文摘

Hollow fiber electrodes based on graphene/conducting polymer are developed by J. Cheng, B. Wang, H. Peng, and co-workers to fabricate novel and high-performance fiber-shaped supercapacitors. As described on page 3646, the hollow composite fiber supercapacitors have an ultra-high specific capacitance of 304.5 mF cm⁻² and an ultra-high energy density of 27.1 μW h cm⁻² at a power density of 66.5 μW cm⁻². These mechanical and electrochemical properties make the fiber supercapacitors a promising material for next-generation wearable electronics.
