Synthsis and structures of lithium manganese oxide spinel, LiMn_2O_4-δ (O≤δ≤0.27)

摘要

Lithium manganese oxides spinels were synthesized under various synthesis conditions and their structures were determined by TOF neutron powder diffraction measurements. Oxygen vacancies exist for the samples synthesize above 800deg.c, and the mount of vacancies was found to be sensitive to the synthesis conditions.
