▎ 摘　　要

SnS2 has been considered as one of the most potential anode materials for lithium storage due to its high theoretical capacity. However, the SnS2-based electrodes still suffer from unsatisfied electrochemical lithium-storage performance due to the intrinsic poor conductivity, large volume change during cycles, and great irreversibility of the initial conversion reactions. Herein, SnS2 quantum dots (QDs) are uniform fixed in S-doped reduced graphene oxide (rGO) nanosheets or nanoscrolls by a simple green one-step hydrothermal method, which deliver superior lithium-storage performance, such as a high initial reversible capacity of 1151 mA h g(-1) at a current density of 200 mA g(-1), high capacity retention of 87.7% after 300 cycles at 500 mA g(-1), and superior rate capacity of 314 mA h g(-1) at 5000 mA g(-1).
