SnSe2@C储钠负极材料的合成及电化学性能研究
Synthesis and Electrochemical Research of Sodium Storage Anode SnSe2@C
摘要
Abstract
Tin selenide(SnSe2)is a very promising negative electrode material for sodium ion batteries,which has advantages such as high theoretical specific capacity,wide range of raw materials,and low cost.However,it is also limited by the structural damage caused by volume expansion during charging and discharging processes.A research is conducted on the successful synthesis of carbon coated tin selenide(SnSe2@C)through high-temperature annealing.Carbon coating improves the conductivity and stability of the material as sodium-ion battery anode,making SnSe2@C has high specific capacity(549.0 mAh·g-1 at 1.0 A·g-1)and excellent rate performance(427.7 mAh·g-1 at 5.0 A·g-1).关键词
