A hierarchical carbon nanotube-loaded glass-filter composite paper interlayer with outstanding electrolyte uptake properties for high-performance lithium-sulphur batteries

Abstract

A hierarchical CNT-loaded GF composite paper interlayer was fabricated by a sonication method. In this study, the GF paper offers outstanding electrolyte uptake, which is essential for preserving dissolved polysulphides, and the CNT networks provide a fast electron pathway for insulating the active materials. The GF/CNT interlayer-loaded Li-S cell exhibited a high capacity and long-term cycling performance.
