This study is investigated the blending polymer electrolyte thin films based on PVA/PECH through varied the blending ratios of PVA:PECH. The ionic conductivity of the alkaline PVA/PECH blending polymer electrolyte thin film was over 10¯² S/cm after absorbing KOH electrolyte. The solid-state Zn-air battery comprised of Zn gel anode and the air cathode was assembled and tested with the capacity of 1476 mAh. The utilization percent of battery was found over 90% at C/10 discharge rate.
