Other network products include species with ester, carboxylate, and oxide functional groups, such as lithium 2-(formyloxy)ethan-1-olate, which we abbreviate as LFEO, as well as a number of cyclic species, such as 4,4',5,5'-tetrahydro-2,2'-bi(1,3dioxolylidene), which we abbreviate as bi-dioxolylidene. LFEO and bi-dioxolylidene (Fig. dashed purple) were particularly unexpected given how distinct they are from other predicted SEI products and, in particular, the experimentally identified products. Evaluating whether or not these products will actually form in the SEI necessitates considering energy barriers, kinetics, and reactive competition. Using the shortest paths from stochastic network analysis to guide automated transition-state calculations, we identified elementary formation mechanisms to both LFEO and bi-dioxolylidene to evaluate their potential to participate in SEI formation (see CRN-Derived Elementary Mechanisms to Form Unexpected Network Products).
