Nanoionics is known as unique phenomena and properties connected with fast ion transport in all-solid-state nanoscale systems, especially in inorganic materials. We first revealed similar fast ion transport in organic polymer nanofibers fabricated by electrospinning and named this phenomenon “Organic Nanoionics” [1]. First, I will present such unique proton, anion, and lithium ion transport properties in the electrospun polymer nanofibers [2,3]. Then, I will share our work on polymer electrolyte membranes for fuel cells and secondary batteries [4-6]. The ion conductive polymer nanofiber composite electrolyte membranes showed improved electrolyte characteristics and fuel cell/battery performances by utilizing fast ion transport properties based on organic nanoionics. Finally, our recent work on hydrogen production by anion exchange membrane water electrolysis will be also presented [7].
