Abstract: The present disclosure relates to a method for manufacturing an electrode assembly for an electrochemical device. More particularly, the present disclosure relates to a method for manufacturing a curved electrode assembly having a curve with a uniform curvature radius. According to the present disclosure, as the curved electrode assembly is manufactured by stacking a plurality of curved unit cells having a uniform curvature radius, restoration to the original shape is low and shape stability is high as compared to an electrode assembly manufactured by bending a flat electrode assembly. In addition, as unit cells included in an electrode assembly are produced to have a curve by a roll lamination process under a uniform condition and they have the same curvature radius or a small difference in curvature radius, it is possible to easily manufacture an electrode assembly having a desired curvature radius without excessive deformation of the unit cells.

Abstract: The present invention generally relates to microparticles and, in particular, to systems and methods for encapsulation within microparticles. In one aspect, the present invention is generally directed to microparticles containing entities therein, where the entities contain an agent that can be released from the microparticles, e.g., via diffusion. In some cases, the agent may be released from the microparticles without disruption of the microparticles. The entities may be, for instance, polymeric particles, hydrogel particles, droplets of fluid, etc. The entities may be contained within a fluid that is, in turn, encapsulated within the microparticle. The agent may be released from the entity into the fluid, and then from the fluid through the microparticle. In such fashion, the release of agent from the microparticle may be controlled, e.g., over relatively long time scales.

Abstract: The present invention generally relates to microfluidic droplets and, in particular, to multiple emulsion microfluidic droplets. In one set of embodiments, multiple emulsion droplets are provided, where an inner shell of the droplet is relatively thin, compared to the outer shell (or other shells) of the droplet.

Other embodiments of the present invention are generally directed to methods of making such droplets, methods of using such droplets, microfluidic devices for making such droplets, and the like.

Abstract: Disclosed is a method for manufacturing a secondary battery. More specifically, the present disclosure relates to a method for manufacturing an electrode assembly by stacking a plurality of bi-cell type and/or monocell type unit cells. A method for manufacturing an electrode assembly according to the present disclosure can easily remove the curvature which occurs in a unit cell in a roll lamination process, and fabricate a flat plate electrode assembly with a simple process. Further, when the electrode assembly is manufactured with the method described above, the curvature between the unit cells constituting the electrode assembly may be offset, and accordingly, a time during which the flat plate shape in the electrode assembly is maintained may be extended significantly.
