2D Nanomaterial Thin-films for Wearable Supercapacitor (Energy Storage) Device
Demanding quality of human life, bendable and implantable electronic devices such as health care sensors (hearing aids, BP/glucose meters), digital watches, bendable smartphones, LEDs, and intelligent clothes have led to the evolution of flexible energy storage systems. To operate these electronic gadgets, we developed a cost-effective and lead-free wearable supercapacitor (energy storage) device that can store electrical charge with a capacity better than a conventional battery. We recently communicated this research work for publication in a peer-reviewed international journal, advanced energy materials.
In this project, we used physical and chemical methods of thin film deposition to synthesize a composite material thin film with Molybdenum Disulfide (MoS2) and MXene (Ti3C2Tx) over carbon cloth. Our developed bendable supercapacitor device exhibits higher specific capacitance/capacity (215 F g-1at 5 mV s-1) with a working voltage of 1 V (series connection can match the power requirements). It can work even after bending up to 160° angle. We proposed a cost-effective method to reduce the manufacturing cost that can be integrated into wearable electronics on a large scale.
