Oxygen and cation diffusion processes in oxygen ion conductors [PDF]

Diffusion Fundamentals, 2007
We discuss oxygen and cation diffusion processes in oxygen ion conductors. While the high oxygen diffusivity determines the proper oxygen ion conductivity, slow cation diffusion processes are important for sintering and degradation processes. In the first part of the paper we discuss an analytical model for the ionic conductivity of a strongly acceptor

Cation Demixing in an Oxygen Ion Conductor Exposed to an Oxygen Potential Gradient

ECS Proceedings Volumes, 1999
This paper gives a formal analysis of cation demixing in an oxygen ion conductor AO2(+B2O3) which is exposed to an oxygen potential gradient and an electronic short-circuit (SOFC conditions).

EISCAT/CRRES observations: Nightside ionospheric ion outflow and oxygen-rich substorm injections [PDF]

, 1996
We present combined observations made near midnight by the EISCAT radar, all-sky cameras and the combined released and radiation efects satellite (CRRES) shortly before and during a substorm.

Preparation of Composite Single‐Ion Conductor Membrane and Its Application in Lithium–Oxygen Battery

Advanced Energy & Sustainability Research, 2023
Redox mediators (RMs) are reported to effectually encourage the inactive decomposition of discharge products in lithium–oxygen batteries (LOBs); however, oxidized RMs and other injurious species still attack the Li anodes.

Oxygen ion conductors

Materials Today, 2003
Abstract Ionic conductors have always provided a fascinating interdisciplinary field of study ever since their discovery by Faraday at the Royal Institution in London over 200 years ago. More recently, and particularly in the past decade, the pace of research has been rapid, driven by the requirements for new clean energy sources, sensors, and high ...

Environmentally regulated intrinsic oxygen-ion transport for oxide-ion conductors

Journal of Materiomics, 2023
Oxide-ion conductors have been widely used as catalytic, conductive, detecting and other materials under oxidizing, reducing, inert, mixed environments and the like. However, so far the evaluation of their oxygen-ion transport (such as oxide-ion conductivity and oxygen permeability) either is extrinsic or is limited only in oxidizing or inert ...
