High Lithium Storage Performance of Co Ion-Doped Li₄Ti₅O₁₂ Induced by Fast Charge Transport.

ABSTRACT: In this study, Co₃O₄-doped Li₄Ti₅O₁₂ (LTO) composite was designed and synthesized by the hydrothermal reduction method and metal doping modification method. The microstructure and electrochemical performance of the Co₃O₄-doped Li₄Ti₅O₁₂ composite were characterized by XRD, SEM, TEM, electrochemical impedance spectroscopy, and galvanostatic tests. The results showed that Li₄Ti₅O₁₂ particles attached to lamellar Co₃O₄ constituted a heterostructure and Co ion doped into Li₄Ti₅O₁₂ lattice. This Co ion-doped microstructure improved the charge transportability of Li₄Ti₅O_12</
