Ionogels are a new class of promising materials for use in all‐solid‐state energy storage devices in which they can function as an integrated separator and electrolyte. However, their performance is limited by the presence of a crosslinking polymer, which is needed to improve the mechanical properties, but compromises their ionic conductivity. Here, directional freezing is used followed by a solvent replacement method to prepare aligned nanocomposite ionogels which exhibit enhanced ionic conductivity, good mechanical strength, and thermal stability simultaneously. The aligned ionogel based supercapacitor achieves a 29% higher specific capacitance (176 F g −1 at 25 °C and 1 A g −1 ) than an equivalent nonaligned form. Notably, this thermally stable aligned ionogel has a high ionic conductivity of 22.1 mS cm −1 and achieves a high specific capacitance of 167 F g −1 at 10 A g −1 and 200 °C. Furthermore, the diffusion simulations conducted on 3D reconstructed tomography images are employed to explain the improved conductivity in the relevant direction of the aligned structure compared to the nonaligned. This work demonstrates the synthesis, analysis, and use of aligned ionogels as supercapacitor separators and electrolytes, representing a promising direction for the development of wearable electronics coupled with image based process and simulations.

“…It has already been well studied that heteroatom containing compounds (chemical structures see Fig. 1b), including P-AZO, [21] Ad-NH 2 , [18,22] DIM, [23] Fc, [24] and room temperature ionic liquids 1-propyl-3-methylimidazolium bis((trifluoromethyl) sulfonyl)imide (PMITFSI), [25,26] 1-butyl-3-methylimidazolium hexafluorophosphate (BMIPF 6 ) and 1-butyl-3-methylimidazolium tetrafluoroborate (BMIBF 4 ) [27] are able to form host-guest complexes with β-CD under suitable experimental conditions.

A facile and efficient strategy for the synthesis of heteroatom-doped carbon materials was developed, in which host-guest inclusion complexes were employed as versatile precursors. Inclusion of heteroatom containing guest molecules in the cavity of host molecules (such as cyclodextrins and cucurbit[n]urils) not only doped the carbon frameworks with heteroatoms (for instance, nitrogen, sulfur, boron, fluorine and iron), but also highly improved the carbonization yield. Since the chemical structure (composition) of host-guest inclusion complexes can be finely tuned at molecular level, they are ideal small molecular precursors for heteroatoms doped carbon materials. A nitrogen-doped porous carbon material derived from inclusion complexes exhibited a high performance as supercapacitors electrode with a high specific capacitance (348 F g-1) at a current density of 1 A g-1 in 6 M KOH aqueous solution and good cycling stability over 5000 cycles, demonstrating its potential application in energy storage.

applications, including solid electrolytes, [7] energy storage/generation devices, [8][9][10] electroactive actuators, [11] strain sensors, [12,13] soft robotics, [14] stretchable touch panels, [15] membrane separation, [16] and so on.To further expand the applications of ionogels, different strategies have been reported to combine various other desirable properties with ionogels, including self-healing capability, [17][18][19] high mechanical strength and resilience, [20,21] resistance against water and organic solvents, [22,23] and self-adhesiveness. [12,24] The integration of different properties with the highly conductive and stable nature of ionogels is essential to meet the requirements for practical applications in complex scenarios. For example, very recently, Wu et al. reported a class of ionogels with underwater self-healing ability and underwater adhesiveness, which demonstrated intriguing applications such as underwater communication. However, these ionogels showed only moderate conductivity, strain-softening behavior, and moderate mechanical recoverability. [25] Although multifunctional hydrogels have been extensively studies in recent years, [26][27][28] to date, it is still a great challenge to design ionogels that combine high comprehensive performance and multiple functions.Herein, we report the design and characterization of a class of physically crosslinked multifunctional ionogels that are highly transparent (>92% in visible region), highly stretchable (up to 2066%), mechanically strong (breaking strength up to 0.72 MPa), highly conductive (up to 2.92 mS cm −1 at 25 °C), and is capable to self-heal at room temperature both in air and under water. Besides, this kind of ionogel shows excellent resistance against aqueous solutions and some organic solvents, strong underwater adhesion to diverse substrates, and can be feasibly recycled by dissolving in ethanol and reprocessed into arbitrary shapes. Moreover, the ionogel-based sensor shows sensitive and repeatable sensing signals for a wide range deformation in tension or compression, including stable strain sensing in diverse liquid media, which was used for the reliable and sensitive wearable strain sensor to monitor human's motions. Our study would provide a kind of multifunctional ionogels with excellent comprehensive performance for wearable devices and sensing applications.Ionogels have gained increasing attentions as a flexible conductive material. However, it remains a big challenge to integrate multiple functions into one gel that can be widely applied in various complex scenes. Herein, a kind of multifunctional ionogels with a combination of desirable properties, including transparency, high stretchability, solvent and temperature resistance, recyclability, high conductivity, underwater self-healing ability, and underwater adhesiveness is reported. The ionogels are prepared via one-step photoinitiated polymerization of 2,2,2-trifluoroethyl acrylate and acrylamide in a hydrophobic ionic liquid. The abundant noncovalent interactions includi...
