Effect of Adding Activated Carbon of Palm Kernel Shell on Carbon Papers as Electrochemical Double Layer Capacitors

[摘要] The activated carbon from palm kernel shell has been activated using NaOH at 400 ?C. The activated carbon sample has been characterized using FT-IR spectroscopy, X-ray diffraction and scanning electron microscopy techniques to be used as carbon electrodes in Electrochemical Double Layer Capacitors (EDLC). Addition of activated carbon of palm kernel shell with 45 μm particle size on carbon paper as electrode at EDLC with mass ratio between carbon paper and activated carbon of palm kernell shell 1: 4, plate surface area 3 x 11 cm2, concentration of electrolyte solution of H3PO4 is 0,6 N and charge time of 30 minutes can improve EDLC ability to store charge up to 387.14 μF and conductivity values of 52.2811x10-5, Ω-1cm-1.The desired capacitive performance of waste from palm kernel shells can be a source of carbon material biomass for high performance EDLC and low-cost energy storage devices.
