Breakthrough in Nanotechnology: Researchers Develop High-Capacitance Supercapacitors
Scientists at Anhui Polytechnic University have made a significant discovery in the field of nanotechnology, developing a novel nanosphere-based supercapacitor that exhibits exceptional energy storage capabilities. In a study published in the ACS Applied Nano Materials journal, researchers led by Xianfu Li created a composite material by combining MoSe2 and NiFe-LDHs, resulting in a high-performance supercapacitor with a specific capacitance of 6790 mF cm(-2) at a current density of 2 mA cm(-2).
Key Takeaways:
