Demand for high performance energy storage application is higher than ever. CNT is known to be a great material in enhancing high performance energy storage due to its capacitance characteristics. Nevertheless, the production of CNT that is functionalized for capacitance performance is still relatively expensive using conventional method. By using flame-assisted furnace, CNT production cost is reduced due to minimal furnace temperature and higher growth rate of CNT due to natural decomposition of hydrocarbon through combustion process. Furthermore, using the proposed process, CNT can be synthesized enhanced capacitance properties through manipulation of flame parameters. As a result, a huge walled CNT with a nominal diameter and length of 30 nm and 100 microns are produced at a high growth rate. Characterization of the nanotubes confirms the good quality and crystallinity of the CNT produced with enhanced capacitance characteristics.
As mobile electronics become more and more ubiquitous in the society, the demand for high performance flexible energy storage is high. Supercapacitor total market value which is currently at USD 5 billion is expected to reach USD 22.5 billion by the end of 2028. Nevertheless, supercapacitor performance continues to improve through R&D. One of the most significant breakthroughs is application of CNT based supercapacitor which will be able to significantly improve the storage and discharge capability of supercapacitor. Unfortunately, application of CNT in supercapacitor is limited by the high production cost of CNT using furnace.
The business model that we propose focuses on 2 market segments that require production of a
small scale with the lab-based plant for academics and R&D, while large scale for energy storage manufacturers.
The low-cost process can produce CNT at a competitive prices.
