Development of Carbon Nanotube Yarn Supercapacitors and Energy Storage for Integrated Structural Health Monitoring
Abstract
Developing efficient, sustainable, and high-performance energy storage systems is essential for
advancing various industries, including integrated structural health monitoring. Carbon nanotube
(CNT) yarn supercapacitors have the potential to be an excellent solution for this purpose because
they offer unique material properties such as high capacitance, electrical conductivity, and energy
and power density. This study aimed to develop CNTY supercapacitors that can be integrated into
polymeric and composite materials to power CNTY sensors that can measure current density,
voltage, time charge, and discharge. The focus of this study was on the fabrication,
characterization, and exploration of various configurations that could come from using CNT yarn
supercapacitors to integrated structural health monitoring while also examining its development
process involving carbon nanotubes' synthesis formations, preparing electrodes, and then
assembling a supercapacitor. These capacitors are extraordinary with their characteristics
displaying a very high-power density and rapid charge/discharge rates accompanied by exceptional
cycling stability, making them perfect for use within integrated structural health monitors where
efficiency in storing energy matters, just like having lightweight components, which remains
crucial. Those included fabricating the supercapacitors using various materials, characterizing
them to determine the capacitive properties, energy, and power densities, integrating them to
power the sensors, and allowing data acquisition from the latter. Initially, experimental studies
were conducted to investigate the energy density and power density behavior of CNTYs embedded
in various electrochemical-active matrices to monitor the matrices' power process and the CNTY
supercapacitors' life-cyclic response.
