Cellulose-based material in lithium-sulfur batteries: A review

Lithium-sulfur (Li-S) battery is considered to be a promising energy storage system due to its high energy density and low cost. However, the commercialization of Li-S battery is hindered by several problems such as the insulating nature of active materials, notorious shuttle effect and damage of lithium dendrites. Cellulose-based materials have attracted widespread attention in the development of Li-S battery on account of their environmentally friendly nature, unique network structure, and possibility for chemical functionalization. This review summarizes the application of cellulose-based materials in Li-S batteries mainly as either the separator, the carbon material for binder assisted modification of separator or as carbon hosts for sulfur cathode and discusses the challenges that utilization of the cellulose-based materials could potentially encountered in Li-S battery. Perspectives regarding the future development of cellulose-based materials for Li-S battery are also discussed.

Automated summary

Cellulose-based materials have shown promising applications in Li-S batteries as separator, carbon materials for binder assisted modification, and carbon hosts for sulfur cathode. Despite the challenges, there is potential for further development and utilization of cellulose-based materials in Li-S batteries.
