| 제목 | Effect of Molecular Weight on ionic conductivities of Chemical Gel Polymer Electrolyte Based on (PEO)n(MA)y |
| 초록 | In this work, a series of gel type polymer electrolytes based on (PEO)n(MA)y has been prepared and the effects of their molecular structures on ionic conductivities of the obtained gel electrolytes were investigated. Liquid electrolyte composed of EC : EMC : PC : DEC (20 : 60 :10: 10) was mixed with a small amount of gel forming monomer, (PEO)n(MA)y. Final electrolyte formulation consisted of 1.15M LiPF6 in EC : EMC : PC : DEC (20 : 60 :10: 10). Lauryl peroxide was used as a thermal initiator. Electrolyte was then polymerized by a thermal reaction at 80 oC for 90 min. Gel was attainable well as PEO chain length was short. but ionic conductivities was high when PEO chain length was long. |
