Fluorinated Solid-Electrolyte Interphase in High-Voltage Lithium Metal Batteries

Liquefied gas electrolytes for wide-temperature lithium metal batteries

“…Additionally, LiF, S-O, N-O species are formed by the decomposition of LiTFSI and FM, which are believed to promote a protective interphase. 43 Depth-profiling XPS was also applied to cycled Li metal anode interfaces in different electrolytes (Fig. S27-S29, ESI †).…”

Designing Advanced In Situ Electrode/Electrolyte Interphases for Wide Temperature Operation of 4.5 V Li||LiCoO2 Batteries

“…The significant presence of LiF, which possesses excellent electronic insulating capability and structure stability, can effectively protect the Li anode from further electrolyte side reactions. [15] The formation of S-and nitrogen (N)-containing anions (e.g.,…”

Engineering Wavy‐Nanostructured Anode Interphases with Fast Ion Transfer Kinetics: Toward Practical Li‐Metal Full Batteries

“…[ 30–32 ] Based on the improved electrochemical performances of LMBs with fluorinated interphases, LiF has long been considered as the key SEI components for Li‐metal dendrite suppression. [ 33,34 ] However, a recent cryo‐TEM study reveals that LiF cannot participate in the compact SEI layer nor does it passivate the newly deposited Li‐metal. [ 35 ] The true relationship between SEI chemistry, nanostructure and Li CE needs to be probed for the future development of practical Li‐metal anode.…”
