摘要：

A two-step coating approach followed by thermal treatment and etching is used to construct a double hollow nanostructure of Zn2SnO4/SnO2 encased by N-doped carbon for LIBs. Thanks to the unique structure, the sample can deliver ultra-high discharge capacities of 1085.2 and 469.3 mA h g-1 at 0.1 and 5.0 A g-1. The reversible capacity can be maintained at 625 mA h g-1 after 900 cycles at current density of 1.0 A g-1. Furthermore, a full -cell is tested, and displays superior electrochemical performance. The boosted properties demonstrate that the strategy of structure-engineering offers a vast promise to promote energy storage applications.
