Preparation and Properties of Polytriphenylamine/Multi-Walled Carbon Nanotube Composite as a Cathode Material for Li-Ion Batteries

A composite of polytriphenylamine (PTPAn) and multiwalled carbon nanotube (CNT) was prepared and tested as a cathode material in the Li-ion battery. To research the crucial role and effect of CNT in the above composite electrode, a comparing cathode of PTPAn mechanically mixed with super-p carbon was prepared and tested in the similar Li-ion batteries. The results indicate that due to good resiliency and loosing structure of the composite, PTPAn/CNT composite cathode exhibits lower charge transfer resistance (R ct ), higher discharge capacity and cycle stability than those of PTPAn+super-p electrode.
