Enhanced Li+ storage through highly hybridized networks of self-assembled SnS2/rGO aerogels

Abstract It is believed that the construction of a well-hybridized and nanoscale SnS2-rGO interconnection would make Li+ diffusion distance shorter, cycle performance stable and high-rate property remarkable application in the LIBs anodes. Here, a novel SnS2/rGO aerogel with ultrathin SnS2 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 SnS2/rGO aerogel materials created by us would be a very promising candidate for future advanced lithium-storage-type power sources.
