摘要：

The electrical properties of poly(3-methylthiophene) (P3MT) films synthesized by electrochemical polymerization and the discharge characteristics of secondary batteries utilizing P3MT film as the cathode-active material are described. The P3MT was synthesized in film forms by electrochemical polymerization in the propylene carbonate solutions containing LiBF4 or LiAsF6. The conductivity of the AsF6- doped [30 mole percent (m/o)] P3MT film prepared at 25°C was about 200 S/cm. A P3MT/LiBF4+PC+EC/Al (PC:propylene carbonate, EC:ethylene carbonate) battery was charged and discharged over 1200 cycles at the doping level of 9% while the coulombic efficiency maintained over 97%. The discharge characteristics are described in relation to the surface morphology of the films.
