Tin phosphide (Sn₄P₃) as the anode material for lithium?ion batteries exhibits high theoretical specific capacity (1.255×10³ mA ? h/g). However, the huge volume expansion and particle agglomeration during the charging and discharging processes lead to serious capacity attenuation. The carbon?coated Sn₄P₃?graphene composite (Sn₄P_3?G@C) was successfully prepared by using graphene as the framework and amorphous carbon material as the coating layer. Sn₄P₃?G@C composite shows a high discharge specific capacity of 0.521×10^-3 mA ? h/g after 70 cycles at 0.05 A/g, and the discharge specific capacity of 0.433×10^-3 mA ? h/g can be maintained after 150 cycles at 0.10 A/g. After 300 cycles at 0.50 A/g, the reversible specific capacity of 0.330×10^-3 mA ? h/g can be exhibited. The co?existence of sheet graphene and carbon coating can not only stabilize the structure of Sn₄P₃ and improve the electrical conductivity of the material, but also effectively alleviate the problem of volume expansion and prevent the agglomeration between particles. Sn₄P₃?G@C shows good lithium storage performance.
