Abstract

The sustainable conversion of biomass derived from low-cost agro waste into useful products is gaining popularity as global attention shifts towards green initiatives and energy efficiency. Coconut shell is considered as a potential raw material to synthesise carbon by burning it in a controlled atmosphere followed by physical / chemical activation. Various methods have been used to produce activated carbon from coconut shell. Production of graphitic carbon, which is preferred over activated carbon in supercapacitor applications, is a time consuming process and literature on the same from coconut shell is scanty. In this work, the graphitic carbon is produced rapidly and environment friendly by processing the coconut shell in thermal plasma and its potential use in energy storage applications are explored. Chemical composition, specific surface area, pore volume and average pore diameter of synthesized carbons are analyzed. An electrode for the supercapacitor is prepared from this material and electrochemical studies are performed. The specific capacitance and its retention as well as power and energy densities are notable and compared with previously published results.

以椰子壳废料为原料,用电弧等离子体快速绿色合成高性能对称超级电容器用石墨碳
随着全球注意力转向绿色倡议和能源效率,从低成本农业废物中提取的生物质可持续转化为有用产品的做法越来越受欢迎。椰子壳被认为是一种潜在的原料,通过在受控的大气中燃烧,然后进行物理/化学活化来合成碳。从椰子壳中提取活性炭的方法多种多样。石墨炭的生产是一个耗时的过程,而在超级电容器应用中石墨炭比活性炭更受欢迎,而且从椰子壳中生产石墨炭的文献很少。本研究通过热等离子体处理椰子壳制备了快速环保的石墨碳,并探讨了石墨碳在储能方面的潜在应用。分析了合成碳的化学成分、比表面积、孔体积和平均孔径。用该材料制备了超级电容器的电极,并进行了电化学研究。与先前发表的结果相比,比电容及其保持率以及功率和能量密度都是显著的。
