Unzipped MWCNT/polypyrrole hybrid composites: a pathway to high-performance asymmetric supercapacitors
Shilpa Simon, Letcy Theresa, P.B. Sreeja
Abstract
Unzipped MWCNTs (UzMWCNTs) were synthesized via a modified Hummer’s method. UzMWCNT/PPy achieved 944 F g −1 with 92% retention (5000 cycles). UzMWCNT/PPy//AC supercapacitors exhibited 400 F g −1 at 1 A g −1 with 95% retention, highlighting their energy storage potential.
