The solid polymer electrolytes(SPEs) are flexible and have inhibition of lithium dendrite growth. However, the ionic conductivity has not apply to reach the high level. For the reason The researchers have used plasticizer such as carbonate series to obtain enhanced higher ionic conductivities. In this study, PEG-borate ester as a new type of plasticizer with excellent thermal stability, high flash point and good fludity even at low temperature was used Among several polymer electrolyte system, poly (ethylene glycol) has shown great potential as the best solvating for a variety of lithium salts. PEG easily solvates cations by interaction with the polar ether oxygen in the main chain and can coordinate effectively with cations to form homogenous solutions. The hybrid matrix added with a plasticizer was analyzed by H-NMR, FT-IR, FE-SEM, TGA and EIS. 2017년 한국교통대학교 지원을 받아 수행하였음. |
