摘要：

Aluminum batteries (ABs) are a promising alternative to lithium-ion batteries (LIBs) in the future. The development of aluminum batteries (ABs) is closely related to their cathode material. In this paper, we successfully designed and prepared a nanorod structure Sb2Se3@PPy as cathode material for ABs. It exhibits a high reversible capacity of 302 mAh/g at 0.2 A/g, and the capacity is maintained at about 210 mAh/g after 50 cycles. In addition, the electrochemical reaction mechanism and kinetic process of Sb2Se3@PPy were studied. The results showed that the PPy coating layer reduced the volume change of Sb2Se3, prevented irreversible deformation, enhanced the structural stability and electronic conductivity.
