WebToday, lithium metal is only used as an anode in non-rechargeable batteries, to avoid this shorting risk. The cryo-STEM revealed a layer of lithium ethylene dicarbonate at the solid-electrolyte interphase (SEI) … WebSeveral types of solid carbonate species, including lithium ethylene dicarbonate (LiEDC), lithium ethylene monocarbonate (LiEMC), and lithium carbonate (Li2CO3) have been observed in the graphite SEI formed under EC-containing electrolytes2–5. It is generally agreed that LiEDC deposits first via the reduction of EC, as shown in Reaction S93.
WebEC, because of its high reduction limit (∼1.0 V vs Li), is usually reduced via a single-electron process before the rest of the electrolyte components, and the corresponding reduction compound (lithium ethylene dicarbonate (LEDC)) is believed to be responsible for a stable interphase that supports the reversible operation of lithium-ion chemistry. WebRecently, Wang et al. revealed (di)lithium ethylene monocarbonate ((D)LEMC) as the main SEI component present. 11 Based on LEMC or DLEMC being the major SEI component and therefore, likely involved in most carbonate decomposition pathways, electrochemical carbonate decomposition was defined more precisely with an analytical study of a 13 C 3 …
