Indigenous Biotextiles in the Philippines as Supercapacitor Electrodes

抄録

Supercapacitor is a promising device for the power storage. In the University of Santo Tomas, biomaterials have been extensively investigated for the electrode materials for supercapacitors.

Easily accessible energy is a necessity in the present world. While technology advances, more alternative sources of energy are discovered. With the fast-growing demand for energy and power, the development of energy storage devices, like batteries, capacitors, and super capacitors, is a clear solution.

The University of Santo Tomas Fabric Super capacitor Team utilized local Philippine natural fibers, such as pina, abaca, banana, and water hyacinth blended with polyester or cotton. These woven textiles coated with conducting polymers carbon nanotubes or rice straw biochar performed well as super capacitor electrode materials. The team gained wisdom from the challenges and successes of working with natural fabrics as energy storage devices. We hope that the materials from nature will be used in the near future.
