Dual anode materials for lithium- and sodium-ion batteries

Currently, the application of new energy conversion and storage technologies is urgent in order to meet the increasing requirements for energy. Rechargeable batteries are universal devices, and among them, the use of lithium-ion batteries and sodium-ion batteries is particularly extensive, and they show great potential. Thus, it is necessary to find suitable anode materials that have the capability of playing a dual storage role in both lithium-ion batteries and sodium-ion batteries. This review summarizes and evaluates recent progress in the research on dual anode materials for lithium-ion batteries and sodium-ion batteries in detail. The morphologies, synthesis schemes, and electrochemical performances of these materials and future prospects in this field are also included. Currently, the application of new energy conversion and storage technologies is urgent in order to meet the increasing requirements for energy.
