抄録

Rechargeable aluminum batteries (RABs) are regarded as promising candidates for new-generation rechargeable batteries. However, due to the high charge density of Al3+, the modest cycling performance of RABs is difficult to improve, given the strong coulombic interaction between Al3+ and host materials. Heterostructure engineering is emerging as a promising strategy to further enhance the electrochemical performance of energy storage devices. Herein, heterostructured NiCo2Se4/NiCoS4 prepared via a two-step solvothermal treatment is reported as a new type of RAB cathode material. As expected, the heterostructured NiCo2Se4/NiCoS4 cathode delivers a discharged specific capacity of 112 mA h g−1 over 195 cycles. It is instructive to note that the operational mechanism of the RABs is the intercalation of Al3+ and the redox process of Co, Ni, and S elements.
