symmetrical cells, they can withstand a critical current density of 0.5 mA cm À 2 . Performance in LiÀ O 2 cells showed capacities as large as 3.3 mAh cm À 2 , and cycling capability of 25 cycles, exceeding results on liquidcounterpart cells.

Lithium batteries (LBs) are developed tremendously owing to their excellent energy density as well as cyclic persistence, exhibiting promising applications from portable devices to e‐transportation and grid fields. However, with the ever‐increasing demand for intelligent wearable electronics, more requests are focused on high safety, good durability, and satisfied reliability of LBs. The self‐healing route, which can simulate the ability of organic organisms to repair damage and recover initial function through its intrinsic vitality, is believed to be an efficient strategy to alleviate the unavoidable physical or chemical fatigue and damage issues of LBs, beneficial for the realization of the above mentioned high requests. In this review, the applicability and development of self‐healing materials are summarized in electrodes, electrolytes, and interfacial layers in recent years, focusing on exploring the feasibility of different self‐healing strategies in LBs, discussing the advantages and disadvantages of existing strategies in different parts of batteries, and indicating the possible research directions for beginners who are interested in this field. Finally, the critical challenges and the future research directions as well as opportunities are prospected.
