A Novel cathode material based on polyaniline used for lithium/sulfur secondary battery
چکیده انگلیسی

Polyaniline polysulfide (SPAn) was prepared for high energy secondary lithium batteries as cathode material. Polyaniline was synthesized via a classical chemical oxidation way, and then HCl was used to substitute the H atoms on the 6 member rings, so that polyaniline chloride (CPAn) was gained. The SPAn was prepared by way of substitute the Cl atoms on the aromatic rings of CPAn by S atoms in assistant of Na2S and element sulfur. Element analysis tests proved that there are more than 7 S atoms on each aniline structural group. FT-IR, Raman and XPS (X-ray photoelectron spectroscopy) analysis were used to confirm the SPAn's configuration. Button type battery was assembled, and charge–discharge test shows an initial discharge capacity of more than 980 mAh g−1, which is a grafting value.
