Measurement of Li/sup +/ ion transport numbers in PEO-LiX complexes. Technical report No. 16, 15 July 1985-January 1988
Lithium-ion conducting-polymer materials are being intensively investigated in a number of research laboratories because of their potential use as solid electrolytes in high-energy-density solid-state lithium batteries. The most-widely used polymer were based on polyethylene oxide (PEO). The conduction mechanism in these polymer electrolytes has generally been assumed to be due to Li(+)ion transport from one lone pair site to another along the helical PEO strands. However, recent studies have shown that the Li(+) transport number is less than unity. The transport number for Li(+) ions in PEO-LiX complexes was measured using a potentiostatic polarization technique. The results indicate that the Li(+) ion transport is strongly influenced by the salt concentration and the type of counter ions.
