碩士 === 國立中正大學 === 光機電整合工程所 === 96 === A new organic/inorganic hybrid soft battery system has been developed. Conducting polymer (poly-pyrrole (PPy) or poly-aniline (PAn)) and buckminster fullerene (C60) are used as the cathode and anode material, respectively. The conducting porous polymer electrolytes comprise the main materials including poly(vinylidene fluoride-co-hexafluo ropropylene) (PVDF-HFP), ethylene carbonate (EC), dimethyl carbonate (DMC), and LiPF6. Comparing the oxidation potential of PPy and PAn soft batteries, it is conducted that PAn possesses a larger open-circuit potential (1.5 V) then that in PPy (1 V). However, from the charging and discharging curves measurements, it was found PPy has a longer stable useable output voltage than that in PAn. Finally both PPy and PAn soft batteries were measurement to possess a common drawback (ie. a weak resistance ability to avoid the penetration of water and oxygen from the air of environment). Further work is needed in this direction.
