LaTi₂₁O₃₈/CuLaO₂/CoO Nanorods as High‐Performance Anode Materials for Lithium‐Ion Batteries

Abstract

Ti−Co−Cu composites as anode for lithium‐ion batteries are outstanding materials to obtain high specific capacity and cycle stability. In this work, LaTi21O38/CuLaO2/CoO composite materials (LTCLC) were designed by a simple electrospinning method. Impressively, the addition of La elements to LTCLC nanorods with porous structures improved the electrochemical performance of CuO/CoTiO3/TiO2 (TCCT) as an anode for Li‐ion batteries. The LTCLC materials have the capacity of 129.8 mAh g−1 at high current density of 1000 mA g−1 and the coulombic efficiency can be maintained at 98.22 % after 800 cycles, indicating the excellent cycling stability. The excellent electrochemical performance could be assigned to the credible one dimensional nanostructure and synergistic effect of lanthanum elements. The composites may hold great applications as high performance anode materials for LIBs.
