【Abstract】 Lithium-sulfur battery has high theoretical specific capacity and energy density, which makes it a promising candidate as the next-generation energy storage device. In the research and development of lithium-sulfur batteries, nanocellulose-based materials have attracted extensive attention due to their unique network structure and the physicochemical properties. The present paper starts by introducing the basics of lithium-sulfur battery, and further analyzes the challenges hindering its commercialization. The paper also reviews the latest research of nanocellulose-based materials in lithium-sulfur batteries, from the perspectives of the unique structure and excellent performance of nanocellulose. It can be concluded that nanocellulose-based materials can serve as separators, cathode materials, and other components, and can alleviate critical problems is Li-S battries including ‘shuttle effect’, ‘volume expansion’ and ‘lithium dendrite’, and also significantly improve the electrochemical performance and service life. Finally, the challenges to nanocellulose-based composites and the outlook for cellulose-based lithium-sulfur batteries are discussed.更多还原
