摘要	Although Ti3C2 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 Ti3C2Tx sheets into scrolls with unclosed topological structure and the interlayer galleries to alleviate the restacking problem. Thus, Ti3C2Tx scrolls as anode materials in lithium-ion batteries (LIBs) have higher capacity and better rate performance than Ti3C2Tx sheets. On the bases of these, high-capacity silicon nanoparticles are added during the rolling process to in-situ produce Ti3C2Tx/Si composite scrolls. The addition of 10% silicon nanoparticles shows the best overall improvement among capacity, rate capability and cyclic stability for Ti3C2Tx scrolls. © 2019 Science Press and Dalian Institute of Chemical Physics, Chinese Academy of Sciences
