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. 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 …
