Abstract
Supercapacitor has been widely used to provide a power source for the excess that has a large charge storage capacitance and power density. One of the important properties that must be possessed by electrode supercapacitor is having high electrical conductivity. Zeolite with silica base material of rice husk (sodium silicate) and alumina(sodium aluminate) using sol-gel method with volume ratio 5:1 has been prepared. Zeolite samples were made in pellets and thermally treated 150 °C, 250 °C and 350°C, then characterized using Scanning Electron Microscopy (SEM) and Inductance, Capacitance, and Resistance (LCR) meter. SEM characterization is conducted to obtain information of microstructure including the particle size, pore, and grains of zeolite. Small particle size and large pore size produce high electrical conductivity, while the small grain size can degrade its electrical conductiv ity. The highest electrical properties of zeolite obtained in 250 °C of 1.5540 x10 -4 S/cm. At temperature 250 °C pore size and grain size support the value of their electrical conductivity,respectively amounted to 2.400 to 8.000 μm and 1.800 to 10.400 μm. Based on the result of electrical conductivity values, it indicates that zeolite is included in the semiconductor and has potential as a supercapacitor electrode.
