Ion conduction refers to a conductive process consisting of the directional motion of ions driven by an electric field, which is one of the most important issues for further improvement of batteries in the current and foreseeable future. In order to better understand the conduction phenomena in alkali metal‐ion (Li⁺/Na⁺/K⁺) batteries (AMIBs) and achieve technological breakthroughs, the recent studies on the ion diffusion of electrode materials and the ion conduction of electrolytes for AMIBs are investigated. Three aspects of the factors that affecting ion conduction in AMIBs are mainly listed: (i) crystal structure related high ion conduction in crystalline materials. (ii) tuning the lattice volume and interface by doping and compounding. (iii) improvement in experimental synthesis and modification methods. Through this review, we hope to facilitate more efficient and targeted research to improve ion conduction in AMIBs.

碱金属离子电池中提高离子传导性的策略的最新研究

离子传导是指由电场驱动的离子的定向运动组成的传导过程，这是当前和可预见的未来电池进一步改进的最重要问题之一。为了更好地理解碱金属离子（Li ⁺ / Na ⁺ / K ⁺电池（AMIBs）并取得了技术突破，最近对AMIBs电极材料的离子扩散和电解质的离子传导进行了研究。主要列出了影响AMIBs中离子传导的因素的三个方面：（i）与晶体结构有关的晶体材料中的高离子传导性。（ii）通过掺杂和复合来调整晶格的体积和界面。（iii）改进实验合成和修饰方法。通过这次审查，我们希望促进更有效，更有针对性的研究，以改善AMIBs中的离子传导。
