dc.description.abstract | Hemp-fibers have a long history as a source of making paper, ropes, and canvas. Recently, due to their superior mechanical strength with biodegradability, hemp-fibers are resurfacing as an environmentally friendly engineering material. Meanwhile, lithium-sulfur batteries are receiving substantial attention for the next-generation rechargeable batteries, owing to their high energy density combined with the natural abundance of sulfur. Despite these advantages, sulfur active materials still encompass a number of challenges for practical applications, such as intrinsically low electrical conductivity, dissolution in the electrolyte and limited areal loading. By utilizing hemp-fibers as a scaffold for the sulfur active material, herein we report the fabrication of a hybrid porous carbon architecture that mimics the resource acquisition and transport system of vascular plants. The hemp fiber-derived hybrid electrodes show an exceptionally high sulfur loading of 15.36 mg cm(-2) and display a high areal capacity of 14.8 mA h cm(-2) at 0.1C current rate. We also demonstrate the feasibility of the practical application by fabricating large-area pouch-cells. Furthermore, our operando Raman and X-ray photoelectron spectroscopy studies have revealed the chemisorption mechanism of the hemp hybrid electrode with lithium polysulfide, which enables long cycle life. | - |
