Abstract:
In this study, a high-load self-supporting thick carbon electrode (35.2 mg cm-2) was constructed by hot-pressing densification combined with KOH activation of natural wood. Its hierarchical pore structure synergistically optimizes energy storage performance (3.5 F cm-2) and provides a new strategy for the practical application of supercapacitors.
