Abstract
Flexible supercapacitor is in rising demand due to the limited applications of bulky and more sustainable energy storage devices for large scale device such as electric car and flexible wearable devices and consumer electronics. Currently, the energy storage devices in the market are heavy and bulky, hence lacking flexibility and not suitable for these relevant applications. In addition, energy storage device such as lithium-ion battery are relatively harmful to the environment compared to supercapacitor that produces lower pollution and maintenance cost and provides longer operating life and higher efficiency. These properties could lead to the increase in the market growth of supercapacitor, which drives the interest in its further development of flexible supercapacitor devices. In th...[

Flexible supercapacitor is in rising demand due to the limited applications of bulky and more sustainable energy storage devices for large scale device such as electric car and flexible wearable devices and consumer electronics. Currently, the energy storage devices in the market are heavy and bulky, hence lacking flexibility and not suitable for these relevant applications. In addition, energy storage device such as lithium-ion battery are relatively harmful to the environment compared to supercapacitor that produces lower pollution and maintenance cost and provides longer operating life and higher efficiency. These properties could lead to the increase in the market growth of supercapacitor, which drives the interest in its further development of flexible supercapacitor devices. In this project, the main objective is to fabricate a flexible & ultralight supercapacitor based on ultra-high molecular weight polyethylene (UHMWPE) membrane with excellent electrochemical performance. In order to achieve the goal, material characterization and process optimization of UHMWPE fabrication was performed, and supercapacitor device optimization was finally conducted and analysed.
