In Situ Polymerization of PANI to Uniformly Coat Lignin-Based Carbon Fibers for High-Performance Supercapacitors
Lignin is abundant and renewable, and its high-value utilization in carbon-based supercapacitor electrodes has attracted considerable attention. However, pure lignin-based carbon fibers (LCFs) have insufficient active sites, and direct loading of polyaniline (PANI) easily causes agglomeration, limiting their electroc...
