A renaissance for lithium-sulfur batteries through low-cost, efficient, and sustainable biomass cathodes

Although lithium-ion batteries face material sustainability issues, one promising alternative—lithium-sulfur (Li-S) batteries—suffers from destructive chemical reactions. Recently in Chem, Hou et al. proposed one viable solution: an encapsulating lithium polysulfide electrolyte. We discuss this advance and the potential role of biomass as an alternative sustainable material for Li-S battery cathodes.
