Aluminum is considered as one of the most promising anode materials for the next generation batteries, in this paper, we used conductive Ti₃O₅ shell coating nano-Al powder to prepare the core-shell structure material of Al@Ti₃O₅, and used it as an anode, accompanied by of MCMB as the cathode, to assemble the Al@Ti₃O₅-MCMB Dual-ion battery (DIB). The discharge platform of the Al@Ti₃O₅-MCMB DIB is up to 4.5V, and the discharge capacity can reach 130.6mAhg^_-1, specific energy density 278.8Whkg^_-1 at a current rate of 0.5C (the current rate is based on the theoretical specific capacity of graphite and 1C corresponding to 372 mAhg^_-1). The Al@Ti₃O₅-MCMB DIB shows excellent cyclic stability, and the capacity remains at around 110mAhg^_-1 in the process of circulating 1000 times under the current rate of 5C, with a capacity retention rate of 92.9% after circulation.
