A method for manufacturing a secondary battery includes a forming step of pressing a pouch sheet by using a press die so that left and right accommodation grooves, which are bilaterally symmetrical to each other and are opened upward, and a bridge connecting the left and right accommodation grooves to each other are formed in the pouch sheet, wherein the bridge protrudes upward with respect to bottom surfaces of the left and right accommodation grooves, and a curved portion having a rounded shape is formed on an upper end of the bridge, a seating step of seating an electrode assembly in one of the left and right accommodation grooves, and a folding step of folding the pouch sheet so that the left and right accommodation grooves face each other.

A method of making a tube (60) includes forming at least one tube layer (101, 106, 108); and forming at least one film layer (102, 103, 104) on the at least one tube layer, wherein the at least a portion of the at least one film layer does not completely overlap the at least one tube layer.

A method for processing a fluid with forward osmosis process includes providing one or more tubular membranes each including a tubular nonwoven base layer on the outside of the tubular membrane forming an outer shell of the tubular membrane and providing a lumen for feed flow; a polymer substrate layer on the lumen-side of the tubular membrane comprising three regions, including a region where the polymer substrate layer is partially intruded into the tubular base layer, a region with an open macrovoid structure and a region with an asymmetrical foamy layer, where the partially intruded region forms an intermediate layer; and a functional top layer on the polymer substrate layer. The tubular base layer comprises a longitudinal weld. The method includes providing the feed flow through the lumen and providing a draw solution on the outer shell side of the tubular membrane; and processing the feed flow with the membrane.

The present disclosure relates to liners and methods of making liners. The liners may be suitable for use with tanks and other storage/containment vessels, such as process tanks, immersion tanks, indoor or outdoor containment pits, gravity feed conduits (e.g., concrete trench, canal, or drain, etc.) for transferring or conveying liquid, grain storage tanks or containers (e.g., dielectric or electrically non-conductive liners for grain storage, etc.), etc.

Inflatable medical devices and methods for making and using the same are disclosed. The devices can be medical invasive balloons, such as those used for transcutaneous heart valve implantation, such as balloons used for transcatheter aortic-valve implantation. The balloons can have high strength, fiber-reinforced walls.
