Abstract
We have synthesized a perylene-based aromatic polyimide (PI) through the polycondensation of perylene dianhydride with a 2,6-DAAQ. The battery cells with the PI cathode exhibited high discharge capacities of 209 mA h g<sup>−1</sup> (Li<sup>+</sup>/Li) and 207 mA h g<sup>−1</sup> (Na<sup>+</sup>/Na) at 200 mA g<sup>−1</sup>.
