Abstract:

In this study we investigated the formation of protective surface films on in situ freshly Li in LiAlCl4SOCl2 electrolytes using electro-chemical techniques. Based on the results we propose a film model consisting of three region. Region I forms rapidly less than one hour upon exposure of a fresh surface. It has a thickness between 200 and 400 A and an apparent resistivity of -2.10 7 cm. It appears to have significant imperfection and some microporosity along the grain boundaries. This is followed by a Region II film which is more ordered and more compact. Its resistivity is approximately 2.l0 to the 8th power cm and it grows to 200 to 600 A within a 20 hour period. Further growth is slow. Author
