摘要
Based on the growing demand for efficient energy storage, studies have focused on enhancing supercapacitors by utilizing natural fibers like cotton, which offer economic and environmental benefits. This study explores the incorporation of nickel into cotton textile-based electrodes impregnated with activated carbon (AC) to improve their electrochemical performance. Comparative analysis between Ni coated AC-cotton and AC-cotton supercapacitors demonstrated significant performance improvements due to Ni incorporation. The results showed that Ni-coated electrodes exhibit higher capacitance (144.7 mF center dot cm(-2)) than Ni-free electrodes (63.27 mF center dot cm(-2)), higher energy density (38.28 mu Wh center dot cm(-2) vs 9.467 mu Wh center dot cm(-2)), and superior capacitance retention (90.64 %) compared to their Ni-free counterparts (73.59 %), confirming the critical role of Ni in enhancing supercapacitor efficiency and durability.
