Abstract

SnSe₂ nanosheet is a common anode for lithium-ion batteries (LIBs), but its severe agglomeration hinders its practical application. Herein, a three-dimensional (3D) SnSe₂ nanoflower (F-SnSe₂) composed of non-stacking vertical upward hexagonal nanosheets was prepared through a colloidal method as an anode material for LIBs. Benefiting from the advantages of fast reaction-diffusion kinetics and buffering unavoidable volume variation during cycling, the F-SnSe₂ electrode displays remarkable specific capacity of 795 mAh g⁻¹ after 100 cycles at 100 mA g⁻¹ and superior rate performance (282 mAh g⁻¹ at 2,000 mA g⁻¹). This work provides an effective way to get non-stacking nanosheets in energy storage field.
