Lithium abundances in a sample of halo dwarfs have been redetermined by using the new Teff derived by Fuhrmann et al (1994) from modelling of the Balmer lines. These Teff are reddening independent, homogeneous and of higher quality than those based on broad band photometry. Abundances have been derived by generating new atmospheric models by using the ATLAS-9 code by Kurucz (1993) with enhanced α-elements and without the overshooting option. The revised abundances show a remarkably flat \it plateau in the Li-Teff plane for Teff> 5700 K with no evidence of trend with Teff or falloff at the hottest edge. Li abundances are not correlated with metallicity for [Fe/H] 5700 K and [Fe/H]≤ -1.4, is [Li] = 2.210 ± 0.013, or 2.224 when non-LTE corrections by Carlsson et al (1994) are considered.
