Bulletin Board: UST’s textile supercapacitor wins 1st place at PAASE symposium

In response to the growing need for sustainable energy storage technologies, University of Santo Tomas researchers developed a supercapacitor using abaca-cotton fabric.

UST Graduate School student Celine Grace V. Causapin, along with College of Science faculty researchers Dr. Felicidad Christina R. Ramirez and Dr. Christina A. Binag, fabricated the textile supercapacitor with multi-walled carbon nanotubes (MWCNTs) and polyaniline-polypyrrole complex layer (PAPY) as electrode materials. 

Their research won first place in the Scientific Posters category of the Rapid Fire Competition during the 40th Philippine-American Academy of Science and Engineering (PAASE) Anniversary and 2020 Annual Scientific Meeting and Symposium on August 14.

The study was able to show that “the energy density (1.82 Wh/L) and power density (50.31 W/L) values of PAPY/MWCNT/abaca-cotton fabric fall well within the supercapacitor range of the Ragone plot, indicative of an ideal supercapacitor electrode material behavior.”

The abaca-cotton fabric, though non-conducting, has a high surface area and is suitably porous for supercapacitors, while MWCNTs have high conductivity and stability but low capacitance.

PAPY, meanwhile, complements the other materials with its good conductivity, improved cycling stability, and high capacitance values.

In a statement, UST said supercapacitors with these electrode materials are “capable of storing and delivering energy, enough to power a 2.88 V LED” and can be used to power a variety of low power devices such as PC cards, portable media players, and flashlights. 

Other potential applications of this textile-based supercapacitor are in off-grid or rural areas, as well as assistance during and after major calamities.
