A study of 3D printed flexible supercapacitors onto silicone rubber substrates

© 2017 The Author(s). The rapid development of flexible energy storage devices is crucial for various electronics industries. Highly flexible electrochemical double layer capacitors (EDLCs) can be manufactured by 3D printing technology. It was a great challenge to fabricate multiple material layers of the EDLC in one rapid and accurate deposition event. The fabricated structures were composed of twelve electrodes which could be configured in a number of different ways in one block module. This work aims to investigate the performance of the flexible EDLCs manufactured by 3D printing in a honeycomb pattern. The EDLC cells were fabricated using a slurry made from commercial activated carbon (AC) and a gel electrolyte deposited on a transparent silicone substrate. The flexible EDLCs structures can be used in flexible electronics with different patterns and sizes using 3D printer and can be applied to many applications such as wearable technology.Ministry of Higher Education and Scientific Research of Libya

3D printing of highly flexible supercapacitor designed for wearable energy storage

© 2017 The Authors. The rapid development of flexible energy storage devices is crucial for various applications. However, it is still difficult to manufacture functional flexible electrochemical double layer capacitors (EDLCs) in one single process due to many different types of materials being used in EDLCs. This paper presents a novel method of manufacturing highly flexible EDLCs by using an open source 3D printer. The EDLC components were fabricated using a single paste extrusion in a layer wise manner. The detailed fabrication process for a highly flexible EDLCs device has been demonstrated, where acetoxy silicone was used as the flexible substrate. The purpose of this study has been to develop a single continuous manufacturing process for EDLC and to investigate the electrochemical performances of 3D printed flexible supercapacitors. Mechanical bending tests were carried out to prove the stability of the electrochemical performance and flexibility of the 3D printed supercapacitors.Ministry of Higher Education and Scientific Research of Liby
