Title:
BINDER FOR SILICON NEGATIVE ELECTRODE OF LITHIUM ION SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/239746
Kind Code:
A1
Abstract:
This bisiminoacenaphthene crosslinked polymer including a bisiminoacenaphthene crosslinked polymer in which a repeating unit represented by formula (I) (Ｘ- represents a monovalent anion, Y represents a linking group, and Z represents a divalent organic group.) is crosslinked with a repeating unit represented by another formula (I) via a linking group Y exhibits excellent charge/discharge durability and has large discharge capacity. The bisiminoacenaphthene crosslinked polymer is thus used for a binder for a silicon negative electrode of a lithium ion secondary battery and a lithium ion secondary battery including a silicon negative electrode containing the binder for a silicon negative electrode.
