Newborn 2D materials for flexible energy conversion and storage

新兴二维材料在柔性能源存储和转换中的应用（英文）

Newborn two-dimensional materials(NB2DMs) beyond graphene such as transition metal dichalcogenides(TMDs) exhibit excellent optoelectronic and mechanical properties as well as high theoretical specific capacity, which make them become the promising building blocks of flexible energy devices related to energy conversion and storage. Compared to graphene with zero band gap or traditional friable materials such as Si, these NB2 DMs are more suitable to construct flexible devices as active layers of optoelectronic devices or as active materials for batteries. The present review focuses on the recent advances in bendable energy devices based on NB2 DMs, including batteries, supercapacitors(SCs), solar cells, photodetectors and nanogenerators(NGs). The NB2 DMs pave a new way to construct next-generation flexible energy devices with improved performance and we believe that those devices will be seen in our daily life and change our lifestyle in the immediate future.
