Abstract
The present application describes the use of a solid electrolyte interphase (SEI) fluorinating precursor and/or an SEI fluorinating compound to coat an electrode material and create an artificial SEI layer. These modifications may increase surface passivation of the electrodes, SEI robustness, and structural stability of the silicon-containing electrodes.
