Nitrogen doping of tubular hard carbon as conjugate microporous polymer and its lithium storage performance

Abstract

Abstract: Conjugate microporous polymer (CMP) and nitrogen-contained conjugate microporous polymer (NCMP) were synthesized with chosen different monomers and the tubular hard carbon(THC) and N-doped tubular hard carbon(NTHC) were prepared by means of pyrolysis of those two kinds of CMP. The morphology and structure of the two tubular hard carbons were characterized with SEM, TEM and BET and it is shown that the materials of THC and NTHC have similar morphology and specific surface area. Further, The electrochemical property of THC and NTHC then compared with that of common carbon nanotube(CNT) was analyzed by constant current charge and discharge method and the result showed that the lithium storage performance of NTHC would be the best and it would have a high reversible lithium storage capacity of 541.2 mAh/g at 0.1 A/g and its specific capacity would retain around 458 mAh/g at 0.6 A/g after 500 cycles.
