Lead‐free hybrid and inorganic perovskites (A 2 CuBr 4 ; A=CH 3 NH 3 or Cs, 2 D or3 D) are synthesized by a room‐temperature solid‐state reaction route and examined as anode materials in Li‐ion batteries. A remarkably high reversible capacity of 630 mAh g −1 is realized in the 2 D hybrid perovskite at 100 mA g −1 at the end of 140 cycles. A full cell with this anode is also tested and shows impressive cycling stability. A good reversible capacity of 420 mAh g −1 with excellent stability tested up to 1400 cycles is also obtained for the 3 D perovskites. Pb‐free hybrid/inorganic halide perovskites can thus be used as viable anode materials for battery applications.
