DESCRIPTION:Speakers: Gorata Pearl Morake ()\nIntroduction\nDue to over re
 liance of fossil resources for fuel and chemicals\, the resultant global w
 arming and pollution has led to research being conducted on other alternat
 ives for renewable energy and storage systems that can be produced using m
 ore sustainable methods. This involves the development of storage systems 
 that have a high energy density and a long-life span (Batteries\, supercap
 acitors and solar cells). Batteries have high energy capacity\, but they a
 re limited by their low power density and low cycle life. A supercapacitor
  possesses unique qualities of high-power density\, high cycle stability\,
  and rapid charge-discharge performance but a low energy density.\nSuperca
 pacitors can be evaluated based on their electrode material 
 and electrolyte performance. The energy density is largely determined by
  the electrode materials. As such\, studies on improving the performance o
 f electrodes via the development of new electrode materials are increasing
 . Biomass has been sought as a substrate for carbon electrode materials. T
 his study therefore explores porous carbon derived from Sweet Sorghum Stal
 k to make supercapacitor electrodes that exhibit long cycling life\, high 
 specific capacitance when implored in a two-electrode system.\n\n2. Result
