THE STATE OF SURFACE-LAYERS ON LITHIUM IN MODIFIED NONAQUEOUS MEDIA

The state of lithium electrode surface after contact with triethylamin e-modified propylene carbonate solutions of lithium perchlorate was st udied using the pulse galvanostatic technique as well as methods of SI MS and electron microscopy. It was shown that amine added into the sol utions stabilizes the state of lithium and prevents the formation of a secondary porous passive film on the lithium surface. Chemical compos ition of the primary film remains unchanged. Certain properties of pas sive films formed in electrolyte solutions studied were evaluated.
