Abstract:

Micro-energy storage devices are suitable for use in a range of potential applications, such as wearable electronics and micro-self-powered sensors, and also provide an ideal platform to explore the inner relationship among the electrode structure, electron/ion conductivity and electrochemical kinetics. Self-roll-up technology is an approach to rearrange automatically two-dimensional membrane materials because of residual stress. Compared with the conventional micro-nano fabrication technique, the self-roll-up technology realizes the ordered array of two-dimensional membranes, offering an effective and convenient way to fabricate microenergy storage devices. In this article, we review the recent important progresses of the self-roll-up technology for micro-energy storage devices, including the theory of the self-roll-up technology, and self-roll-up electrodes and their energy storage properties. Importantly, we highlight the practical applications of the self-roll-up technology for fabrication of single tubular micro lithium-ion batteries and capacitor arrays. Finally, future challenges and important opportunities of the self-roll-up technology for micro-energy storage devices are summarized and prospected.

Key words: Self-roll-up technology, Energy storage, Micro-device, Lithium-ion battery, Micro-capacitor
