O projektu

Supercapacitors (SCs) represent one of the most promising energy storage technologies because of their remarkable features, such as ultrahigh power density (>10 kW kg-1), ultralong cycling life (>10,000 cycles). The bottleneck that limits the wide application of SC technology lies in its relatively lower energy density compared with other commercially available energy storage technologies. In this regard, developing innovative functional electrode materials offers great opportunity to achieve performance breakthrough for the next-generation supercapacitors. This project aims at demonstrating the application of the 2D hybrids concept as high-performance electrode materials for SCs. Based on MXenes and black phosphorous, a series of 2D hybrids will be rationally designed and fabricated. The obtained 2D hybrids will significantly address the e re-stacking problem faced by 2D materials and the instinct drawbacks of MXene (poor chemical stability) and BP (low conductivity and poor chemical stability). With the assistance of the multi-scale material characterization technologies, the project will generate new knowledge of fundamental mechanism underlying hybrid structures for efficient SCs. Based on the developed 2D hybrids, this project will also fabricate two kinds of state-of-the-art SC devices, namely thin-film SCs (energy densities >20 Wh kg-1, power densities >100 kW kg-1, cycling life >5000 cycles) and microsupercapacitors (energy densities >1 μWh cm-2, power densities >1 mW cm-2, cycling life >5000 cycles). These advanced SCs will demonstrate great potentials as the power source for the emerging portable and micro- electronics. The project will address both fundamental (material science) and technological issues (device development), which will strengthen the innovation of excellence of the academic partners. The success of this project will promote the efficient utilization of renewable energy sources, which fully meet the European strategic policy targets in terms of greenhouse gas emission reduction and developing affordable sustainable energy sources and usage.
