In recent years, smart wearable electronic products have started to enter our daily life, and also greatly stimulated the researchers’ interest in flexible energy. The emerging two-dimensional materials represented by transition metal disulfide compounds show excellent Optical and mechanical properties, high theoretical specific capacity and other properties, making it flexible energy storage and conversion in the field of concern.Compared to the zero bandgap and low specific capacity of graphene or silicon and other traditional materials, these emerging two Dimensional materials have good application prospects in the construction of flexible optoelectronic devices and secondary batteries.This paper reviews the breakthrough of new two-dimensional materials in flexible energy applications such as secondary batteries, supercapacitors, solar cells, photodetectors and nano-generators Although there are still many problems in this emerging field, it is expected to be gradually solved in the near future through structure and material design and optimization.We believe that the application of these emerging two-dimensional materials will significantly improve the performance of flexible energy devices, And to promote the popularity of wearable electronics in our everyday lives.
