Phase equilibria involving solid solutions in the Li–Mn–O system

Phase equilibria involving LiMn 2 O 4- , Li 2 MnO 3- , LiMnO 2- , Mn 3 O 4- , and MnO-base solid solutions were studied with varied temperature and partial oxygen pressure. The P o 2 – T and x – y projections of the P – T – x – y phase diagram of the Li–Mn−O system were constructed, as well as the k...

Description
Summary:Phase equilibria involving LiMn 2 O 4- , Li 2 MnO 3- , LiMnO 2- , Mn 3 O 4- , and MnO-base solid solutions were studied with varied temperature and partial oxygen pressure. The P o 2 – T and x – y projections of the P – T – x – y phase diagram of the Li–Mn−O system were constructed, as well as the key x – y isotherms of the Li 2 O–MnO–MnO 2 quasi-ternary system. In some experiments, the authors’ hydride lithiation method was employed to prepare lithium-rich homogeneous three-component nonstoichiometric phases.
