Large‐Area Polyimide/SWCNT Nanocable Cathode for Flexible Lithium‐Ion Batteries

A large-area flexible polymer electrode is fabricated using a new type of polyimide/single-walled carbon nanotube (SWCNT) nanocable composite. SWCNTs serve as the current collector and conductive network, and polyimide nanoparticles anchored on carbon nanotubes act as active materials. The electrode shows superior rate performance, good cycling stability, and high flexibility.
