英文摘要

Although Ti 3 C 2 MXene sheets have attracted extensive attention in lithium-ion storage techniques, their restacking makes against and even hinders the Li ions diffusion within them, thereby decreasing the capacity as well as rate performance of conventional MXene anode. Here, for the first time, we roll up the Ti 3 C 2 T x sheets into scrolls with unclosed topological structure and the interlayer galleries to alleviate the restacking problem. Thus, Ti 3 C 2 T x scrolls as anode materials in lithium-ion batteries (LIBs) have higher capacity and better rate performance than Ti 3 C 2 T x sheets. On the bases of these, high-capacity silicon nanoparticles are added during the rolling process to in-situ produce Ti 3 C 2 T x /Si composite scrolls. The addition of 10% silicon nanoparticles shows the best overall improvement among capacity, rate capability and cyclic stability for Ti 3 C 2 T x scrolls.
