Abstract
The composite film of polyaniline containing a complex of poly(ethylene oxide) (PEO) and lithium perchlorate was prepared and used as a positive in solid-state lithium rechargeable battery. The charge and discharge behaviour at constant current density of 0.1 and 0.2 mA/cm 2, recycleability and the rate of self-discharge were measured at room temperature. The preliminary results showed that the composite positive of polyaniline exhibited a good compatibility with polymer solid-state electrolyte and its service life was up to 250 cycles at deep charge/discharge between 2.5 and 4.0 V. The coulombic efficiency and the capacity density of the Li/PAN solid-state rechargeable battery were 98% and 48.3 A h/kg, respectively (based only on positive active material).
