“…In short, NIGs have been rather attractive for various research areas and potential technological applications in actuators, 33,34 ionic thermoelectric capacitors, 35 solid-state batteries, 36 transistors, 37 wearable sensors, [38][39][40][41][42][43] flexible supercapacitors, [44][45][46][47][48][49][50] and so forth. [51][52][53][54] This is attributed to the unique combination of several significant improved properties that NIGs offer, compared with plain IGs and conventional materials. As aforementioned, ascribing to high SSAs, nanostructured matrices in the NIGs could promote greater interactions with ILs, resulting in much-improved properties such as high ionic conductivity, outstanding thermal stability, enhanced mechanical strength, and robust electrochemical performances, as shown in Figure 2.…”

To utilize intermittent renewable energy to achieve carbon neutrality, rechargeable lithium‐based batteries have been deemed to be the most promising electrochemical systems for energy supply and storage. However, there still exist safety issues and challenges, especially originating from the intrinsic volatility and flammability of the electrolytes used in lithium‐based batteries. Due to the unique advantages of better safety, (quasi) solid‐state electrolytes have been exploited. Ionogel (IG), known as ionic liquid (IL) based monolithic quasi‐solid‐state electrolyte separator, consists of IL and gelling matrix and has become an active area of research in lithium‐based battery technology, owing to fascinating exotic characteristics including high safety (thermal stability) under extreme operating conditions, wide processing compatibility, and decent electrochemical performances. Among various gelling matrices, nanomaterials are very promising to simultaneously enhance ionic conductivity, mechanical strength, and thermal and electrochemical properties of IGs, which make the nanocomposite ionogels (NIGs). Herein, several significant advantages of NIGs as monolithic electrolyte membranes are briefly described. Also, recent advances in the NIGs for Li‐ion batteries, Li‐metal batteries, Li‐S batteries, and Li‐O2 batteries are timely and systematically overviewed. Finally, the remaining challenges and perspectives on such an interesting and active field are discussed. To the best of our knowledge, there are rare review articles focusing on the NIGs for Li‐based batteries till now. This work could offer a comprehensive understanding of recent advances and challenges of NIGs for advanced lithium storage.

In this article, molecular dynamics simulations are performed to investigate the interaction between polyvinylidene fluoride (PVDF) polymorphs (β phase has more properties compared with α, such as polarity, higher mechanical strength, and piezoelectric, ferroelectric, and pyroelectric properties), and two solvents, dimethyl sulfoxide (DMSO) and glyceryl triacetate (GTA). Pure solvent boxes are built using two force fields (Compass and Dreiding) to study the stabilization of their density and solubility, which are used with the PVDF surfaces (for each solvent, computations are performed using two surfaces α and β). According to the radial distribution function results, DMSO shows a stronger interaction with two PVDF phases, allowing it to orient chains from the α phase to the β phase, while GTA exhibits a weaker interaction due to specific hydrogen bonds. These findings are confirmed by the experiment, where the fraction F(β) reaches 62% when using DMSO, while it is 36% when using GTA.
