文摘

In this paper, we present the development of flexible zinc–air battery. Multiwalled carbon nanotubes (MWCNTs) were added into electrodes to improve their performance. It was found that MWCNTs were effective conductive additive in anode as they bridged the zinc particles. Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) was applied as a co-binder to enhance both the conductivity and flexibility. A poly (acrylic acid) (PAA) and polyvinyl alcohol (PVA) coated paper separator was used to enhance the battery performance where the PVP–PAA layer facilitated electrolyte storage. The batteries remained functional under bending conditions and after bending. Multiple design optimizations were also carried out for storage and performance purposes.
