Abstract

Nitrogen-doped carbon materials have been prepared by soap-free emulsion with poly(acrylonitrile) (PAN) and poly(acrylonitrile)-ionic liquid copolymer (PAN-PIL) as carbon sources. The carbonized PAN-PIL (CPAN-PIL) shows a higher nitrogen content (6.80 at.%.) than the carbonized PAN (CPAN) (2.32 at.%). The ionic liquid copolymer introduced graphitic nitrogen to CPAN-PIL, which was not observed in CPAN. The high nitrogen content and graphic nitrogen improved the electrical conductivity and increased the number of active sites. Therefore, CPAN-PIL displayed a specific capacity of 381 mAh g^-1 after 50 cycles, which is 23% higher than the specific capacity of CPAN.
