摘　　要：The rising.demand for portable and environmentally sustainableenergyfor use in the electronic/electrical equipment,automobile,and so on has resulted in an ever-increasing development in the rechargeable metal-ion-battery technologies.The anode is a crucial component of the battery system,influencing both the cost and overall performance of the batteries.To optimize the electrochemical properties of anode materials,constructing the dual-phase structure has been identified as an effective strategy.The mutual buffering between phases helps alleviate dramatic volume changes,while the abundant interfaces increase active sites and enhance the ion transport.In this review,the research and development of main anode materials with dual-phase configurations in Li/Mg ion batteries are summarized and discussed.The fabrication methods,regulation strategy,electrochemical performance,as well as enhancement mechanisms of dual-phase Li_(4)Ti_(5)O_(12)-TiO_(2) composites,TiO_(2)-based composites,alloy-type materials,and other types of dual-phase anodes are reviewed and compared in detail.Moreover,some perspectives about the future progress of dual-phase anode materials for metal-ion batteries are proposed.
