摘要

•ZSF@C is fabricated via hydrothermal method with subsequent dopamine coating and annealing.•ZSF hierarchical structure composed of nanoflakes shortens the Li+/Na+ diffusion pathways.•Amorphous carbon layer enhances the electronic conductivity, buffers the volume variation, and keeps the structure integrity.•ZSF@C composite exhibits excellent rate and cycling performance for LIBs and SIBs.
