Development of Disposable and Flexible Supercapacitor Based on Carbonaceous and Ecofriendly Materials
A novel flexible supercapacitor device was developed from a polyethylene terephthalate substrate, reused from beverage bottles, and a conductive ink based on carbon black (CB) and cellulose acetate (CA). The weight composition of the conductive ink was evaluated to determine the best mass percentage...

| description | A novel flexible supercapacitor device was developed from a polyethylene terephthalate substrate, reused from beverage bottles, and a conductive ink based on carbon black (CB) and cellulose acetate (CA). The weight composition of the conductive ink was evaluated to determine the best mass percentage ratio between CB and CA in terms of capacitive behavior. The evaluation was performed by using different electrochemical techniques: cyclic voltammetry, obtaining the highest capacitance value for the device with the 66.7/33.3 wt% CB/CA in a basic H<sub>2</sub>SO<sub>4</sub> solution, reaching 135.64 F g<sup>−1</sup>. The device was applied in potentiostatic charge/discharge measurements, achieving values of 2.45 Wh kg<sup>−1</sup> for specific energy and around 1000 W kg<sup>−1</sup> for specific power. Therefore, corroborated with electrochemical impedance spectroscopy assays, the relatively low-price proposed device presented a suitable performance for application as supercapacitors, being manufactured from reused materials, contributing to the energy storage field enhancement. |
