CONDUCTING PLOYMER NANOFIBERS AS CATHODE FOR HIGH-PERFORMANCE LITHIUM–AIR CELLS
High-quality polyaniline nanofibers with average diameter of 100nm were formed using a chemical route--aqueous/organic interfacial polymerization without any templates under the ambient conditions. The SEM images showed that the nanofibers agglomerated into a network. The FT-IR spectra of the purified nanofibers, with the absorption peak centered around 1580cm-1 and 1500cm-1, showed that they were in emeraldine oxidization, which had the highest electronic conductivity in all oxidation of polyaniline. When the prepared polyaniline were used as catalyst support in the air electrode, and electrolytic manganese dioxide as catalyst, PVDF as binder, the capacity of lithium-oxygen (air) cell was significantly improved over the common carbon supports. The specific capacity as high as 450mAh g-1 at a high rate of 0.5 mA cm-2, may pave a new road for the development of the lithium-oxygen (air) cells.
