A polyimide derivative containing different carbonyl groups for flexible lithium ion batteries

Author affiliations

Abstract

A novel polyimide derivative is prepared by a condensation polymerization of pyromellitic dianhydride and 2,6-diaminoanthraquinone and a flexible electrode film –SWNT is further fabricated by filtration with single-walled carbon nanotube dispersions. connects different carbonyl groups of dianhydride and quinone together, therefore combining the advantages of different units together. Electrochemical tests show that –SWNT can transfer three electrons reversibly and theoretical calculations also prove that. –SWNT shows a high capacity of 190 mA h g−1 and superior rate performance, maintaining 120 mA h g−1 at 20C. –SWNT is a promising flexible electrode because of its good performance and flexibility.
