Abstract
This work introduces a facile solution method for preparation of porous Li4Ti5O12 (LTO) thin film electrode for lithium-ion batteries (LIBs). The porous LTO films were prepared by magnetron sputtering deposition using cubic spinel LTO powder target as a sputtering source. The microstructure and morphology of the LTO thin films annealed in air (LTO-air) was porous structured thin film. The LTO-air thin film electrode showed the excellent electrochemical performance. The capacity of LTO-air up to 81 μAh cm−2μm was at 10 μA cm−2, and capacity retention was 99% after 100 cycles at 10 μA cm−2. The porous structure features of thin film likely contributed to the good electrochemical performance of the LTO-air thin film. This research suggests that LTO thin films have the potential for the high energy storage electrode material for LIBs.
