Abstract

In this work, a P–Sn@G composite is synthesized using a direct high-energy ball milling (HEBM) method with P, Sn, and expanded graphite (EG). The in situ formed few layered graphene (FLG) prevents the formation of Sn₄P₃ and establishes strong Sn–C and P–C co-bonding in the resultant P–Sn@G composite. Excellent lithium storage is also revealed due to the key effect of FLG to benefit the electronic transfer and buffer expansion stress of the electrode from Sn and P.
