Recently, the rapid development of foldable, rollable displays and electronic devices are accelerating an increasing necessity of flexible and miniaturized energy storages such as micro-supercapacitors (MSCs). However, many attempts have drawbacks such as materials, energy and time consuming and require multiple steps. In this study, we have fabricated flexible asymmetric hybrid MSCs by using a printing technique and an intense pulsed white light (IPWL) technology. By these methods, micron-sized electrode patterns can be easily fabricated on flexible substrate and reduced graphene oxide and metal oxide micro-patterns can be accomplished within milliseconds by irradiating the IPWL with high energy density on graphene oxide and metal oxide precursor patterns, which is exceptionally faster than other graphene reduction and metal oxide formation methods. The prepared micro-patterns are utilized as MSC electrodes, and their electrochemical performance and characteristics are discussed. |
