“…The pseudocapacitance (C p ) and charge separation resistance (R p ) connected in a parallel circuit refer to the ideal capacitive behavior in which the Nyquist plot ideally forms a straight line parallel to the y-axis. 69 The tting curves for the Nyquist plots coincide well with the experimental values (with less than 5% error), suggesting that the proposed equivalent circuit model will reect the actual electrochemical processes occurring within the hybrid protein based NFC/RGO supercapacitors. The circuit parameters obtained aer tting the equivalent circuit model are mentioned in Table S2.…”

“…There was a noteworthy decrease in the R S and R ct maybe because of the improved available surface area during the continuous chargedischarge cycles which can enhance the SC performance. [63,64] However, the extended cycling test of the AEHC device still maintained the capacitance retention of 95.7% even after 16 000 cycles. After the completion of the cycling test, the EIS analysis of the AEHC device was performed.…”

much attention because of their advantages of quick charge/discharge property, superior power density, and long-lasting and eco-friendly feature. [3,4] However, active materials which consist of inherent synergistic properties should be chosen to improve the capacity performance in the SCs. Typically, the active materials (Faradaic redox nature) are constructed with transition metal oxides/hydroxides and chalcogenides. [5] The fabricated electrodes with transition metal oxides/hydroxides show great redox properties and possess high theoretical capacitance values, but these electrodes often reveal low rate performance and poor cycling capability. [6] Hence, it urges engineer to develop innovative composite materials which can offer synergistic characteristics and enriched electrochemical properties. This is more favorable for the development of highperformance SCs. [7,8] Recently, transition metal compositions (Ni, Fe, Cu, Mn, Co, etc.) consisting of sulfides, [9] selenides, [10] and phosphides [11] exhibit excellent electrochemical properties. These materials are promising substitutes to typical hydroxides/oxides owing to the plenty of active channels, robust structural capability, and better electrical conductivity. The energy storage capability of SCs is mainly influenced by the material composition of electrodes. Based on the previously published literature, the SCs with multi-metal chalcogenides show higher charge storage performance compared to single metal chalcogenides. Moreover, it is highly important to mention that the compositional metal chalcogenides allow inherent electrochemical sites and enriched redox properties due to various metal ion species during electrochemical analysis. These features are more favorable to improve electrochemical performance and cycling lifetime. [12][13][14] Especially, the substitute of hydroxide/oxides with sulfur provides flexibility to material structures owing to its low electronegativity property. Consequently, morphological structures of materials alleviate changes occurring in its morphology during the electrochemical analysis. [9,15] Therefore, evolving the combined metal chalcogenide electrodes with advanced characteristics such as good conductivity andThe ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/smll.202105185.

“…SCs have the capability to work at very low temperatures, a unique quality that knocks down the choice of several types of batteries as a better device for energy applications. [1][2][3]41,42 SCs store charges electrostatically, unlike through reversible chemical reactions for rechargeable batteries. They can be discharged and recharged up to a very high number of cycles without losing their capacitance.…”

In this research study, we have presented a simple two-step synthesis path to producing a cost-effective, highporosity carbon material via acidic dehydration of white sugar. The electrochemical behavior of the activated sugar-based carbon material (ASC), activated at 400 °C (ASC 400) and adopted as a supercapacitor electrode in a symmetric device, demonstrated a limit specific capacitance of 242.67 F g −1 at 1 A g −1 . The device also demonstrated a good efficacy as an established material for supercapacitors suitable for high-power applications with a satisfactory energy density of 19 Wh kg −1 and a power density of 750 W kg −1 at a gravimetric specific current of 1 A g −1 . The results obtained provide a potential route to converting cheap refined biomass sources into highly porous nanostructured materials for energy-storage device applications.
