这篇文章回顾了离子材料中原子输运的知识现状，这是近四十年来EURODIM会议系列的主要主题。该主题的早期历史简要回顾了二战后早期发生的重要发展。这项工作主要是基于对单晶形式的相对简单的二元离子系统的研究，为目前的许多知识奠定了基础。概述了最近关于快离子导体的工作，其中材料通常更复杂，目的是生产良好的离子导体，用于电池和燃料电池中的电解质膜。这包括计算机模拟技术的发展，现在几乎是任何离子运输调查的重要组成部分。最后，一个简短的总结是在纳米晶体离子材料（nanoionics）的运输已被报道增强离子传导与显着改善设备的潜力。（© 2007 WILEY‐VCH Verlag GmbH & Co.

This contribution reviews the current state of knowledge of atomic transport in ionic materials, a dominant theme of the EURODIM Conference series for nearly four decades. The early history of the subject is briefly reviewed followed by the important developments that occurred in the early post‐WWII period. That work was mainly based on studies of relatively simple binary ionic systems in the form of single crystals and laid the foundation for much of the current knowledge. An overview is given of more recent work on fast‐ion conductors where the materials are generally more complex and the aim is to produce good ionic conductors for applications as electrolyte membranes in batteries and fuel cells. This includes the development of computer simulation techniques that are now an almost essential part of any investigation of ionic transport. Finally, a brief summary is given of transport in nanocrystalline ionic materials (nanoionics) where enhanced ionic conduction has been reported with the potential for significantly improved devices.
