ABSTRACT:
Provided is a nonaqueous electrolyte element for use in secondary battery cells which comprises an effective lithium stripping enhancing amount of one or more soluble materials, such as a lithium polysulfide, which increases the lithium stripping efficiency. Also provided is a secondary lithium battery cell comprising said nonaqueous electrolyte element. Such a nonaqueous electrolyte element can be advantageously used in the manufacture of secondary electric-current producing cell elements, and provides many advantages in achieving extended cycle life and increased safety of secondary lithium batteries.
