“…ii) The negative electrodes cover carbon‐based materials (graphite and porous carbon), silicon, lithium, and Ti compounds (TiO 2 and Li 4 Ti 5 O 12 ). iii) Solid‐state electrolytes involve ion‐conductive LiNbO 3 –SiO 2 , Li 2 S–P 2 S 5 , lithium lanthanum titanium oxides (Li 3 x La (2/3)− x TiO 3 ), glassy amorphous lithium phosphates (Li 2 O–P 2 O 5 –SiO 2 ), lithium phosphorus oxynitride (LiPON), Li 14 Zn(GeO 4 ) 4 , and polymers as both electrolyte and separator. Most reported inorganic solid‐state electrolytes have low ionic conductivity of about 10 −5 S cm −1 , while polymer‐based electrolytes usually achieve higher ionic conductivity at the level of 10 −3 S cm −1 at room temperature, which are hardly comparable with the commercial organic liquid electrolyte (10 −2 S cm −1 ).…”

The rapid development and further modularization of miniaturized and self‐powered electronic systems have substantially stimulated the urgent demand for microscale electrochemical energy storage devices, e.g., microbatteries (MBs) and micro‐supercapacitors (MSCs). Recently, planar MBs and MSCs, composed of isolated thin‐film microelectrodes with extremely short ionic diffusion path and free of separator on a single substrate, have become particularly attractive because they can be directly integrated with microelectronic devices on the same side of one single substrate to act as a standalone microsized power source or complement miniaturized energy‐harvesting units. The development of and recent advances in planar MBs and MSCs from the fundamentals and design principle to the fabrication methods of 2D and 3D planar microdevices in both in‐plane and stacked geometries are highlighted. Additonally, a comprehensive analysis of the primary aspects that eventually affect the performance metrics of microscale energy storage devices, such as electrode materials, electrolyte, device architecture, and microfabrication techniques are presented. The technical challenges and prospective solutions for high‐energy‐density planar MBs and MSCs with multifunctionalities are proposed.

“…Thermal stability is typically quantified by measuring the ionogel decomposition temperature using thermogravimetric analysis (TGA). Multiple NIEs have exhibited decomposition temperatures over 300 °C, particularly when employing inorganic matrix materials such as SiO 2 , [26] TiO 2 , [21] BaTiO 3 , [27] and hexagonal BN. [12] Since these inorganic matrix materials are relatively refractory, the onset decomposition temperatures of NIEs are commonly limited by the ILs, but residual solvents and trapped Reproduced with permission.…”

“…Another challenge for solid-state electrolytes is achieving infiltration into thick porous electrodes with high areal capacities. In this regard, NIEs hold a potential advantage over competing solid-state electrolytes since they are compatible with diverse solution-processing methods (e.g., drop-casting, [20] spin-coating, [26] and inkjet printing [51] ). Solution-processing also provides opportunities for precise NIE thickness control, which allows the reduction of occupied mass/volume and resistance of the electrolyte.…”

Ionogels composed of ionic liquids and gelling solid matrices offer several advantages as solid‐state electrolytes for rechargeable batteries, including safety under diverse operating conditions, favorable electrochemical and thermal properties, and wide processing compatibility. Among gelling solid matrices, nanoscale materials have shown particular promise due to their ability to concurrently enhance ionogel mechanical properties, thermal stability, ionic conductivity, and electrochemical stability. These beneficial attributes suggest that ionogel electrolytes are not only of interest for incumbent lithium‐ion batteries but also for next‐generation rechargeable battery technologies. Herein, recent advances in nanocomposite ionogel electrolytes are discussed to highlight their advantages as solid‐state electrolytes for rechargeable batteries. By exploring a range of different nanoscale gelling solid matrices, relationships between nanoscale material structure and ionogel properties are developed. Furthermore, key research challenges are delineated to help guide and accelerate the incorporation of nanocomposite ionogel electrolytes in high‐performance solid‐state rechargeable batteries.

Ionogels have emerged as one of the most interesting and captivating form of composites which credits to the outstanding characteristics. One of the most important constituent of ionogels is ionic liquid, which show many attractive properties notably non-volatility, in-flammability, negligible vapor pressure, tunability, thermal stability and solvating ability. A large variety of matrix materials have been under consideration for ionogels, presently, polymer/ionic liquid based ionogels have attracted much attention. Numerous polymeric materials such as have been utilized for these polymer/ionic liquids based ionogels. Polyvinylidene fluoride (PVDF) has been on top of the line as a matrix material for polymer based ionogels owing to its stability, aging and chemical resistance and mechanical strength. This review is primarily concerned with the properties of polyvinylidene fluoride based ionogels with an emphasis on their applications in various domains electrochemical devices, gas separation and liquid/liquid separations.
