Summary Activated carbon, from biomass (pinecone), was synthesized by conventional pyrolysis/chemical activation process and utilized for the fabrication of supercapacitor electrodes. The pinecone‐activated carbon synthesized with 1:4 ratio of KOH (PAC4) showed an increase in surface area and pore d...
