摘要
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.
