      abstract     = {Partial electrification of vehicles with conventional
                      combustion engines is an effective method to enhance
                      efficiency and reduce CO2 emissions. One way of adding a
                      so-called mild hybridization to existing vehicle
                      architectures is to extend the conventional 12V vehicle
                      electrical system by a 48V voltage level that contains a 48V
                      lithium-ion battery. A promising anode material for such a
                      battery is lithium titanate oxide (LTO), which possesses
                      several outstanding material properties including high-power
                      capability, inherent safety and excellent lifetime
                      performance. Extensive scientific studies on mass-produced
                      LTO-based cells are rare, resulting in a lack of essential
                      information on performance and aging behavior. Based on
                      characteristic 48V battery operating conditions this thesis
                      addresses this knowledge gap. It assesses the suitability of
                      an LTO-based cell type for low voltage vehicle systems by
                      reporting essential performance and aging characteristics.
                      The investigated LTO-based cells show excellent power
                      capability and cycle stability, even at high ambient
                      temperatures and high current rates, and meet the vehicle
                      relevant lifetime requirements of 200,000 km. The calendar
                      aging behavior is strongly dependent on temperature and
                      state of charge. This can be attributed to both reversible
                      capacity effects caused by an overhang of the electrodes as
                      well as irreversible aging mechanisms such as (passivating)
                      surface layer formation and gas formation.},
