摘要

Three-dimensional Prussian blue (PB) nanostructures was obtained via a one-step hydrothermal method. Subsequently, two-dimensional tin disulfide (SnS ) nanosheets were grown onto PB through a facile hydrothermal synthesis. The as prepared SnS /PB is further employed as the anode of sodium ion batteries (SIBs). SnS /PB nanoarchitecture delivers a specific capacity of 725.7 mAh∙g at 50 mA∙g . When put through more than 200 cycles, it achieved a stable cycling capacity of 400 mAh∙g at 200 mA∙g . The stable Na storage properties of SnS /PB was attributed to the synergistic effect among the conductive PB carbon, used as the template in this work. These results obtained potentially paves the way for the development of excellent electrochemical performance with stable performance of SIBs.
