ChemInform Abstract
New experimental results show that the oxygen nonstoichiometric range in the spinel phase is small. The phase diagram is elucidated. Between 400 and 880 °C only spinels of composition Li1+xMn2-xO4 are stable. Between 880 and 980 °C a variety of different tetragonal Li—Mn spinel phases Li1-xMn2+xO4 exist. Below 400 °C spinels are stable only as Li4Mn5O12 and LiMn1.75O4.
