英文摘要	2D materials have attracted extensive attention in energy storage and conversion due to their excellent electrochemical performances. Herein, we report utilization of monolayer SnS2 sheets within SnS2/graphene multilayers for efficient lithium and sodium storage. SnS2/graphene multilayers are synthesized through a solution-phase direct assembly method by electrostatic interaction between monolayer SnS2 and PDDA (polydimethyl diallyl ammonium chloride)-graphene nanosheets. It has been shown that the SnS2/graphene multilayer electrode has a large pseudocapacity contribution for enhanced lithium and sodium storage. Typical batteries deliver a stable reversible capacity of similar to 160 mA h g(-1) at 2 A g(-1) after 2000 cycles for lithium and a stable reversible capacity of similar to 142 mA h g(-1) at 1 A g(-1) after 1000 cycles for sodium. The excellent electrochemical performances of SnS2/graphene multilayers are attributed to the synergistic effect between the monolayer SnS2 sheets and the PDDA-graphene nanosheets. The multilayer structure assembled by different monolayer nanosheets is promising for the further development of 2D materials for energy storage and conversion.
