Abstract
. The energy density retention rate of AC-24 is 71.1% with the power density increased by about 110 times, indicating excellent rate capability. Additionally, a capacitance retention rate of about 95% after 3000 cycles implies an outstanding cycle lifetime of an AC-24-based capacitor. The freezing strategy developed here provides a novel route for low-cost and eco-friendly production of AC from biomass wastes for high-performance supercapacitors.
