Abstract

Lithium sulfur (Li-S) batteries are viewed as a promising candidate for next-generation energy storage systems due to their high energy density, low cost and ease of manufacturing. However, rapid capacity decay caused by lithium polysulfide shuttle during charging/discharging processes hinder its practical application. In this work, we demonstrate a cellulose encapsulated carbon/sulfur core-shell structure for advanced Li-S batteries based on electrostatic spinning with coaxial spinnerets. Cellulose serves as an excellent
