A facile one-step solvothermal method was used to synthesize SnS/SnO2/C nanocluster particles, which showed high discharge capacity as anode materials for lithium-ion batteries at a current density of 100 mA g(-1).
A facile one-step solvothermal method to synthesize SnS/SnO2/C nanocluster particles has been reported. The nanocluster particles are derived from SnS2/C composite materials by adjusting pyrolysis temperature at 600 degrees C within 6 h under N-2 atmosphere. When assessed as anode materials for lithium-ion batteries (LIBs), SnS/SnO2/C nanocluster particles can deliver a high initial discharge capacity of 1978 mA h g(-1) and maintain high discharge capacity of 638 mA h g(-1) after 50 cycles at a current density of 100 mA g(-1), which is better than other pyrolysis products derived from SnS2/C materials. This work indicates that SnS/SnO2/C nanocluster particles may be a promising anode material for lithium-ion batteries and provides a simple method to construct ternary composite materials for energy storage.
