With the rapid development of portable electronic devices, hybrid vehicles, electric vehicles, and space technology, secondary batteries have put forward higher requirements in terms of specific capacity, cycle life, and safety. Improving and improving the electrochemical performance of batteries can start from the aspects of electrode materials.In recent years, lithium titanate (Li4Ti5O12) has received extensive attention as a safe and long-life anode material. Li4Ti5O12 is a white substance, non-conductive, and can exist stably in the air. Li4Ti5O12 has a spinel structure with a space group of Fd3m, in which O2− ions form the FCC lattice, located at the position of 32e, part of Li+ is located in the tetrahedral gap of 8a, and part of Li+ and Ti4+ are located in the octahedral gap of 16d. Its structural formula can be written as [Li]8a[Li1/3Ti5/3]16d[O4]32e, and the lattice constant is 0.8364 mm.Thinpack improved LTO batteries excelled on buses
