Abstract

According to the evidence from both theoretical calculations and experimental findings, conjugated ladder polymers containing large π-conjugated structure, a high number of nitrogen heteroatoms, and a multiring aromatic system, could be an ideal organic anode candidate for lithium-ion batteries (LIBs). In this report, we demonstrated that the nanostructured polyazaacene analogue poly(1,6-dihydropyrazino[2,3g]quinoxaline-2,3,8-triyl-7-(2H)-ylidene-7,8-dimethylidene) (PQL) shows high performance as anode materials in LIBs: high capacity (1750 mAhg-1, 0.05C), good rate performance (303 mAhg-1, 5C), and excellent cycle life (1000 cycles), especially at high temperature of 50°C. Our results suggest nanostructured conjugated ladder polymers could be alternative electrode materials for the practical application of LIBs.
