“…5d, the curves of N-O-HPC-3 at different current densities display triangular symmetry, implying highly reversible charge-discharge behavior. Amazingly, compared with the other state-of-the-art values reported in the recent literatures (Table 2), 28,[63][64][65][66][67][68][69][70][71][72][73][74] the N-O-HPC-3 in this work displays the highest specic capacitance, owning to its largest specic surface area with 3D hierarchically porous structure and N and O co-doping. To further investigate the electrochemical performances of as-prepared N-O-HPC-3, the N-O-HPC-3//N-O-HPC-3 symmetric SCs were assembled and tested in a two-electrode system (Fig.…”

“…Several sources of bio-waste such as animal, mineral, plant, and vegetables etc. have been reported in the literature as base materials for activated carbon production for application as an electrode material for electrochemical energy systems [86,[94][95][96][97][98][99][100][101][102][103][104][105][106][107][108][109]. Several types of electrodes have been tried and the most common systems today are built on the electrochemical double-layer capacitor that is carbon-based, has an organic electrolyte, and is easy to manufacture.…”

The demand for renewable energy sources worldwide has gained tremendous research attention over the past decades. Technologies such as wind and solar have been widely researched and reported in the literature. However, economical use of these technologies has not been widespread due partly to cost and the inability for service during of-source periods. To make these technologies more competitive, research into energy storage systems has intensified over the last few decades. The idea is to devise an energy storage system that allows for storage of electricity during lean hours at a relatively cheaper value and delivery later. Energy storage and delivery technologies such as supercapacitors can store and deliver energy at a very fast rate, offering high current in a short duration. The past decade has witnessed a rapid growth in research and development in supercapacitor technology. Several electrochemical properties of the electrode material and electrolyte have been reported in the literature. Supercapacitor electrode materials such as carbon and carbon-based materials have received increasing attention because of their high specific surface area, good electrical conductivity and excellent stability in harsh environments etc. In recent years, there has been an increasing interest in biomass-derived activated carbons as an electrode material for supercapacitor applications. The development of an alternative supercapacitor electrode material from biowaste serves two main purposes: (1) It helps with waste disposal; converting waste to a useful product, and (2) it provides an economic argument for the substantiality of supercapacitor technology. This article reviews recent developments in carbon and carbon-based materials derived from biowaste for supercapacitor technology. A comparison between the various storage mechanisms and electrochemical performance of electrodes derived from biowaste is presented.Sustainability 2019, 11, 414 2 of 22 renewable energy sources such as solar energy, geothermal energy, wind energy, biofuels, etc., while electrochemical energy storage devices such as supercapacitors, rechargeable batteries, etc. have also attracted significant research [9][10][11]. It is not an overstatement to say that successful development of any renewable energy source (e.g., windmills and solar cells), hybrid and electric vehicles and smart grids depend significantly upon the availability of a suitable energy storage system. A considerable amount of literature has been published on the use of supercapacitors as a viable storage device for renewable energy. Over 20,000 articles, books etc. were published in 2017, a higher number of research work is projected for 2018 (data from google scholar). There has been a geometric increase in the research published since the year 2000. Since supercapacitors were first experimented in 1957 by engineers at General Electric, they have found commercial applications in portable electronics, transportation and aerospace industry [12,13]. These applications of supercapacitors ...

“…Therefore, of late, due emphasis has also been laid on the evolution of eco-friendly supercapacitors. Benign materials retrieved from carbon-rich agricultural and food biowaste, [9,105,115,116] industrial waste, [76][77][78][79] paper, [74,80,81] and cotton [82] have been used in their fabrication. Additionally, carbon acquired from discarded polymers [83][84][85][86][87][88][89][90][91][92][93][94][95] as well as valuable metals and metal composites recuperated from electronic waste including spent batteries [96][97][98][99][100][101][102] have been utilized in the preparation of supercapacitor electrodes.…”

Supercapacitors store electrical energy on the basis of electrostatic attraction between opposite charges as a result of the formation of an electric double layer (EDL) at the electrolyte/electrode interface. Carbon-derived materials are commonly used to fabricate supercapacitor electrodes owing to their high electrical conductivity, high capacitance, excellent porosity, good electrochemical stability, and large specific surface area. [131-136] Predominantly, these materials include carbon nanotubes (CNTs), graphene, carbon spheres, hollow carbon spheres, carbon nanoparticles (CNPs), etc. [62,137-145] Nevertheless, they fail to demonstrate the desirable performance in practical applications after a certain threshold owing to their short durability and low energy density. Although, metal-organic frameworks (MOFs) have proven to be better electrode candidates in certain aspects, [142,143,146-148] however, these materials incur high cost, low yield of porous carbon, high consumption of metallic nitrate, [62] and hence higher waste generation. Due to the rising concerns of waste production and its management and hence the need for sustainable and cheap resources, reusing and/or converting waste from various sources such as industrial, agricultural, food, and spent electronic devices efficiently into usable carbon has attracted much interest since recently.
