Introducing Rolled-Up Nanotechnology for Advanced Energy Storage Devices

摘要

Energy storage devices, acting as complementing units for renewable energy sources, play a key role in modern society, and they serve as the dominant power supply for most portable electronics. At the heart of the development of next-generation energy storage devices lies the exploration of intrinsic material properties, architectural design and fabrication methods. Rolled-up nanotechnology, a unique method to self-assemble nanomembranes into 3D structures using strain engineering, has advanced the development of energy storage devices with superior performance. In this review, the recent progress of employing rolled-up nanotechnology is focused to design rational electrodes for Li-ion (LIBs) and Li-O-2 batteries. A comprehensive summary of the fabrication and application of diverse rolled-up structures in these electrochemical energy storage devices is provided. Apart from this, the great potential of this approach is also highlighted for scalable miniaturized microdevice fabrication, including micro-LIBs, microsupercapacitors, and microscale ultracompact capacitors. These devices offer a promising platform not only for electrochemical microprobes, but also for lab-on-a-chip applications. Finally, prospects and challenges of employing rolled-up nanotechnology for future research and development in the broad field of energy storage systems are discussed.
