Title:
NEGATIVE ELECTRODE COMPOSITE BODY AND SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/030333
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a countermeasure against deposition of an alkali metal in cases where the alkali metal is used as a negative electrode. The above-described problem is solved by a negative electrode composite body that contains: a negative electrode active material which contains, as main components, Li and an element M that is solid soluble in Li; and a substance X which has a higher redox potential than the negative electrode active material, or a substance X which does not have electrode activity.
