Effect of Temperature on Physical and Electrochemical Properties of the Monolithic Carbon-Based Bamboo Leaf to Enhanced Surface Area and Specific Capacitance of the Supercapacitor

摘要

Several analysis have been conducted on the physical and electrochemical properties of monolithiccarbon-based bamboo leaf for supercapacitor application. Therefore, the main focus of this study wasto analyze the relationship between pore diameter, surface area, and specific capacitance. Thevariations of pore diameter were found using the activation temperature in the range of 750 °C, 800 °C,850 °C, and 900 °C. The carbon electrode was prepared in the monolithic form to ensure there is nodisturbance with the natural pore of the electrode in the presence of adhesives. The physical propertiesanalyzed include (i) thermal properties, (ii) surface morphology, (iii) elemental content (iv)crystallinity properties and (v) N 2 gas adsorption-desorption isotherm. Furthermore, the specificcapacitance was determined through the use of Cyclic Voltammetry (CV) as the electrochemicalcharacteristic. It was discovered that the specific capacitance varies with average pore diameter suchthat a higher specific capacitance was found with pore diameters smaller than 1.5 nm and the valueincreased with the size. This research was supported by analysis of surface morphology, elementalcontent, thermal resistance, and degree of crystallinity.
