The present disclosure relates to a preparation method of a super absorbent polymer. More specifically, it relates to a preparation method of a super absorbent polymer capable of significantly reducing the amount of fine powder generated during the process by mixing a hydrogel polymer with an additive having a specific structure, pulverizing it, and then drying it with a paddle-type dryer.

Preparation method of super absorbent polymer

Disclosed is a battery pack having a structure in which a plurality of unit cells constitutes a battery module, two or more of the battery modules are vertically arranged from a coolant introduction direction of a coolant inlet port to constitute a pair of battery module groups, a coolant introduction part extending from the coolant inlet port to each battery module group is provided at a middle of a pack case wherein the coolant introduction part is located between respective battery module groups, coolant discharge parts extending from respective battery module groups to coolant outlet ports are provided at an upper and lower part of the pack, and a coolant flow channel defined between the coolant introduction part and the coolant discharge parts is configured such that a coolant, introduced through the coolant introduction part, passes by each unit cell, and is discharged through the respective coolant discharge parts.

Battery pack of novel air cooling structure

A battery pack including battery cells or unit modules (unit cells), configured to have a structure including a battery module group including one or more battery modules each having the unit cells mounted in a pack case in a state in which the unit cells are uprightly arranged in a width direction of the pack such that the unit cells are spaced apart by a spacing distance for coolant flow, a coolant introduction part continuously defined in a space between a bottom of the pack case and the battery module group, a coolant discharge part defined between a top of the pack case and the battery module group, an electronic member located at one side of the module group, the electronic member being mounted in an inner space defined by the coolant discharge part, and a coolant flow channel defined between the coolant introduction part and the coolant discharge part.

Battery pack having novel cooling structure

A dipping bath according to the present disclosure includes a body to hold a slurry for dip coating, an inlet installed to flow the slurry from an outside of the body to an inside, and an outlet installed to discharge the slurry from the inside of the body to the outside, and one end of the inlet placed inside the body may be disposed facing a side surface of the body at a distance and may be tilted to a predetermined angle in a direction toward a bottom surface of the body. According to the present disclosure, adjustment of an incidence angle of the slurry flowing into the bath through the inlet may increase a flow rate of the slurry toward the bottom surface, as well as allowing a uniform distribution of solids contained in the slurry circulating through the bath.

Dipping bath

Disclosed is a battery pack including battery cells or unit modules (unit cells), wherein the battery pack is configured to have a structure in which the unit cells are uprightly arranged in a width direction (a horizontal direction) of the battery pack in a state in which a spacing distance for coolant flow is provided between the respective unit cells to constitute a battery module, a plurality of battery modules is arranged to constitute a battery module group, battery modules groups are vertically arranged from a coolant introduction direction of a coolant inlet port in a height direction (a vertical direction) of the battery pack to have a two or more layer structure or laterally arranged from the coolant introduction direction of the coolant inlet port in a length direction (a horizontal direction) of the battery pack to have a two or more row structure.

Battery pack providing improved distribution uniformity in coolant

Disclosed herein is a plate-shaped secondary battery configured to have a structure in which an electrode assembly of a cathode/separator/anode structure is mounted in a battery case in a sealed state by thermal welding, wherein a protuberance is formed at an outer edge sealed portion of an electrode assembly receiving part of the battery case such that the protuberance protrudes upward and downward from the sealed portion, and the protuberance extends along the outer edge of the electrode assembly receiving part continuously in a curved line or in a straight line in a state in which the protuberance is adjacent to the electrode assembly receiving part.

Secondary battery of novel structure

Disclosed herein is a battery pack having a plurality of battery cells or unit modules ('unit cells') electrically connected to each other, wherein the unit cells are arranged in a width direction (traverse direction) of the battery pack in an upright fashion in a state in which the unit cells are spaced apart from each other to form coolant flow channels, thereby constituting a battery module layer, and two or more battery module layers are mounted in a pack case such that the battery module layers are stacked in a height direction (vertical direction) of the battery pack, and wherein the battery pack includes a coolant introduction part, through which a coolant is introduced into the two or more battery module layers to simultaneously cool some or all of the unit cells in the two or more battery module layers, and a coolant discharge part, through which the coolant, having passed the unit cells, is discharged.
