To address the growing need for high-performing and stable energy storage devices, optimizing durability structure of supercapacitor electrodes is crucial. Traditional frequently face challenges in achieving an optimal balance between electrochemical capacity structural stability. This study presents synthesis TiO2/CC@C array through ultrasonic disorder-induced deposition (UDID), specifically applications. The impact different power levels (50-200 W) on electrodes' properties was systematically examined. SEM analysis indicated that sample prepared at 150 W showed optimal, densely packed TiO2 nanorods with improved surface uniformity, facilitating efficient ion transport. displayed a 46.73 m2/g specific area mean pore diameter 9.35 nm, contributing to charge capacity. Raman spectroscopic further confirmed successful composite, revealing distinct carbon-related peaks. Electrochemical measurements this electrode attained capacitance 687.3F/g scan rate equal 5 mV/s. system delivered density 158.4 Wh/kg 20 W/kg when assembled as asymmetric (ASC) AC positive electrode. Furthermore, after 10,000 cycles, it maintained 86.3 % its initial demonstrating outstanding cycling These findings indicate significantly improves both performance TiO2/CC@C, making promising candidate advanced
