Abstract:
A battery module includes a battery cell stack having a plurality of battery cells or unit modules connected in series and/or in parallel to each other in a state in which the battery cells or the unit modules are stacked in the lateral direction. The battery cell stack is provided at the front thereof with bus bars to connect electrode terminals of the battery cells to external input and output terminals. Voltage sensing members are provided at ends thereof with connection terminals electrically connected to electrode terminal connection parts of the battery cells to sense voltages of the battery cells or the unit modules. An upper case is provided with mounting parts, in which the voltage sensing members are mounted. A lower case is coupled to the upper. The lower case is provided at the front thereof with external input and output terminals.
Abstract:
Disclosed are a fiberweb, a preparation method thereof, and a filter including the fiberweb. The fiberweb includes a wholly aromatic liquid crystal polyester resin which includes a repeating unit induced from a hydroxybenzoic acid and a repeating unit induced from a hydroxynaphthoic acid, but does not include a repeating unit induced from an aromatic dicarboxylic acid.

Abstract:
Methods of preparing an aromatic liquid crystalline polyester resin and an aromatic liquid crystalline polyester resin compound are disclosed. A method of preparing an aromatic liquid crystalline polyester resin may include: acetylating a first monomer including an amino group by a reaction with a carboxylic acid anhydride; acetylating a second monomer including a hydroxyl group and not including an amino acid group with an additional carboxylic acid anhydride; and synthesizing an aromatic liquid crystalline polyester prepolymer by a condensation polymerization reaction of the acetylated first and second monomers with dicarboxylic acid. A method of preparing an aromatic liquid crystalline polyester resin compound may use the aromatic liquid crystalline polyester resin prepared according to the forgoing method.

Abstract:
Disclosed herein is a high-power, large-capacity battery module including a plurality of battery cells or unit modules connected in series to each other such that the battery cells or the unit modules are stacked while being in tight contact with each other or being adjacent to each other, wherein the battery module is fixed such that the stacked state of the battery cells or the unit modules is maintained even when the volume of the battery cells or the unit modules changes at the time of charging and discharging the battery cells or the unit modules, and a portion of an electrode terminal connection region between the battery cells or between the unit modules is weak with respect to the volume expansion of the battery cells or the unit modules such that an expansion stress caused by the swelling of the battery cells is concentrated on the electrode terminal connection region, whereby the electrode terminal connection region is broken, and therefore, an electrical cut-off occurs at the electrode terminal connection region, when the swelling exceeds a predetermined value.
Abstract:
A magnetic nanoparticle complex includes a magnetic nanoparticle; and a ligand associated with the magnetic nanoparticle, the ligand including a functional group capable of combining with an acid component or a conjugate base of the acid component, in an oil. A method for preparing a magnetic nanopartide complex, includes preparing a pre-ligand having at least one amino group and at least one carbamate group or dithiocarbamate group; associating the pre-ligand with a magnetic nanoparticle to form a magnetic nanoparticle-ligand complex; and modifying the ligand to form a modified ligand having a functional group capable of combining with an acid component in an oil or a conjugate base of the acid component.
