摘要：
The zone-center phonons of spinel structure lithium manganese oxide have been investigated by applying de Launey angular force constant model. The calculation is extended to lithium extracted phases Li0.5Mn2O4 and Li0.015Mn2O4 also. The lattice phonons thus obtained are compared with available experimental results. The lithiation effects on phonon modes are also discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
