The fabrication of flexible nickel-zinc battery using a facile mixing of electroactive components for electrode preparation is presented. Polytetrafluoroethylene (PTFE) was found to be an effective binding additive by reducing concentration polarization, providing chemical/physical stability and enhancing flexibility. The zinc electrode containing PTFE maintained its original porous morphology even after hundreds of cycles while polymers such as PEO showed morphology change. Each component, as well as the assembled flexible cells, showed desired flexibility and stability even under bending conditions.
