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.
