“…In the three-electrode system and SSC device, the specific capacitance from CV curves was determined by eq : C sp = ∫ V 1 V 2 i d v m ϑ false( normalΔ V false) Here, C sp is the specific capacitance (F g –1 ), m refers to the mass of electrode, ϑ is the potential scan rate (V s –1 ), and Δ V refers to the potential window (V). Similarly, from GCD cycles, the specific capacitance was obtained by using eq : C sp = i t m Δ V Here, C sp is the specific capacitance (F g –1 ), i corresponds to the constant discharge current, t refers to the discharge time, m is the mass of the active material, and Δ V is assigned to the potential window.…”

The production of value-added materials from waste resources is a sustainable approach for solid waste management. Facile yet economic conversion of carbon-neutral biowastes into a metal-free porous carbon material with a high oxygen reduction reaction (ORR) and capacitive energy storage efficiency is critical for renewable energy conversion and storage technologies. Herein, a microporous carbon with a self-doped N heteroatom (ALPC) was successfully prepared from waste agarwood leaves through a chemical activation process. The synthesized ALPC-800 material containing N (11.23 atom %) and O (8.54 atom %) with a high surface area as an electrocatalyst for ORR shows an onset potential (E onset ) of 0.98 V and excellent limiting current density (J L ) of 6.09 mA cm −2 , which are comparable to 10 wt % Pt/C. ALPC-800 as an electrocatalyst shows a four-electron transfer-mediated ORR process which is supported by both experimental and theoretical findings. Also, ALPC-800 in a threeelectrode configuration for supercapacitors presented a high specific capacitance of 421 F g −1 at a current density of 1 A g −1 in an acidic electrolyte. More prominently, the assembled symmetrical supercapacitor device based on ALPC-800 demonstrated a high capacitance retention of 91% after 6000 cycles at 1 A g −1 with a remarkable energy density of 21.15 Wh kg −1 and a power density of 4.93 kW kg −1 . Thus, this work provides an environmentally benign, simple, efficient, and economical method for energy storage and conversion applications. Being a metal-free catalyst, heteroatom-doped ALPC-800 carbon material synthesized from biowaste has the potential to replace the commercially available high-cost Pt/C catalyst for fuel cell application.

Advancement of the voltage window with stringent safety concerns is an imperative strategy to enhance the energy densities and output power delivery of electrical double‐layer capacitors (EDLCs). Solid‐state, water‐in‐salt (WIS), and ionic liquid‐based electrolytes are attractive and ideal choices for high‐voltage EDLCs due to their superior voltage window, electrochemical performance, and predominant safety aspects. Mindful of this, the current report demonstrates the electrochemical performance of new nanoporous carbon electrodes derived from waste dry leaves of Swietenia macrophylla with a high specific surface area (SSA) (1834 m2 g−1) in polymer–gel, WIS, and ionic liquids‐based electrolytes. Symmetric EDLC devices are fabricated using polymer gel solid‐state (PVA–Na2SO4), ionic liquids (EMIMBF4), and WIS (21 m LiTFSI) electrolytes with the electrochemical stability windows of (ESW) 2, 2.5, and 2 V, respectively. The assembled devices with Na2SO4/PVA, EMIMBF4, and 21 m LiTFSI (WIS) electrolytes‐based devices exhibit high energy densities of 40, 31, and 25 Wh kg−1 at 0.5 A g−1 and good output power delivery of 5, 6.23, and 3 kW kg−1 at 5 A g−1 with better cyclability features. Self‐discharging studies and systematic evaluation of high‐voltage EDLCs offer a sustainable method to develop high‐performance aqueous and diverse electrolyte‐based supercapacitors.

“…Recently, different electrode and electrolyte nanomaterials were developed for device fabrication, keeping the portability and leakage issue problems in mind. Flexible, foldable, wearable, and stretchable electrode nanomaterials are available like graphene, graphene oxide, cotton, polysaccharides, carbon cloth, materials derived from biomass like rice husk, hyperlinked nanocellulose, tamarind leaf, jute fiber, agricultural waste, etc. − Among all of these, cotton and cotton-derived electrodes are the best choices because of their flexibility properties and can be used directly as a separator in an electrochemical device . The cotton precursors are very important because the cotton biomass consists of heteroatoms like oxygen, which enhance the active sites in the material.…”

The demand for renewable-energy-based efficient systems is a practical indication to develop sustainable energy nanomaterials for energy storage and conversion to reduce the use of pollution-based nonrenewable energy systems. The use of biomass-derived energy components is a new age for the development of sustainable energy electrode nanomaterials. Among biomass, cotton-based electrodes are more popular, as they are cost-effective and efficient energy materials. Cotton-plant-derived porous or pristine nanocarbons have good textural and morphological properties with high specific surface area, hierarchical porous structure, and large pore volume. The functionalization, addition of active moieties, and easy synthetic routes improve the properties and enhance the performance of various electronic devices. The functionalization of derived materials with a heteroatom perturbs the electrical neutrality of the framework. The incorporation of active sites enhances the surface area and creates defects in the framework. These properties speed up the charge storage and energy conversion reaction for better performance of fabricated devices. This Review gives a detailed understanding and advancements about cotton-derived energy nanomaterial. Also, it gives insight about the key factors affecting the performance of cotton-based electrodes, electrolytes, and other components of energy devices. This Review concludes with the cotton-plant-derived supercapacitor, fuel cell, and battery, with a deep insight into their physicochemical properties. This Review also discusses the role of the active mass of the material used for the different device fabrications, which alters the performance. Further, a deep insight has been provided with a brief discussion of other electronic devices like photovoltaic, triboelectric, and piezoelectric devices based on cotton-derived nanocarbon.
