“…It can be seen that G 0 is independent of frequency over the entire investigated frequency range for all samples, indicating a typical rubberlike behavior [57]. The similar rheological behavior has been observed for other gels that containing chemical bonds and physical networks [24,47,55]. In addition, the storage modulus increases as the gelatin content and crosslinking agent content increase, and the value can reach 6 kPa, indicating the appropriate mechanical strengths of these ionogels for applications in flexible electronics.…”

“…Gel polymer electrolytes (GPEs) are preferred to the design of stretchable and self-healable energy storage devices, due to their higher safety, flexibility, and adaptability than traditional liquid electrolytes and solid electrolytes [21][22][23][24]. Commonly, in order to dissolve the polymer hosts and electrolytic salts, the traditional organic solvents (ethylene carbonate (EC), propylene carbonate (PC), diethyl carbonate (DEC), etc.)…”

A novel chemical cross-linked ionogels with excellent self-healability, stretchability, and reprocessability based on gelatin have been synthesized via the Schiff base reaction in ionic liquid of 1-ethyl-3-methylimidazolium acetate (EMIMAc). Rheological measurements revealed that the plateaus modulus in storage modulus increases with increase in the content of gelatin. These ionogels displayed good thermal mechanical stability, and the chemical networks were not destroyed even at temperature up to 140°C. High stretchability was obtained and the elongation at break for the as-prepared ionogel could even reach 368.6%. Importantly, the prepared ionogels showed excellent self-healability and reprocessability. Remarkably, the ionogels exhibited superior ionic conductivity and room temperature ionic conductivity was higher than 1.0 9 10-3 S/cm. Furthermore, supercapacitors with this ionogel electrolyte showed temperaturedependent specific capacitance and remarkable flexible performance. Therefore, the as-prepared self-healable and reprocessable ionogels from the nature of gelatin, with highly ionic conductivity and stretchability, could be considered an excellent electrolyte candidate for various next-generation stretchable electronics.

Among various energy storage and conversion materials, functionalized natural clays display significant potentials as electrodes, electrolytes, separators, and nanofillers in energy storage and conversion devices. Natural clays have porous structures, tunable specific surface areas, remarkable thermal and mechanical stabilities, abundant reserves, and cost‐effectiveness. In addition, natural clays deliver the advantages of high ionic conductivity and hydrophilicity, which are beneficial properties for solid‐state electrolytes. This review article provides an overview toward the recent advancements in natural clay‐based energy materials. First, it comprehensively summarizes the structure, classification, and chemical modification methods of natural clays to make them suitable in energy storage and conversion devices. Then, the particular attention is focused on the application of clays in the fields of lithium‐ion batteries, lithium–sulfur batteries, zinc‐ion batteries, chloride‐ion batteries, supercapacitors, solar cells, and fuel cells. Finally, the possible future research directions are provided for natural clays as energy materials. This review aims at facilitating the rapid developments of natural clay‐based energy materials through a fruitful discussion from inorganic and materials chemistry aspects, and also promotes the broad sphere of clay‐based materials for other utilization, such as effluent treatment, heavy metal removal, and environmental remediation.

Ionogels have aroused wide interests in the field of flexible electronics. The combination of solid‐state networks and ionic liquids opens up thousands of possibilities for ionogels. The unique structures of ionogels endow them excellent mechanical properties, conductivity and thermal stability to approach the challenge of flexible electronic. A large number of new ionogels have been developed by different methods including the exchange of solution, polymeric ionic liquid and in‐situ reactions in ionic liquids (gelation of low molecular weight gelators, self‐assembly of block polymers, formation of double‐network structure, ionogel nanocomposites and direct polymerization of polymerizable monomers). The aim of this review is to discuss different preparation methods of ionogels and the comparison of their advantages.
