Defect engineering of molybdenum disulfide nanosheets boosting super Zn 2+ storage from polyaniline intercalation

In this work, peony-like structured MoS with intercalation of polyaniline and crystal defects was prepared by a simple hydrothermal method. The defect-rich structure and broad interlayer distance can effectively provide vast ion transport paths to enhance the ion diffusion rate. PA-MoS can maintain 157.7 mA h g at 0.1 A g after 80 cycles and 77.8 mA h g at 1 A g after 750 cycles.
