Harnessing new materials for developing high-energy storage devices set off research in the field of organic supercapacitors. Various attractive properties like high energy density, lower device weight, excellent cycling stability, and impressive pseudocapacitive nature make organic supercapacitors suitable candidates for high-end storage device applications. This review highlights the overall progress and future of organic supercapacitors. Sustainable energy production and storage depend on low cost, large supercapacitor packs with high energy density. Organic supercapacitors with high pseudocapacitance, lightweight form factor, and higher device potential are alternatives to other energy storage devices. There are many recent ongoing research works that focus on organic electrolytes along with the material aspect of organic supercapacitors. This review summarizes the current research status and the chemistry behind the storage mechanism in organic supercapacitors to overcome the challenges and achieve superior performance for future opportunities.

“…The electrochemical properties of AC obtained from rice straw and eucalyptus wood biomasses are studied in a three‐electrode set‐up. The neutral aqueous electrolyte (2 M NaCl) has been used, as the acidic and alkaline electrolytes are associated with evolution of H 2 or O 2 gases when operated at larger potential window and may affect the stability of the electrode materials in device operation 28 . Besides, ionic liquid‐based non‐aqueous electrolyte has been explored here to achieve higher energy density requirement by virtue of their ability to operate the device at a wider potential range.…”

Activated carbon derived from biomasses with different oxygen‐bearing chemical constituents has been explored as supercapacitor electrode. The rice straw (RS) and eucalyptus wood biomasses were selected owing to their contrasting composition of cellulose, hemicellulose, and lignin contents. The activated carbons of these biomasses are obtained by pyrolysis at 550°C followed by thermal activation (700°C) after treatment with optimized KOH. The specific capacitance of RS‐based activated carbon (ACRS‐700), measured from galvanostatic charging‐discharging studies at 0.5 A g−1, is much higher (eg, 365 F g−1) than that of ACEW‐700 (168 F g−1). The higher specific capacitance of ACRS‐700 is attributable to: (i) significantly higher surface area (3345 m2 g−1) comprising of interconnected micro‐ and mesoporous structure; (ii) porosity of about 2.0 cm3/g; and (iii) oxygen‐rich hemicellulose contents. The possible charge storage mechanism in ACRS‐700 has been discussed. The real‐time application of ACRS‐700 has been demonstrated by lighting up red LEDs using ACRS‐700//ACRS‐700 symmetric supercapacitor device, operated with aqueous and freshly synthesized [Bu4N+][NO3−] ionic liquid as electrolytes. The maximum energy density (42.7 Wh kg−1) and the power density (1.9 kW kg−1) for ionic liquid electrolyte are favourable for supercapacitor applications.
