“…The electrochemical measurements of the supercapacitors and electrode including CV, EIS and GCD were carried out by electrochemical workstation (Zahner Zenium, Germany). For obtaining the value of the speci c capacitance (F g − 1 ) from the GCD curve, the calculation equation [4,5] is: where I (A) is the discharge current, ∆t (s) is the discharge time, m (g) is the mass of active material and ∆V is the width of the potential window for a full discharge.…”

“…The biomass materials are gradually replacing fossil fuels to become the promising materials in the context of exhausted fossil fuels. Nowadays, the biomass derived porous carbon is centrally researched for energy storage as fuel cell, batteries and supercapacitors due to abundant source, easy harvesting and stable output [1][2][3][4][5]. Among them, the porous carbon materials for the electrodes in the supercapacitors have attracted intensive research recently due to replace the commercial activated carbon from charcoal with low conductivity, low speci c surface area and negative effects on the environment.…”

Three-dimensional (3D) porous carbon material enhances the electrochemical performance of symmetrical solid-state supercapacitors which are prepared by using abundant biomass waste as electrodes and (PVA-Li2SO4) gel polymer electrolyte. A saving and simple carbonization method with KOH chemical activation is developed for synthesizing highly porous carbon from peanut shell with high specific surface area of 1348 m2 g–1, which can be reused the chemical activation solution. The electrodes making by such three-dimensional porous carbon in a 1 M Li2SO4 electrolyte demonstrates a maximum specific capacitance of 386 F g–1 at current density of 2 A g–1, energy density and power density of 53.61 Wh k g–1 and 1000 W kg–1, respectively. The symmetrical solid state supercapacitors with sandwich structure of (3D porous carbon P/PVA-Li2SO4/3D porous carbon P) exhibits a maximum specific capacitance of 116 F g-1 at current density of 0.5 A g–1. The energy density and power density are the value of 9 W h kg–1 and 380 W kg–1, respectively. Further, the supercapacitors also demonstrate good cycling stability 89 % retention after 7000 cycles.

In the recent times research towards solid state supercapacitors (SSS) have increased drastically due to the promising performance in futuristic technologies particularly in portable and flexible electronics like smart watches, smart fabrics, foldable smartphones and tablets. Also, when compared to supercapacitors using liquid electrolyte, solid electrolyte has several advantages like high energy density, safety, high cycle life, flexible form factor, and less environmental impact. The crucial factor determining the sustainability of a technology is the eco‐friendliness since the natural resources are being exploited in a wide scale. Numerous studies have focused on biodegradable materials for supercapacitor electrodes, electrolytes, and other inactive components. Making use of these biodegradable materials to design a SSS enables the technology to sustain for a very long time since biodegradable materials are not only environment friendly but also, they show relatively high performance. This review focuses on recent progress of different biodegradable electrodes, and electrolytes along with their properties, electrochemical performance and biodegradable capabilities for SSS have been analyzed and provides a concise summary enabling readers to understand the importance of biodegradable materials and to narrow down the research in a more rational way.
