Polydiaminoanthraquinones with tunable redox properties as high performance organic cathodes for K-ion batteries.

Polydiaminoanthraquinones, featured as redox-active quinone segments linked by polyaniline, were investigated as novel organic cathodes for K-ion batteries. With electron-withdrawing groups (CN) substituted, elevations of the redox potential and capacity utilization were achieved. [ABSTRACT FROM AUTHOR]
