Zusammenfassung:•3D porous Li4Ti5O12@carbon was investigated as anode in dual-ion batteries.•The Li+ diffusion rate of Li4Ti5O12@carbon was greatly enhanced.•Li4Ti5O12@carbon anode demonstrates high cycling stability. Dual-ion battery (DIB) paring lithium titanate (LTO) anode with graphite cathode is attractive for energy storage applications owing to its merits of environmental friendly, excellent cyclic stability, and good safety. However, the specific capacity of the LTO-DIB is still relatively low (
