Symposium EL18-Fundamentals of Mixed Ionic-Electronic Conductors

Mixed ionic-electronic conductors, also known as mixed conductors, are an increasingly important category of materials with applications in energy storage, electrochromic displays, bioelectronics, sensors, electrocatalysis, neuromorphic devices, and actuators. Mixed conductors exhibit both ion and electron/hole conductivity, and ionic-electronic coupling (i.e., capacitance), allowing them to effectively transduce ionic signals to electronic ones, and vice versa. In recent years, new mixed conductors have been developed beyond the traditional metals oxides and phosphates to include (semi)conducting polymers, radical polymers, perovskites, and hybrid organic-inorganic materials, enabling improved performance and new functionalities. Despite these advances, challenges remain in characterizing and modeling the dynamic relationship among electronic transport, ionic transport, and material structure during device operation. This symposium will focus on the synthesis, characterization, and modeling of these emerging materials, with an emphasis on their fundamental understanding, existing challenges, and future directions. In particular, new material designs and synthetic approaches, structure-property relationships, mechanical properties, device physics and engineering, electrochemical transistors, in-situ and in-operando characterization, materials and device stability, theory, modeling, and molecular dynamics simulations will be covered. This symposium will provide a unique opportunity to bring together experts in organic, inorganic, and hybrid materials to discuss the fundamentals of mixed ionic-electronic conductors.

  • Design and synthesis of new materials
  • Organic (semi)conductors
