  • Silicon anodes are considered to have great prospects, but many of their defects still need to be improved. To prepare hybrid materials based on porous carbon is one of the effective ways to alleviate the adverse impact resulting from the volume change and the inferior electronic conductivity of silicon electrode. Herein, a chain-like carbon cluster structure is prepared, in which MOF-derived porous carbon acts as a shell structure to integrally encapsulate Si nanoparticles, and CNTs play a role in connecting carbon shells. Based on the exclusive structure, the carbon shell can cushion the volume expansion more effectively and CNTs can improve overall stability and conductivity. The resulted composite reveals excellent rate capacity and enhanced cycling stability, which in particular achieve a capacity of 732 mAh g-1 at 2 A g-1 and shows a reservation rate of 72.3% after cycling 100 times at 1 A g-1.
