Results on the production of stable light nuclei, including deuterons, $^{3}\rm{He}$, $^{4}\rm{He}$ and the corresponding anti-nuclei, in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV and $\sqrt{s_{\rm NN}}$ = 5.02 TeV will be presented and compared with theoretical predictions to provide insight into the production mechanisms in heavy-ion collisions.

These information will be complemented by new results on the elliptic flow of (anti-)deuterons and $^{3}\rm{He}$. While one of the approaches to describe the elliptic flow of hadrons and light nuclei is given by quark coalescence, the production of light nuclei is also depicted as a coalescence of nucleons, i.e. hadron coalescence. Differences should be visible for those two approaches when the elliptic flow is measured simultaneously with the transverse momentum ($p_{\rm T}$) spectra, especially when they are scaled by their number of nucleons and quarks.

The experimental results will be presented giving a critical view of their comparison to the expectations from coalescence and hydrodynamic models that aim at describing both the $p_{\rm T}$-spectra and the elliptic flow.
