  Most metal-rich AGB/RGB stars present strong Li underabundances, since this
element is easily destroyed in the high temperatures of the stellar interiors.
In spite of this fact, several of these stars are Li-rich, having Li abundances
given by log (Li/H) + 12 > 1.5. In the present work, we extend our previous
investigation on AGB/RGB stars to the expected mass loss rates of these stars.
Specifically, we look for correlations between the Li abundances and the mass
loss rates or related parameters in Li-rich AGB/RGB stars. We have estimated
the mass loss rates using a modified form of the Reimers formula and applied it
to a large sample of 104 Li-rich giant stars for which reliable stellar data
are available. Our proposed method assumes a linear relation between the
stellar luminosity and the Li abundance, so that the luminosity can be
estimated from the Li abundance. The stellar mass is then obtained from the
effective temperature and luminosity using recent evolutionary tracks. The
stellar radius can be determined from the stellar gravity, so that the mass
loss rate can be calculated using an adequate calibration involving both
Li-rich and Li-poor stars in the AGB/RGB branches. The results show that most
Li-rich stars have lower mass loss rates compared with C-rich or O-rich giants
that do not present Li enhancements.
