Manabu Tanaka\, Tokyo Metropolitan University DTSTART:20240314T140000Z DTEND:20240314T150000Z UID:TALK212659@talks.cam.ac.uk CONTACT:Sharon Connor DESCRIPTION:Nanoionics is known as unique phenomena and properties connect ed with fast ion transport in all-solid-state nanoscale systems\, especial ly in inorganic materials. We first revealed similar fast ion transport in organic polymer nanofibers fabricated by electrospinning and named this p henomenon “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 electro lyte membranes for fuel cells and secondary batteries [4-6]. The ion condu ctive polymer nanofiber composite electrolyte membranes showed improved el ectrolyte characteristics and fuel cell/battery performances by utilizing fast ion transport properties based on organic nanoionics. Finally\, our r ecent work on hydrogen production by anion exchange membrane water electro lysis will be also presented [7].\n\n \n\n[1] M. Tanaka\, Polymer Journal\ , 48\, 51 (2016). [2] R.
