Printed Supercaps and Batteries (Supercapatteries) for Smart Energy Storage Systems [SUPERBAT]
Duration: 04/01/2022 – 03/31/2024
Powerful, mass printed, 3D energy storage devices, realised by:
- Material/ink development for printed supercaps and batteries with hybrid electrodes to be used as supercapattery with focus on environmentally friendliness (e.g. substrate = paper; electrodes = graphene oxide…)
- R2R process development for single and multilayer 3D devices (printing and postpress)
- Hybrid smart power management electronics, integrated to energy storage device
- Development of demos for target applications (e.g. power system for sensor/actuator

Our daily life is more and more influenced by multiple electronic devices. Terms like “electronics everywhere” and the “Internet-of-things” (IoT) are becoming reality and are trying to transfer step-by-step the world into a smart one: From big smart cities over smart home to small smart packaging and much more. What all of these mega-trends have in common is the need for an effective and environmentally friendly electrical power supply which should consist of a renewable energy source and a “green” solution for energy storage especially for energy autarkic solutions.
For the energy storage, usually (rechargeable) batteries or in more specific cases supercapacitors (SCs) are chosen. SCs are commonly used as an alternative to rechargeable batteries when a quick energy boost is needed. However, the energy density of SCs is much lower than of batteries. But some of the advantages such as high capacitance, excellent power density, and impressive efficiency make them attractive for some applications. Besides, while the self-discharging problem is a very important challenge for SCs, low cycle life and safety-related concerns are other challenges for batteries.
Considering all this information, SUPERBAT focuses on combining the best features of SCs and rechargeable batteries by developing a roll-to-roll (R2R) mass printed low-cost, environmentally friendly and safe supercapattery (a combination of supercapacitor and battery) which can be used for powering flexible electronic systems e.g. in the area of healthcare, smart packaging and many more future IoT applications. As the manufacturing technology is scalable, in a second phase of the project, 3D architectures of supercapattery systems by using highly efficient post-press technologies will be developed providing an even higher capacitance. Such 3D systems will be attractive for applications with higher and variable power and energy requirements, e.g. as needed for drones.
For the realisation of smart energy storage systems, hybrid (printed electronics + discrete tiny Si-devices) smart power management electronics will be developed and smoothly integrated to the printed supercapattery to make an early adaptation of the printed energy storage system to real applications possible.
To the best of our knowledge, such a printed energy storage system with supercapattery approach and integrated hybrid power management electronics has not been shown before clearly indicating the innovative and pre-competitive character of the project.
SUPERBAT will be conducted by three research institutions from two countries, Germany and Turkey. While Sakarya University, Faculty of Engineering, Metallurgical and Materials Engineering, is a specialist for the development of novel battery systems, materials and processes, TU Chemnitz with its Institute for Print and Media Technology is one of the pioneers in the field of printed electronics including printed energy storage devices. With its high reputation in the field of cutting-edge electronic developments, TU Dresden with its Professur für Schaltungstechnik und Netzwerktheorie will contribute to the electronics side of the project. The project coordination is conducted by 3D MID e.V. Together with Sakarya Teknokent, both associations will bring the project results to their wide range of members from industry and academia.
The project will be supported and advised by a large SME User Committee (SME UC) with 14 companies covering the whole value chain from materials/inks, over printing related companies until energy storage device specialists and end users from Germany and Turkey showing the great interest of our approach and the need for further developments for this future-looking research field of novel and innovative energy storage devices.
