Asymmetrical Functionalization of Polarizable Interface Restructuring Molecules for Rapid and Longer Operative Lithium Metal Batteries (Small 51/2024)

Lithium Metal Batteries In article number 2405143, Baoyu Liu, Shuiqing Yang, Haiqun Chen, Yi Huang, and co‐workers demonstrate that 3‐mercapto‐1‐propanesulfonic acid sodium salt (MPS), with its asymmetrically functionalized thiol and sulfonate groups, acts as an interface‐restructuring and surface‐flattening agent for long and rapid operation in Li metal batteries. This study introduces a new class of electrolyte additives for Li metal batteries by controlling functional groups and polarizable properties.
