Overview

• The novel supercapacitor combines single-walled carbon nanotubes (CNTs) with polyaniline (PANI) to overcome traditional energy density limitations in supercapacitors.
• It achieves ultrahigh energy and power densities, maintaining stable performance over 100,000 charge-discharge cycles and under high-voltage conditions.
• The device's mechanical flexibility allows it to be rolled or folded without performance loss, enabling integration into wearable electronics and other adaptable technologies.
• Researchers have demonstrated cost-effective production methods by leveraging PANI, a low-cost conductive polymer, paving the way for mass production.
• Potential applications include electric vehicles, drones, and robots, with the technology offering fast charging, improved range, and enhanced sustainability for energy storage systems.
