Facile synthesis of sulfide Bi(13)S(18)I(2) as a promising anode material for a lithium-ion battery

A novel Bi(13)S(18)I(2) structure was synthesized using a facile one-pot hydrothermal method and further optimized as an anode material using graphene. The graphene/Bi(13)S(18)I(2) composite achieved a high discharge capacity with an initial value of 1126.5 mA h g(−1) and a high and stable discharge...

Sumario:A novel Bi(13)S(18)I(2) structure was synthesized using a facile one-pot hydrothermal method and further optimized as an anode material using graphene. The graphene/Bi(13)S(18)I(2) composite achieved a high discharge capacity with an initial value of 1126.5 mA h g(−1) and a high and stable discharge capacity of 287.1 mA h g(−1) after 500 cycles compared with pure Bi(13)S(18)I(2), which derives from the inhibited volume expansion and high electrical conductivity obtained from graphene. In situ XRD was performed to analyze the Li storage mechanism in depth. The results support the feasibility of the new ternary sulfide Bi(13)S(18)I(2) as a promising lithium ion battery.
