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

In this work, peony-like structured MoS 2 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 2 can maintain 157.7 mA h g -1 at 0.1 A g -1 after 80 cycles and 77.8 mA h g -1 at 1 A g -1 after 750 cycles.
