The synthesis and electrochemical performance of aniline based conducting polymers as cathode materials for lithium ion batteries

The PDTDA and P(2-ATP), which have polyaniline main chain and bonds structure, were easily polymerization by chemical oxidation method. Although doped polyaniline was not soluble, doped PDTDA and P(2-ATP) were soluble. The chemical structure of dedoped and doped PDTDA and P(2-ATP) was characterized...

More Information
Summary:The PDTDA and P(2-ATP), which have polyaniline main chain and bonds structure, were easily polymerization by chemical oxidation method. Although doped polyaniline was not soluble, doped PDTDA and P(2-ATP) were soluble. The chemical structure of dedoped and doped PDTDA and P(2-ATP) was characterized by FT-IR and XPS analysis. We studied the electrochemical performance such as the charge-discharge ability, discharge capacity, and cyclic voltammogram of them. The discharge capacities of PDTDA and P(2-ATP) after 50 th cycle were ~38 and ~37mAh/g. The discharge capacities of PDTDA and P(2-ATP) as a function different current after initial stabilized step were measured. Recovering rates after high C-rate at 0.1C are ~92 % (PDADT) and ~50 %(P(2-ATP).
