“…All the adsorption/desorption isotherms (Fig. 5a) exhibit the type I feature with a rapid and analogous increase at P/P 0 < 0.05, coupled with obvious hysteresis loops (P/P 0 ¼ 0.45-0.95), demonstrating the coexistence of abundant micropores and considerable mesopores in BSAC-A-n. 37 In addition, a slight upward tendency at high relative pressure (P/P 0 ¼ 0.95-1.0) indicates the existence of macropores. Table 1 shows that GGHs-derived carbon BSAC-A-800 (1376.2 m 2 g À1 ) and BSAC-A-900 possess higher SSA (S BET ) than those of BSAC-A-700 and BSAC-A-1000.…”

“…It indicates, EDLC is an important class due to high specific surface area, tunable porous electrodes providing facile pathways for easy accessibility and transport of electrolyte ions, high electrical conductivity, and excellent electrochemical stability. [36] In a given particle of the porous material, the high surface area can be obtained by different sizes of pores or random distribution of pores. Depending on the diameter of the pores, it is categorized into subsets such as macropore, mesopore, and micropore.…”

There is a growing interest in supercapacitors as energy storage systems due to their high specific power, fast charge/discharge rates, and long cycling stability. Researchers have focused recently on developing nanomaterials to enhance the capacitive performance of supercapacitors. The inclusion of electroactive components, such as transition metal oxides (TMOs), carbonbased materials, and conducting polymers (CPs), is believed to play an important role in improving the electrochemical behavior of the electrode materials. Nevertheless, supercapacitors containing TMOs, carbon-based materials, and CPs commonly suffer from inferior ion-transport kinetics and poor electronic conductivity, which can affect the rate capability and cycling stability of the electrodes. Therefore, the development of TMO/CP and TMO/carbon-based electrode materials has gained widespread attention because they synergistically combine the advantages of both materials, enabling revolutionary applications in the electrochemical field. In general, TMOs have given good performance as electrodes for supercapacitors by further increasing the performance of the electrode when two metal cations are introduced into a single crystal structure. This Review describes and highlights recent progress in the development of bimetallic oxides regarding their design approach, configurations, and electrochemical properties for supercapacitor applications, at the same time providing new opportunities for future energy storage technologies.

“…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.
