Researchers from Nanyang Technological University and Zhejiang University of Technology improve the cycling stability of Li metal batteries by using self-assembled monolayers (SAMs). The SAMs containing polar carboxylic groups are deposited on the aluminum oxide–coated polypropylene separator. SAMs enhance the formation of an LiF-rich solid electrolyte interphase (SEI), thereby promoting lithium-ion diffusion and mitigating lithium dendrite growth.
