A facile Schiff base chemical approach: towards molecular-scale engineering of N-C interface for high performance lithium-sulfur batteries

An interwoven coaxial cable network with ultrahigh nitrogen content is successfully fabricated through engineering a rationally designed Schiff-base chemistry. This in-situ bottom-up strategy enables the targeted heteroatom doping throughout the entire networks on molecular scale, and the obtained homogenous N-C interface is demonstrated to play the key role in facilitating the chemical absorption of sulfur/polysulfides.308
