Influence of preparation conditions on electronic resistivity of LiFeO/sub 2/ synthesized in molten carbonates

Conference ·
OSTI ID:6342828
; ;
LiFeO/sub 2/ has been synthesized in molten Li/sub 2/CO/sub 3/-K/sub 2/CO/sub 3/ eutectic at different temperatures and under different gas environments. The electronic resistivity of LiFeO/sub 2/ was found to be dependent on the partial pressure of CO/sub 2/ above the carbonate melt. A model for nonstoichiometric LiFeO/sub 2/ has been proposed to explain these experimental results. Dependence of resistivity on the synthesis temperature was also observed.
