Aluminum-ion batteries have become a promising energy storage device due to their low cost, large volume specific capacity, and environmental friendliness. Due to the poor reversibility and conductivity of traditional electrode materials, the development of aluminum-ion batteries has been greatly hindered. In this paper, a new stable WS2/WO3 cathode for aluminum-ion batteries was prepared by the coprecipitation method. The introduction of the WS2/WO3 heterojunction greatly enhances the electron transfer rate between the material interfaces, and...
