【摘要】：微型能源存儲器件在可穿戴電子產(chǎn)品、微型自驅(qū)動探測器等領(lǐng)域有重要的應(yīng)用前景,同時為研究儲能器件電極結(jié)構(gòu)、電子/離子傳導(dǎo)率以及電化學(xué)動力學(xué)之間的內(nèi)在聯(lián)系提供了理想的平臺。自卷曲技術(shù)是利用材料內(nèi)部存在的殘余應(yīng)力而實現(xiàn)二維薄膜材料自行彎曲的一種方法。相比于傳統(tǒng)微納制備工藝,這種方法可以在微米尺度下將二維薄膜電極材料有序卷曲排列,為微型儲能器件的制備提供了有效、便捷的途徑。本文介紹了近些年自卷曲技術(shù)在微型能源存儲器件上的重要進(jìn)展,其中包括材料自卷曲的原理、自卷曲電極及其儲能性質(zhì),并以此為基礎(chǔ),著重闡述了自卷曲技術(shù)制備單根管微型鋰離子電池和電容陣列的應(yīng)用實例�？偨Y(jié)并展望了自卷曲技術(shù)在微型儲能器件應(yīng)用上的未來挑戰(zhàn)和重要機遇。
[Abstract]:Micro energy storage devices have important application prospects in wearable electronic products, micro self drive detectors and so on. In order to study the electrode structure of energy storage devices, The internal relationship between electron / ion conductivity and electrochemical kinetics provides an ideal platform. Self-crimping technique is a method to realize the self-bending of two-dimensional thin film materials by using the residual stress inside the material. Compared with the traditional micro-nano fabrication process, this method can curl and arrange the two-dimensional thin film electrode materials in a micron scale, which provides an effective and convenient way for the fabrication of micro-energy storage devices. This paper introduces the important progress of self-crimping technology in micro-energy storage devices in recent years, including the principle of material self-crimp, self-crimp electrode and its energy storage properties. The application of self-curling technique to fabricating single-canal micro-lithium ion battery and capacitor array is described. The future challenges and important opportunities for the application of self-crimping technology in micro energy storage devices are summarized and prospected.
