New paper on self-assembled organic nanowires for batteries and metal-ion supercapacitors published in Energy & Environmental Science

Our latest research in Energy & Environmental Science explores an eco-friendly, high-performance lithium-ion anode made from self-assembled organic nanowires. By evaporating water on a copper current collector, we achieved a nanowire network without harmful solvents, enhancing lithium-ion diffusion and storage capabilities. The result? The self-assembled organic nanowire anode delivers a remarkable lithium storage capacity of up to 1888 mA h/g at 0.1 A/g, retaining 508 mA h/g even at a high current rate of 10 A/g. In lithium-ion capacitors, it achieves a specific energy of 156 W h/kg at 0.34 kW/kg and maintains 60.2 W h/kg at 19.4 kW/kg, outperforming many state-of-the-art systems.
