Abstract

CuInZnS-decorated graphene (CIZS@graphene) is prepared via a hydrothermal process and investigated as an anode material for lithium-ion batteries. CIZS@graphene exhibits an initial discharge capacity of 1623 mA.h g^-1 at 100 mA g^-1, and at a high rate of 2000 mA g^-1 its reversible capacity is steadily increased from 389 mA h g^-1 to 494 mA h g^-1 in 480 cycles, demonstrating promising stable cycling performance at high rates. Electrochemical impedance spectroscopic studies show that charge-transfer resistances of CIZS@graphene reduces after cycling at high rates, justifying the excellent high-rate performance and stability of the CIZS@graphene anode.
