Podsumowanie kontekstu i ogólnych celów projektu

The global effort to achieve a climate-neutral society and reduce the environmental impact of fossil fuel usage has accelerated the adoption of renewable energy sources, driving an increased demand for energy storage systems (ESS) to manage the intermittency of renewable energy generation. Energy storage devices (ESDs), such as supercapacitors (SCs), play a crucial role in wearable electronics and hybrid electric vehicles due to their high power density and long cycle life, which support the green energy transition. The SASPE project focused on employing a binder-free electrode design to achieve more efficient supercapacitor technology. By integrating renewable and pollution-free energy sources with advanced energy storage systems, the SASPE project emphasized sustainable practices throughout its execution and aligned with the United Nations Sustainable Development Goals (SDGs) to achieve zero-emission transportation systems and foster a sustainable future. Through the development of eco-friendly energy materials and energy storage technologies, the project addressed key global challenges, such as promoting affordable and clean energy, advancing sustainability, and reducing environmental impact.
The project aimed to develop 2D materials-based binder-free electrodes using environmentally friendly materials, offering a sustainable alternative to the conventional slurry-based method commonly used in electrode preparation. The binder-free approach not only simplifies the electrode preparation process by reducing the number of steps but also enhances the overall performance of the electrodes by improving their electrical conductivity and stability. The project also focused on developing solid state supercapacitor using solid polymer electrolyte for addressing the self-discharge issues of SCs.

Prace wykonane od początku projektu do końca okresu sprawozdawczego oraz najważniejsze dotychczasowe rezultaty

The SASPE project focused on fabricating large-area, 2D materials-based binder-free electrodes, developing a polymer-based electrolyte, and assembling supercapacitors using the developed electrodes. Extensive material characterization and analysis were performed, along with device testing, to ensure optimal performance.
One of the key findings was that the electrochemical performance of the supercapacitor assembled with a large-area electrode (25 cm²) was consistent with that of a supercapacitor using a smaller electrode size (1 cm²), demonstrating the scalability of the technology without compromising its performance.
The significant results of the project have been published in the peer-reviewed journal RSC Nanoscale Advances (Nanoscale Adv., 2024, 6, 4647-4656, DOI: 10.1039/D4NA00368C). Furthermore, the project exceeded its original commitments, enabling the preparation of two additional manuscripts currently underway. The SASPE project results were showcased at the prestigious European Materials Research Society (E-MRS) Spring Meeting, held from May 29 to June 2, 2023, at the Convention & Exhibition Centre in Strasbourg, France. The findings were also shared with the broader community through engaging outreach activities, including participation in the European Researchers' Night program. These efforts highlight the project's commitment to advancing scientific knowledge and fostering public engagement with cutting-edge research.

Innowacyjność oraz oczekiwany potencjalny wpływ (w tym dotychczasowe znaczenie społeczno-gospodarcze i szersze implikacje społeczne projektu)

This project has advanced beyond the current state of the art, particularly in developing large-area supercapacitor electrodes and conducting device testing on electrodes of size 25 cm². These developments demonstrate the scalability and potential for real-world applications of the technology. Continued research will focus on optimizing these materials for commercial use to meet the demands of modern energy storage systems.
The development of advanced electrode materials not only achieved the project's primary goals but also delivered additional outcomes, further highlighting the multidisciplinary potential of the SASPE project. These advancements contribute to sustainable energy solutions by supporting the green energy transition and aligning with the UN’s SDGs. The fellow organized numerous events during the fellowship to engage the public and a broader audience, raising awareness about the project’s significance and the importance of addressing environmental challenges. These efforts aimed to highlight the role of sustainable energy solutions in mitigating environmental issues and fostering a carbon neutral society.
