Hard Carbon Fibers Pyrolyzed from Wool As High-Performance Anode for Sodium-Ion Batteries

Abstract

In this paper, we first demonstrate that the wool from worn-out clothes can serve as a low-cost and easy-to-collect precurs or to preparing high-performance hard carbons for Na-ion batteries. Morphological characterizations demonstrate that this wool-derived hard carbon presents well-defined and homogeneously dispersed fiber networks.
