▎ 摘 要
Zinc-based bimetal oxides have received considerable attention as anode for lithium-ion batteries (LIBs). A one-pot self-assembly hydrothermal method is developed for the fabrication of 3D hierarchical structure aerogels from zinc stannate (ZnSnO3) and reduced graphene oxide (rGO). 3D interconnected porous structure with ZnSnO3 hexagon nanoplates uniformly dispersed on graphene sheets has been constructed successfully, in which the crystalline hexagon nanoplates ZnSnO3 are firstly used to prepare ZnSnO3-based anode materials for LIBs. The as-prepared ZnSnO3 nanoplates/reduced graphene oxide aerogels (ZnSnO3-rGAs) electrode demonstrates an excellent reversible capacity (780 mAh g(-1)) after 200 cycles at a certain current density (100 mA g(-1)) and still delivers a specific capacity of 460 mAh g(-1) even at 1000 mA g(-1). The superior performance of lithium storage is attributed to the 3D porous hierarchical structure and the synergistic effects of uniform hexagon nanoplates ZnSnO3 and rGO sheets.
