摘要
It is believed that the construction of a well-hybridized and nanoscale SnS 2 -rGO interconnection would make Li + diffusion distance shorter, cycle performance stable and high-rate property remarkable application in the LIBs anodes. Here, a novel SnS 2 /rGO aerogel with ultrathin SnS 2 nanosheets, well-hybridized networks, and desirable covalent-bonded interconnection was successfully prepared by a modified one-step hydrothermal method. The aerogels were used for anode of lithium-ion batteries (LIB), and exhibited a remarkable electrochemical performance, including an ultra-high initial specific capacity (1682 mAh g −1 ), excellent rate performance (474 mAh g −1 at the rate of 10 A g −1 ), and perfect cycle stability (1388.4 mAh g −1 after 100 cycles at 0.1 A g −1 ), superior to those of previous reports. It is obvious that the aerogel’s well-hybridized and covalent-bonded networks, super stable and intact structure, and improved electron conductivity would play a very important role during charging/discharging of the improved Li + transportation. Therefore, the SnS 2 /rGO aerogel materials created by us would be a very promising candidate for future advanced lithium-storage-type power sources.
