摘要

A two-dimensional layered Ti3C2/carbon nanotubes (CNTs) hybrid thin film was prepared. Owing to the excellent conductivity of the CNTs, this unique layered structure provides a rapid charge transfer path during the electrochemical reaction, as a lithium ion battery anode, which exhibits higher capacitance and better cycling stability (a reversible capacity of 428.1 mA h g(-1) at 0.5 degrees C after 300 cycles) compared with 96.2 mA h g(-1) of pure Ti3C2 nanosheets, as well as superior rate capability.
