Fabrication of high-performance flexible alkaline batteries by implementing multiwalled carbon nanotubes and copolymer separator

Abstract

A flexible alkaline battery with multiwalled carbon nanotube (MWCNT) enhanced composite electrodes and polyvinyl alcohol (PVA)-poly (acrylic acid) (PAA) copolymer separator has been developed. Purified MWCNTs appear to be the most effective conductive additive, while the flexible copolymer separator not only enhances flexibility but also serves as electrolyte storage. © 2013 WILEY-VCH Verlag GmbH & Co.
