Research progress on Li_4Ti_5O_(12) as cathode material for lithium ion battery

As an anode material for lithium ion battery,the crystal form of Li4Ti5O12 does not change.So it is regarded as a“zero strain”material.The lithium ion battery using Li4Ti5Ol2 as cathode material has excellent cycle performance and plateau voltage.Because Li4Ti5Ol2 can avoid electrolytes decomposition and solid-electrolyte interphase(SEI) creation,the safety and reliability of the material is improved as compared with carbon electrode.The preparation process,state-of-the-art doping modification and the effect of structure on electrochemical properties of Li4Ti5Ol2 are introduced.
