Stretchable Hetero-nanostructures for Wearable Energy Storage Devices
|
박상백 교수 KIST Stretchable energy storage devices that can accommodate large strain while retaining their electrochemical functions are the key components to power elastomeric electronics and make them truly autonomous systems. Many efforts have been made to improve the electrochemical energy performance using various morphologies of nanomaterials as the electrodes. However, a single-component electrode material can hardly obtain the characteristics of high electronic/ionic conductivity, high electrochemical and mechanical stability, simultaneously. Therefore, designing well-arranged hetero-nanostructures that overcome the limitations of different electrochemically active materials and combine the advantages of them is of great significance and still remains a challenge. Herein, we extend hetero-nanostructure strategy to the emerging battery technologies for wearables. It contributes to the development of advanced electrodes, enabling wearable batteries to be high performance as well as multifunctional - transparent, electrochromic, integrated, or self-healing. Therefore, ongoing efforts to explore novel hetero-nanostructures will achieve a breakthrough in soft energy storage system. |
