摘要：
Restraining soluble polysulfides from diffusing out of the cathode is fundamental to the development of high-performance lithium-sulfur batteries. The porous architecture and unique physicochemical characteristics of biomass-derived carbon materials makes it possible to improve the battery performance. Here, two types of porous carbon composites (NOSPC-1 and NOSPC-2) with insitu N, S and O tri-doping are obtained from yam via chemical activation. Structural analysis reveals that NOSPC-1 presents a highly graphitized interconnected micro-/mesoporous architecture. As a sulfur host, NOSPC-1-800 with 70% sulfur initiates a high reversible discharge capacity of 1556mAhg(-1) at 0.2C. The cathode further exhibits superior rate performance and long cycle life with 401.2mAhg(-1) reversible capacity and more than 95% coulombic efficiency after 450 cycles at 1C. Our findings provide meaningful insights toward exploring novel biomass-derived carbon materials for advanced Li-S batteries.
