Abstract (en)

[origin: WO2022126251A1] Polymer of formula (I), wherein nitrogen atoms are coordinated with a lithium atom in 0% to 100% of repetition units in the polymer, and each R1 in each individual repetition unit independently represents a bivalent group, wherein the bivalent groups are, independently of each other, an alkylene, an arylene or -CH2-CH2-(O-CH2-CH2)m-, wherein m is an integer of 1 or more, and the alkylene, arylene and -CH2-CH2-(O-CH2-CH2)m- are optionally substituted by one or more halogen atoms. The polymers of the invention can be used as battery electrolytes.
