Li4Ti5O12 (LTO) has drawn great attention due to its safety and stability in lithium ion batteries (LIBs). However, high potential plateau at 1.5 V vs. Li reduces the cell voltage, leading to a limited use of LTO. Dual ion batteries (DIBs) can achieve high working voltage due to high intercalation potential of cathode. Herein, we propose a DIB configuration in which LTO is used as anode and the working voltage was 3.5 V. This DIB achieves a maximum specific energy of 140 Wh/kg at a specific power of 35 W/kg, and the specific power of 2933 W/kg can be obtained with a remaining specific energy of 11 Wh/kg. Traditional LIB material shows greatly improved properties in the DIB configuration. Thus, reversing its disadvantage leads to upgraded performance of batteries. Our configuration has also widened the horizon of materials for DIBs.
