“…Taking EWC‐2 as an example, these four peaks are at 398.3, 399.6, 400.6 and 401.9 eV. As shown in Figure S1f, the content of pyridinic N and pyrrolic N of EWC‐1 and EWC‐3 is higher, which is beneficial to boosting the electrochemical performance and also providing the pseudo‐capacitances in carbon materials . Compared with other materials, the content of the various nitrogen types in EWC‐2 is relatively uniform, wherein the content of the quaternary N is the most, improving the electric conductivity of carbon materials …”

Using egg white as raw material, the activated carbon materials with nitrogen doping were synthesized by a two‐step method involving carbonization and activation. Structure characterization showed this porous carbon had a three‐dimensional honeycomb structure composed of interconnected micropores and mesopores, which resulted in a high specific surface area of 2918 m2 g−1. Due to KOH activation, the appropriate ratio of micropore to mesopore could optimize the diffusion channel of electrolyte ion and increase the contact area between electrolyte and electrode. Thus the egg white‐derived porous carbon (EWC) showed outstanding electrochemical properties as supercapacitor electrode. In three‐electrode system, a high specific capacitance of 335 F g−1 could be achieved at a current density of 0.5 A g−1, and only 8.3% of capacitance was lost after 10000 cycles. For the symmetrical supercapacitor fabricated with as‐prepared carbon material, it exhibited a specific capacitance of 68 F g−1 and a maximum energy density of 13.6 W h kg−1.

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 ...

3D hierarchical porous carbon consisting of micropores, mesopores and macropores was successfully prepared through the activation of chestnut shell via KHCO 3 . The influence of KHCO 3 /chestnut shell ratio on the textural properties was carefully investigated and the structure, micrographs, and surface chemical status of the materials were expressed via X-Ray diffraction (XRD), transmission electron micrographs (TEM), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), respectively. With the optimized amount of KHCO 3 , high specific pore surface area (2298 m 2 g -1 ) and high total pore volume (1.51 cm 3 g -1 ) were achieved, endowing an advantageous electrochemical characteristics for the electrode as ultracapacitors in three-electrode system. At 2 A g -1 , a high specific electric capacity of 387 F g -1 was reached. The remarkable electrochemical performances are mainly due to hierarchical porous structure with the high specific surface area (SSA) and the eminent total pore volume. It means that this hierarchical porous carbon prepared by activated by using KHCO 3 would have more promising foreground in the field of energy storage.
