摘要：

The tetragonal crystalline modification of LiFeO2 was subjected to partial proton exchange reactions by hydrothermal treatment at 160°C in distilled water. The product after 1 day treatment had a Li/Fe ratio of ca. 0.15. A partial displacement of octahedrally coordinated Fe(III) ions to A sites of a spinel-related structure was observed. The presence of hydrogen in the structure was shown by water release reactions between 300 and 500°C. The product treated at 800°C was a mixture of LiFe5O8 and α-Fe2O3. © 1990.
