Recent advances in the use of organic-inorganic hybrid perovskites have been investigated in a variety of ap-plications, such as solar cells, photodetectors, light-emitting devices, and lasers, because of their outstanding semiconductor properties. Furthermore, the perovskite structure can host extrinsic elements, making it a promising candidate for battery applications. Previous studies have shown that organic-inorganic hybrid pe-rovskites can be suitable anode materials for both lithium-and sodium-ion batteries. However, multivalent rechargeable batteries with perovskite materials have not yet been realized. Herein, we studied the electro-chemical performance of three-dimensional (CH3NH3PbI3 (MAPbI3) and long-chain alkylammonium (C4H9NH3)2(CH3NH3)3Pb4I13 ((iBA)2(MA)3Pb4I13) thin films as electrode materials for rechargeable Al-ion bat-teries. Our results showed that (iBA)2(MA)3Pb4I13 presented a specific capacity of 257 mAh g-1 at a current density of 0.1 A g-1 and delivered 108 mAh g-1 after 250 cycles at a current density of 0.3 A g-1 with a retention of as high as 91 %, demonstrating a crucial role of isobutyl amine (C4H9NH3) due to the unique hydrogen-bonding interaction of isobutyl amine that hinders the shuttle effect of polyiodide. The results open a new di-rection for the use of organic-inorganic hybrid perovskites for new secondary aluminum ion batteries.
