High-strength and high energy storage capacity
Source: Energy Daily
The research team led by Dr. Kim Tae-hoon of the Department of Functional Composites of the Composites Research Division at the Korea Institute of Materials Science (KIMS, President Jung-hwan Lee), a government-funded research institute under the Ministry of Science and ICT, succeeded in developing the world's first multifunctional carbon nanotube fiber which simultaneously achieves high energy storage capacity and high strength, together with the research team of Professor Yang Seung-Jae of Inha University (President Myung Woo Cho).
Most of the existing energy storage and structural materials have only one property between high strength or high energy storage capacity. By using carbon nanotube fiber that is light, strong, and has excellent electrical conductivity, the material developed by the two research teams has both properties simultaneously.
The research team applied surface treatment on carbon nanotube fibers and produced a high-strength fiber-type supercapacitor by inducing the growth of porous carbon. This enabled the synthesis of new fibrous material with energy storage properties while maintaining the strength of carbon nanotube fibers. The researchers confirmed that the fiber-type supercapacitor stably operates while supporting a heavyweight.
