The present disclosure discloses a cell module assembly receiving structure including: a cell module assembly comprising a plurality of cells; and a receiving device having an inner space capable of receiving the cell module assembly, wherein the receiving device includes a first partition wall disposed to extend from a first wall in a direction toward a second wall facing the first wall and a second partition wall disposed to extend from the second wall in a direction toward the first wall, wherein a sum of an extension length of the first partition wall and an extension length of the second partition wall is greater than or equal to a distance between the first wall and the second wall.

Cell module assembly receiving structure having improved safety

A battery pack which may secure safety when fire or gas occurs therein or when an external impact is applied thereto is provided. The battery pack includes: a cell assembly including a plurality of secondary batteries; and a pack case including a bottom part having a plate shape and located under the cell assembly, and a side wall part protruding from the bottom part to a preset height, the pack case accommodating the cell assembly in an inner space defined by the bottom part and the side wall part, wherein the side wall part of the pack case includes a hollow in a direction at least partially perpendicular to a thickness direction of the side wall part, and the hollow includes an inwardly open inlet and an outwardly open outlet.

Battery pack

Provided is a separator for an electrochemical device including a plate-like porous substrate, and a porous thin-film coating layer formed on at least one surface of the plate-like porous substrate and containing crosslinked polyester. The crosslinked polyester coating layer hardly affects the air permeability of the separator. Also, the crosslinked polyester coating layer has good hydrophilicity and wettability to an electrolyte, and thus improves the performance of the battery. Also, the crosslinked polyester coating layer has excellent resistance to heat and deformation, and thus prevents the thermal shrinkage of the separator.

The present invention relates to a composition for preparing an excellent protecting film with high strength, wear resistance, and excellent barrier property by low temperature hardening, a protecting film prepared therefrom, a substrate comprising the same, and a component or device comprising the same. The composition comprises an organosiloxane polymer a), a photobase generator b), and an organic solvent c).

At low temperature, fast hardening composition for preparing protecting film, protecting film prepared therefrom, and substrate comprising the same

The present invention relates to a coating composition for a film with low refractive index and a film prepared therefrom, and more precisely, a coating composition with low refractive index which contains dispersed porous organic/inorganic hybrid nano-particles or a colloid containing the dispersed nano-particles, a photocurable compound having unsaturated functional groups, photoinitiator or photosensitizer, or an organic siloxane thermosetting compound, and a solvent and a film prepared therefrom. According to the present invention, porous particles have been formed by using a structural regulator in a silane compound at a specific size, in order to be fitted for a film with low refractive index, and then the structural regulator has been eliminated by a simple process before forming the film, resulting in preparation of a film with extremely low refractive index at a low temperature of up to 120&#xb0; C. which will be applied as a film with low refractive index or a film with low reflection for various uses including displays.

Coating composition for film with low refractive index and film prepared therefrom

The present invention relates to a coating composition for a dielectric insulating film comprising a) an organosiloxane polymer, b) first metal ions selected from the group consisting of Rb ions, Cs ions, and a mixture thereof, and c) an organic solvent, in which the first metal ions are comprised at 1 to 200 ppm based on the weight of the composition, a dielectric insulating film prepared therefrom, and an electric or electronic device comprising the same. A dielectric insulating film prepared from the coating composition of the present invention has an improved dielectric constant and superior mechanical strength and electric properties.
