METHOD FOR MANUFACTURING SEPARATOR AND SEPARATOR MANUFACTURED THEREBY
세퍼레이터의 제조방법 및 이에 의해 제조된 세퍼레이터
Abstracts:
The present invention relates to a method for manufacturing a separator and a separator manufactured thereby, and is characterized in that a porous coating layer is formed by using a slurry for forming a porous coating layer, comprising inorganic particles, lithium halide, and a polyvinylidene fluoride-based binder polymer. According to the above-mentioned characteristic, a separator having lower resistance and an electrochemical element comprising the same may be provided by changing the characteristics of the binder polymer.
본 발명은 세퍼레이터의 제조방법 및 이에 의해 제조된 세퍼레이터에 관한 것으로서, 무기물 입자, 리튬 할라이드, 폴리비닐리덴 플루오라이드계 바인더 고분자를 포함하는 다공성 코팅층 형성용 슬러리를 이용하여 다공성 코팅층을 형성하는 데에 발명의 특징이 있다. 상기와 같은 특징으로 인하여 바인더 고분자의 특성을 변경함으로써, 저항이 보다 낮은 세퍼레이터 및 이를 포함하는 전기화학소자를 제공할 수 있다.

Titles:
Ceramic coating diaphragm for lithium-containing electrochemical battery and manufacturing method thereof
用于含锂电化学电池的陶瓷涂覆隔膜及其制造方法
Abstracts:
The invention discloses a ceramic coating diaphragm for a lithium-containing electrochemical battery and a manufacturing method thereof. Provided are a ceramic coated separator for a lithium-containing electrochemical battery and a method for preparing the ceramic coated separator. The ceramic-coated separator can be manufactured by preparing a slurry containing one or more lithiated oxides and a binder and disposing the slurry on one or more surfaces of a porous substrate. The slurry may be dried to form a ceramic coating on one or more surfaces of the porous substrate, thereby producing a ceramic coated separator. The ceramic coating may include one or more lithiated oxides selected from Li2SiO3, LiAlO2, Li2TiO3, LiNbO3, Li3PO4, Li2CrO4 and Li2Cr2O7.
