Abstract: There is a method for monitoring emotion and behavior occurring during a conversation with a user who is in need of protection. According to an embodiment, a user monitoring method receives an input of a user utterance and generates a conversation content by using a conversation model based on a user utterance content, converts the generated conversation content into a voice and outputs the voice, and recognizes emotion of the user by using an emotion analysis model based on the user utterance content and monitors the emotion. Accordingly, the method may monitor behavior/emotion of a user through a natural conversation while allowing a specialist/guardian to monitor an abnormal sign of a user who is in need of protection.

Abstract: A separator for a lithium secondary battery. The separator for a lithium secondary battery is provided with a porous coating layer including small-particle diameter inorganic particles, large-particle diameter inorganic particles and adhesive polymer particles. The porous coating layer has a predetermined level of porosity. The separator has reinforced heat resistance, reduced resistance and improved peel strength to a porous polymer substrate.

Abstract: A separator for an electrochemical device including a porous separator substrate including a polymer material, and a porous coating layer coated on at least one surface of the porous separator substrate. The porous coating layer includes inorganic particles and a binder resin. The binder resin includes a mixture of polyvinyl acetate (PVAc) with an acrylic binder resin. The separator has improved wettability with an electrolyte by virtue of relatively high polarity of PVAc. In addition, it is possible to improve the peel force between the separator substrate and the porous coating layer by introducing PVAc and to reduce the thickness of the porous coating layer. Therefore, when introducing the separator to a battery, it is possible to improve the resistance characteristics, and to inhibit the porous coating layer from being spaced apart from the separator substrate or to inhibit the inorganic particles from being detached from the porous coating layer.

Abstract: The present invention relates to a safety-improved battery cell including a thermal expansion tape and a method of manufacturing the same, wherein a battery pack including multiple battery cells is configured such that heat generated during a charging/discharging process and internal gas generated thereby are discharged to outside of a battery cell by employing a thermal expansion tape. Thus, the present invention can improve safety of a pouch-type secondary battery pack by discharging gas generated in a pouch-type secondary battery. In addition, the present invention utilizes pressure of gas generated in the secondary battery and thus can be operable without provision of a separate device and an external power source. Moreover, the present invention can perform repetitive gas discharge due to a configuration of a fixing unit having thermal expansion properties.
