Abstract

Fe₂O₃ thin films are important for the fabrication of rechargeable lithium microbatteries. Thin films of Fe₂O₃ were prepared by the electrostatic spray deposition (ESD) technique by using iron chloride as the precursor. The thin film electrodes, without inert additives such as polymer binder and conducting material, can deliver a first discharge capacity of 912 mA h g⁻¹ and retain a discharge capacity of 537 mA h g⁻¹ at a current density of 200 mA g⁻¹ to the 100th cycle. The coulombic efficiency of the Fe₂O₃ thin-film electrode was over 96% after several cycles.
