Abstract:

With the progress of human society, wearable electronic devices are becoming more and more desired. Furthermore, there is an increasing demand in stretchability of energy storage devices which have been widely applied to electronic skin, implantable sensors and other portable devices. In this work, several preparation strategies for stretchable Lithium-ion batteries and supercapacitors have been systematically introduced and reviewed on the basis of electrodes, common electrolytes for stretchable electrochemical energy storage devices as well as their strengths and weaknesses have been concluded. Besides, the integration of stretchable energy storage devices has also been showed in this paper. Finally, some challenges and perspectives towards the stretchable energy electrochemical storage devices（SEESDs）have been summarized.

Key words: stretchability, electrochemical energy storage, supercapacitors, lithium-ion batteries
