As one of the main anode materials for sodium ion batteries, SnS2 has great advantages but is also accompanied by obvious flaws. Using GO is not enough to make up for its huge flaws. This article uses a ternary complex that combines SnS2 with GO and Ag ions, this is the first time that Ag+ has been used to improve the anode materials for sodium ion batteries. Ag+ plays a role in increasing the binding capacity of sodium ions and the anode material, it also improves the spacing of graphene sheets to relieve the serious volume expansion of SnS2. After 50 cycles, the discharge specific capacity was increased from 217.1 mAh/g to 385.2 mAh/g, the capacity retention rate can be increased by 19.11%.
