Conductive membranes of EVA filled with carbon black and carbon nanotubes for flexible energy-storage devices

Abstract

A novel class of flexible carbon black and carbon nanotube filled ethylene-vinyl acetate copolymers (ExByCz) were designed and fabricated as substrates for high-performance flexible supercapacitors' electrodes. The electrodes that employed these substrates exhibited good rate capability, high specific capacitance (214.6 F g−1), high specific power density (10 950 W Kg−1) and high energy density (30.4 W h Kg−1).
