Two-Dimensional Films Based on Graphene/Li₄Ti₅O₁₂ and Carbon Nanotube/Li₄Ti₅O₁₂ Nanocomposites as a Prospective Material for Lithium-Ion Batteries: Insight from Ab Initio Modeling.

ABSTRACT: The combination of spinel Li₄Ti₅O₁₂ (LTO) with carbon nanostructures, such as graphene (G) and carbon nanotubes (CNTs), provides all of the required properties for modern chemical power sources such as Li-ion batteries (LIBs) and supercapacitors (SCs). G/LTO and CNT/LTO composites demonstrate a superior reversible capacity, cycling stability, and good rate performances. In this paper, an ab initio attempt to estimate the electronic and capacitive properties of such composites was made for the first time. It was found that the interaction between LTO particles and CNTs was higher than that with graphene due to the larger amount of transfer charge. Increasing the graphene concentration raised the Fermi level and enhanced the conductive properties of G/LTO com
