Organic cathode material for high-capacity Li-ion battery with fast charge and discharge

Versatility of chemical structures is a benefit of functional materials based on organic molecules. Although there are various types of redox-active functional groups, it is preferable to choose those consisting of atoms in the second row of the periodic table because of their low atomic weights, availability, and sustainability. Thus, we focus on molecules that consist of hydrogen, carbon, nitrogen, and oxygen, and we found that the polymer (polymethacrylate) bearing pyrene-4,5,9,10-tetraone (PYT) as a redox-active core exhibited remarkable charge−discharge properties as a cathode material in a Li-ion battery.
