000001199 520__ $$aTime dependent CP-violation phenomena are a powerful tool to precisely measure fundamental parameters of the Standard Model and search for New Physics. The Belle II experiment is a substantial upgrade of the Belle detector and will operate at the SuperKEKB energy-asymmetric $e^+ e^-$ collider. The design luminosity of SuperKEKB is $8 \times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than the Belle experiment. This dataset will greatly improve the present knowledge, particularly on the CKM angles $\phi_1/\beta$ and $\phi_2/\alpha$ by measuring a wide spectrum of B-meson decays, including many with neutral particles in the final state. A study for the time-dependent analysis of $B^0\to\pi^0\pi^0$, relevant for the measurement of $\phi_2/\alpha$, and feasible only in the clean environment of an $e^+ e^-$ collider, will also be given.
