Tailoring Microstructure of Lignin-Derived Hard Carbon Nanofibers via Molecular Stitching for Enhanced Sodium-Ion Storage
Renewable lignin is an attractive biomass precursor for sustainable hard carbon in sodium-ion batteries (SIBs) owing to its renewability, high carbon yield, and intrinsically molecular disordered structure. However, severe structural collapse during carbonization and low initial coulombic efficiency (ICE) hinder its...
