Transport properties of LiMn2O4

Abstract This paper presents the high temperature measurements of electrical conductivity and thermoelectric power of LiMn 2 O 4 as a function of temperature (870–1070 K) and oxygen pressure (2·10 −6 –1 atm) in thermodynamic equilibrium conditions in order to assess the structure of point defects in this material. The electrical properties have been analysed with reference to those concerning deviation from stoichiometry.
