Solvothermal synthesis of flower-like Cu2ZnSnS4 nanostructures and their application as anode materials for lithium-ion batteries

► Flower-like Cu2ZnSnS4 nanostructures were synthesized by solvothermal method. ► The CZTS nanostructures could be used as anode materials for lithium-ion batteries. ► The flower-like CZTS electrodes exhibited high stability. ► The performance of CZTS can be ascribed to their flower-like nanostructures.
