摘要：

The complex correlation between Mn 3+ ions and the disordered phase in the lattice structure of high voltage spinel, and its effect on the charge transport properties, are revealed through a combination of experimental study and computer simulations. Superior cycling stability is achieved in LiNi 0.45Cr 0.05Mn 1.5O 4 with carefully controlled Mn 3+ concentration. At 250th cycle, capacity retention is 99.6% along with excellent rate capabilities.
