Mini Review of Technological Trends of Flexible Supercapacitors Using Carbon Nanotubes

With the technological advances in wearable and portable electronic devices, demands for associated technologies including flexible energy storage devices increase. Among many types of supercapacitors (FSCs) are highly attractive comparison with others as they exhibit high power density, mechanical stability. In particular, carbon nanotubes (CNTs) being widely used electrode materials FSCs, owing to their strength outstanding electrical performance. Herein, we classified CNT-based FSCs according structural CNTs incorporated. The unique structures properties three (single-walled (SWCNT), double-walled (DWCNT), multi-walled (MWCNT)) compared mechanisms discussed. Finally, a summary overall electrochemical current development reported FSC electrodes based on SWCNT, DWCNT, MWCNT presented thoroughly.
