Device and method for bonding fuel cell part
A bonding device of a fuel cell part is disclosed. The bonding device of the fuel cell part may bond an upper gas diffusion layer and a lower gas diffusion layer to top and bottom surfaces of an MEA base material through adhesive layers, while disposing the MEA base material between the upper gas diffusion layer and the lower gas diffusion layer, and may include: a lower die that supports the MEA base material, the upper gas diffusion layer, and the lower gas diffusion layer to be bonded with each other; an upper die installed in an upper side of the lower die; and an ultrasonic wave vibration source that is installed to be capable of moving in a vertical direction at opposite sides of the upper die, compressing the upper gas diffusion layer, and applying ultrasonic wave vibration energy to the adhesive layer.
Battery Case Shaping Apparatus and Battery Case Manufacturing Method Using the Same
A battery case shaping apparatus includes a punch, a die, a holder, and an elastic separator. The punch is configured to press a laminate sheet into a shape of an electrode assembly receiving portion. The die has formed therein an accommodation portion having a size corresponding to the electrode assembly receiving portion. The holder is configured to fix the an outer periphery of the laminate sheet. The elastic separator is located under the punch in order to prevent direct contact between the punch and the laminate sheet. A battery case manufacturing process uses the battery case shaping apparatus to manufacture a battery case.
SONOTRODE FOR THE ULTRASONIC WELDING OF PLASTIC COMPONENTS OF AN ELECTRONIC CIGARETTE
The invention relates to a sonotrode for the ultrasonic welding of plastic components of an electronic cigarette.
The sonotrode comprises: a body comprising a first end which can be connected to an ultrasound generator, and a second end; a cavity that develops from the second end towards the first end, for receiving at least partially a plastic component of an electronic cigarette to be welded. The cavity defines an opening at the second end of the body, communicating with the outside of the sonotrode.
In particular, at the opening, the cross section of the cavity has an outline comprising: a first portion that has the shape of a first arc of a reference circumference, which comprises a first end and a second end, opposite each other; and a second portion, that has the shape of a second arc of said reference circumference, which comprises a first end and a second end, opposite each other.
The aforementioned outline further comprises: a third portion, connected to the first end of the first portion and to the first end of the second portion, which develops externally with respect to the reference circumference; and a fourth portion, connected to the second end of the first portion and to the second end of the second portion, which develops externally with respect to said reference circumference.
Cross-linked polyolefin separator and manufacturing method thereof

Multimaterial 3d-printing with functional fiber
In a method for printing a three dimensional structure, a continuous length of fiber that includes, interior to a surface of the fiber, a plurality of different materials arranged as an in-fiber functional domain, with at least two electrical conductors disposed in the functional domain in electrical contact with at least one functional domain material, is dispensed through a single heated nozzle. After sections of the length of fiber are dispensed from the heated nozzle, the sections are fused together in an arrangement of a three dimensional structure. The structure can thereby include a continuous length of fiber of least three different materials arranged as an in-fiber functional device, with the continuous length of fiber disposed as a plurality of fiber sections that are each in a state of material fusion with another fiber section in a spatial arrangement of the structure.
NANOPOROUS COMPOSITE SEPARATORS WITH INCREASED THERMAL CONDUCTIVITY
Nanoporous composite separators are disclosed for use in batteries and capacitors comprising a nanoporous inorganic material and an organic polymer material. The inorganic material may comprise Al.sub.2O.sub.3, AlO(OH) or boehmite, AlN, BN, SiN, ZnO, ZrO.sub.2, SiO.sub.2, or combinations thereof. The nanoporous composite separator may have a porosity of between 35-50%. The average pore size of the nanoporous composite separator may be between 10-90 nm. The separator may be formed by coating a substrate with a dispersion including the inorganic material, organic material, and a solvent.
