Abstract

본 발명은 다공성 폴리술폰막에 프로필렌카보네이트 및 리튬 퍼클로레이트의 액체 전해질을 담지시킨 고체 고분자 전해질 및 그의 제조방법에 관한 것이다. 본 발명의 고체 고분자 전해질은 우수한 기계적 물성을 지니는 폴리술폰막을 사용하므로 그의 동공 내에 다량의 액체 전해질을 함유할 수 있으며, 다량으로 함유된 프로필렌 카보네이트는 상기 고분자 전해질의 이온 전도도를 증가시킨다. 또한, 상술한 고체 고분자 전해질의 제조방법은 종래의 제조방법에서 사용된 자외선 등의 조사공정 및 다공성 막과 액체 전해질과의 상용성을 개선키 위한 동공 코팅공정을 필요치 않으므로, 제조공정이 간단하고 경제적인 방법이다. 따라서, 본 발명의 고체 고분자 전해질은 리튬 고분자 이차전지를 비롯한 여러 전기 화학장치에 유용하게 사용될 수 있다.The present invention relates to a solid polymer electrolyte in which a liquid electrolyte of propylene carbonate and lithium perchlorate is supported on a porous polysulfone membrane, and a method of manufacturing the same. Since the solid polymer electrolyte of the present invention uses a polysulfone membrane having excellent mechanical properties, it can contain a large amount of liquid electrolyte in its pupil, and the propylene carbonate contained in a large amount increases the ionic conductivity of the polymer electrolyte. In addition, the manufacturing method of the above-mentioned solid polymer electrolyte does not require the irradiation process such as ultraviolet rays used in the conventional manufacturing method and the pupil coating process to improve the compatibility between the porous membrane and the liquid electrolyte, so that the manufacturing process is simple and economical. It's how it is. Therefore, the solid polymer electrolyte of the present invention can be usefully used in various electrochemical devices including lithium polymer secondary batteries.
