POLYPHENYLENE-BASED ANION CONDUCTOR, PREPARATION METHOD THEREFOR, AND USE THEREOF

WIPO Patent Application WO/2018/199545

A1

The present invention relates to a polyphenylene-based anion conductor, a preparation method therefor, and a use thereof. More specifically, the present invention relates to: a polyphenylene-based anion exchange material, wherein a polyphenylene-based anion exchange polymer has a lower crossover of an active material compared with the commercially available cation exchange material Nafion115, leading to excellent column efficiency and wherein, structurally, a main chain of the polymer is formed of polyphenylene and thus the main chain is composed of only C-C bonds between benzene rings without containing a linker group having an electron donor characteristic, such as -O-, -S-, or -(CH2)n-, leading to excellent material dimensional stability; a preparation method therefor; and a redox flow battery obtained by applying the prepared polyphenylene-based anion polymer to a separator for a redox flow battery.
