Lean Electrolyte Batteries: Addressing Passivation in Lithium–Sulfur Battery Under Lean Electrolyte Condition (Adv. Funct. Mater. 38/2018)

In article number 1707234, NH4TFSI is presented as a functional electrolyte additive to alleviate the passivation of Li2S for Li-S batteries under lean electrolyte conditions by Yuyan Shao, Jun Liu, and co-workers. This additive enhances the dissociation of Li2S and facilitates the homogeneous formation of Li2S particles, which significantly promotes the reversibility and reaction kinetics of sulfur and extends the cycle life.
