Abstract

Herein we report the development of nanostructured poly(1,4-dihydro-11H-pyrazino[2′,3′:3,4]cyclopenta[1,2-b]quinoxalin-11-one) (PPCQ), a novel conjugated ladderlike oligomer with the presence of a rich amount of heteroatoms, as the anode material. Beyond its remarkable lithium storage of 972 mAh g-1 after 120 cycles, the superior cycle life and stable capacity performance of 489 mAh g-1 revealed by ultralong testing of 1000 cycles (with an average Coulombic efficiency 99.8%) at a high current density of 2.5 A g-1 indicate its excellent electrochemical stability to be promisingly applied for high-performance lithium-ion batteries (LIBs).
