Abstract
A copolymer of 4-(1H-pyrrol-1-yl)phenol (PLPY) and pyrrole ( P(PLPY-co-Py) )was synthesized. And the chemical structure and battery performance of the prepared materials were characterized comparably by 1H NMR, FT-IR spectra and galvanostatic charge-discharge testing using simulant lithium ion half-cell method, respectively. The results shows that the introduction of the phenol group to the pyrrole as a rigid side chain could prevent the polymer from agglomeration and optimize the particle morphology of the resulting polymers, all of which made it demonstrate a significantly improved specific capacity (73.9 mAh•g-1) compared with PPy (21.4 mAh•g-1)
