Flowerlike Tin Diselenide Hexagonal Nanosheets for High-Performance Lithium-Ion Batteries

SnSe(2) nanosheet is a common anode for lithium-ion batteries (LIBs), but its severe agglomeration hinders its practical application. Herein, a three-dimensional (3D) SnSe(2) nanoflower (F-SnSe(2)) composed of non-stacking vertical upward hexagonal nanosheets was prepared through a colloidal method...

Descripción
Sumario:SnSe(2) nanosheet is a common anode for lithium-ion batteries (LIBs), but its severe agglomeration hinders its practical application. Herein, a three-dimensional (3D) SnSe(2) nanoflower (F-SnSe(2)) 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-SnSe(2) 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.
