Sulfur vacancy and heterojunction synergistic effects inBi2S3/ZnS@C composite promote the fast diffusion dynamics of electrons and ions in Li-/Na-ion batteries

Addressing the bottleneck of capacity decay in Bi2S3 anodes caused by intrinsic low conductivity and structural instability from Bi-S bond reorganization is a huge challenge. Herein, a synergistic heterojunction-vacancy strategy...
