This study explored different compact packaging techniques and evaluated their impact on the performance of carbon nanotube (CNT)-based supercapacitors. The increasing demand for high-performance energy storage devices in compact applications has driven the need for efficient packaging and reliable testing methods. Supercapacitors, with their superior power density and long cycle life, hold immense potential for various electronic applications. Various packaging techniques, including coin cell, pouch cell, and chip-type supercapacitor, were employed in this research. Electrochemical characterization techniques such as cyclic voltammetry, impedance spectroscopy, and charge-discharge cycling were implemented to evaluate specific capacitance, power density, energy density, and series resistance. The performance of the supercapacitors was investigated under extreme conditions, including temperatures of -20 °C, 25 °C, and 60 °C. The study thoroughly examined the effects of crimp pressure on coin cell packaging. Additionally, novel design ideas for manufacturing miniature chip-type surface mount supercapacitors are proposed, aiming applications such as memory backup and portable electronic devices. Areal capacitance of 1298 mF/cm² was achieved, which was good compared to its counterparts. Overall, this research highlights the significance of packaging techniques and testing methodologies in enhancing the performance and reliability of CNT-based supercapacitors. The findings contribute to the development of next-generation energy storage systems capable of meeting the increasing demands of diverse industries and applications.
