POLYMER ELECTROLYTE AND METHOD OF MANUFACTURING THE SAME

摘要

Disclosed are a polymer electrolyte having a good mechanical strength and adhesiveness and a method of manufacturing thereof. First, a polyvinylidene fluoride-based polymer and an electrolytic solvent in which an electrolytic salt is dissolved are mixed in a mixing ratio of about 1:2-10 by weight. Then, a substantially homogeneous electrolytic slurry is prepared by stirring and heating thus obtained mixture. After that, thus obtained electrolytic slurry is solidified to manufacture the polymer electrolyte. The polymer electrolyte has a good mechanical strength and illustrates a good adhesiveness to an electrode. A lithium secondary battery employing the polymer electrolyte illustrates a stable charge/discharge characteristic and a high capacitance.
