Ultrathin ReS2 nanosheets growing on ordered microporous carbon for high capacity lithium ion batteries

To improve the Li storage capability of rhenium disulfide (ReS2) as anode materials for lithium ion batteries (LIBs), the ReS2@CMK-3 composites were designed and prepared by using CMK-3 as a nano-reactor. The ReS2@CMK-3 composites possessed a special nanosheets-on-channel architecture that the ultrathin ReS2 nanosheets grown on the channel of CMK-3. Owing to the large surface area, ordered mesoporous structure and excellent electronic conductivity, the ReS2@CMK-3 composites exhibited larger discharge capacity, superior cycling performance and higher rate performance compared with pristine ReS2 when they were applied as anode materials for LIBs. As a result, the ReS2@CMK-3 composites delivered a reversible capacity of 620 mAh g(-1) after 200 cycles at 0.5 A g(-1), indicating their potential as promising anode materials for LIBs.
