제목 Characterization of 3-layer composite film for lithium-ion pouch cells
초록 The lithium-ion battery consist of cathode, anode, separator, electrolyte and packaging material to protect it. There are a cylindrical type and a pouch type in a packaging material. The pouch type packaging materials for lithium-ion batteries are used in medium-sized batteries such as electric vehicles, energy storage devices and small-sized batteries for mobile phones. In general, this packaging material is divided into an outer film layer and an inner sealant layer around a barrier layer. In the case of sealant materials, polyolefin such as polyethylene (PE) or polypropylene (PP) are mainly used. In industry, when LiPF6 salt is contacted with external moisture, HF is generated and permeates sealant layer and battery failure comes out. In this study, the orientation of surface treated h-BN in the PP matrix was controlled and 3-layer composite film with water vapor barrier function was fabricated and evaluated.
