Challenging Prevalent Solid Electrolyte Interphase (SEI) Models: An Atom Probe Tomography Study on a Commercial Graphite Electrode

“…This translates to a ratio of absolute boiling/decomposition temperatures of lithium fluoride to polyolefins in the range of 3–4. Differences in the bonding situation lead to a preferential evaporation of specific microphases and to a slower evaporation/decomposition of laterally neighboring microphases, resulting in a distortion of their vertical positions . Despite this distortion, the lateral and vertical sequence of the microphases observed here will however be retained.…”

“…Differences in the bonding situation lead to a preferential evaporation of specific microphases and to a slower evaporation/ decomposition of laterally neighboring microphases, resulting in a distortion of their vertical positions. 31 Despite this distortion, the lateral and vertical sequence of the microphases observed here will however be retained. This can be reasoned from studies of biominerals, in which extreme evaporation field differences were also relevant.…”

“…The APT analysis was done with a CAMECA LEAP 5000XS, operated in UV laser pulsing mode with a frequency of 200 kHz and a detection rate of 2%. The base temperature was set at 40 K, and the laser energy was adjusted to obtain an equivalent pulse fraction of 25% of the DC voltage to avoid preferential evaporation 64 (i.e., around 100 pJ). Data reconstruction and processing were performed using the AP Suite 6.1 software tool and the Norwegian Atom Probe App (NAPA) software, developed in MATLAB.…”

“…Additional examples include oxides, like SiO 2 , which commonly exhibit small deficiencies in oxygen not explained by the misidentification of overlapping O + and O 2 ++ ions (Kinno et al, 2014), and a number of atom types and features which seem more prone to correlated evaporation (De Geuser et al, 2007) than the rest of the periodic chart: carbon and carbides (Yao et al, 2010; Kitaguchi et al, 2014; Lewis et al, 2015; Thuvander et al, 2019), boron and borides (Menand & Kingham, 1984, 1985; Menand et al, 1984; Ronsheim et al, 2008; Larson et al, 2011; Meisenkothen et al, 2015, 2020b), iron (Rolander & Andren, 1989; Takahashi et al, 2011; Kitaguchi et al, 2014), and clusters (Marquis & Hyde, 2010). The possibility that different atoms or materials possess unique correlated evaporation properties will complicate any approach to universally correct for this phenomenon (Cerezo et al, 1984; Rolander & Andren, 1989; Rolander & Andren, 1994; Da Costa et al, 2012; Stephan et al, 2015; Hatzoglou et al, 2020).…”
