Reengineering Cathode Interfaces Via Electrochemical Fluorination In article number 2200035, Bishnu P. Thapaliya, Sheng Dai, and co-workers develop electrochemical fluorination (ECF) to reengineer the interface of high-capacity cathodes by forming conformal LiF layer. The ECF can tune the LiF layer thickness, resulting in a robust cathode electrolyte interphase (CEI), which in turn results in enhanced electrochemical performance. Additionally, ECF is cost-effective and free from all the hazards associated with state-of-the-art fluorination that ensure its easy industrial upscaling.
