      abstract     = {The high-voltage spinel LiNi0.5Mn1.5O4 is one of the most
                      promising candidates for use in high-energy-density
                      lithium-ion batteries. To investigate the influence of the
                      synthesis method and the resulting particle morphology on
                      the electrochemical performance, performance degradation,
                      and aging, different synthesis routes for LiNi0.5Mn1.5O4
                      were evaluated in this study. Inhomogeneous transition metal
                      cation intermixing and exposure to high temperatures during
                      synthesis led to the formation of a small amount of
                      impurities, which had a severe impact on the electrochemical
                      performance. Furthermore, the particle morphology influences
                      the electrolyte decomposition and the formation of the
                      cathode electrolyte interphase (CEI) on the surface of
                      particles. Moreover, transition metal dissolution was
                      investigated by analyzing the Ni and Mn content in the
                      electrolyte after constant current charge–discharge
                      cycling. The results suggest that an unstable delithiated
                      structure at high potentials leads to the dissolution of Mn
                      and Ni into the electrolyte, whereas the particle morphology
                      had only a minor influence on the extent of transition metal
                      dissolution.},
