During the 2yr mission, TESS 2min cadence mode obtained high-precision photometry of more than 200,000 objects distributed over almost the entire sky. Among these objects, we identify 368 EEBs, including 23 newly discovered systems, through a detailed analysis of periods, light-curve shapes, and eclipses. We have also adopted the two recent TESS-based eclipsing binary catalogs, bringing our sample size to 514. The eccentricity, argument of periastron, absolute magnitude, and intrinsic color are determined for these EEBs. We find the absolute magnitude MG of EEBs has a span of at least 20mag. Stars as low as 0.15M_{sun}_ and as high as 30M_{sun}_ can have an eccentric orbit. Based on the parameters of Gaia Radial Velocity Spectrometer spectra, we find four EEBs contain evolved components, namely, TIC146039664, TIC141809359, TIC428249301, and TIC294261093. Overall, more luminous EEBs have a shorter circularization period. There are peculiarities in the eccentricity distribution of the brightest and faintest EEBs (M_G_<1 and M_G_>5). The former may not have a strict cutoff circularization period, while the latter may still have an eccentric orbit at periods shorter than 1day.2025AJ....170..356Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/170/356CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/355 : Gaia DR3 Part 1.
