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.
