Enhanced Electrochemical Properties of d-Ti₃C₂T_x Anode by h-BN Addition for Lithium-Ion Rechargeable Battery

Abstract

For lithium-ion batteries (LIBs) with high energy density, it is critical to develop reliable and high-capacity anode materials. In this work, d-Ti3C2Tx/h-BN hybrid layered nanocomposites with uniform distribution are synthesized using a simple liquid phase blending method and investigated as an anode material for LIBs. The results reveal that the uniformly dispersed h-BN anchored on the d-Ti3C2Tx nanosheets can effectively prevent the d-Ti3C2Tx nanosheets from restacking during charging and discharging processes, as well as improve the electronic conductivity. The studies show that the electrochemical performance, such as the capacity and cyclic stability, of d-Ti3C2Tx/h-BN electrode is better than that of pure d-Ti3C2Tx materials.
