摘要：

Lithium has been intercalated in LiW3O9F. This phase exhibits a peculiar packing of hexagonal tungsten bronze layers. Up to two lithium atoms can be intercalated reversibly. If the Li3W3O9F composition is overpassed the reaction becomes irreversible and an amorphization occurs. The variation of the diffusion coefficient versus the amount of lithium has been determined from the electrochemical relaxation curves. An NMR study has shown that Li+ ions are not mobile in LiW3O9F and have a high mobility in intercalated materials at RT. © 1990.
