Encapsulation system for electronic components and batteries
Systems, methods, and apparatus for encapsulating objects like that of microelectronic components and batteries. The system includes three successive layers that include a first covering layer composed of an electrically insulating material deposited by atomic layer deposition, which at least partly covers the object, a second covering layer that includes parylene and/or polyimide, and which is disposed on the first covering layer, and a third covering layer deposited on the second covering layer in such a way as to protect the second encapsulation layer, namely, with respect to oxygen, and thereby increase the service life of the object.
ELECTRIC CELL POTTING COMPOUND AND METHOD OF MAKING
A battery module comprising an electric cell and a potting compound associated with the electric cell. The potting compound is formed of a flame retardant component; a first component having an isocyanate reactive compound and water; and a second component having an isocyanate compound. The potting compound is a foam.
Pouch Cell Cutting Apparatus and Pouch Cell Manufacturing Method
A pouch cell cutting apparatus according to an embodiment of the present disclosure, includes a top knife and a bottom knife for cutting a sealing part of a battery cell which includes a cell case and an electrode assembly housed in the cell case, wherein both side parts of the top knife comprises protrusion parts protruding toward the recessed parts formed on both side parts of the bottom knife, respectively, and wherein a corner part of the battery cell is cut by the protrusion part.
Thin aerogel materials
The present invention provides a fiber-reinforced aerogel material which can be used as insulation in thermal battery applications. The fiber-reinforced aerogel material is highly durable, flexible, and has a thermal performance that exceeds the insulation materials currently used in thermal battery applications.

Secondary battery
Various embodiments of the present invention relate to a secondary battery. The technical problem to be solved is to provide the secondary battery which can improve the insulation strength of first and second multi-tabs, by forming the first and second multi-tabs of first and second electrode assemblies symmetrically with respect to each other, and also can improve the insulation strength of the first and second multi-tabs by forming an insulating layer on the first and second multi-tabs of the first and second electrode assemblies. To this end, disclosed is a secondary battery comprising a case; a first electrode assembly which is housed inside of the case and has a first multi-tab; a second assembly which is housed side by side with the first electrode assembly on the inside of the case and has a second multi-tab; and a cap plate which blocks the case and has an electrode terminal electrically connected to the first and second multi-tabs of the first and second electrode assemblies, wherein the first and second multi-tabs are formed symmetrically to each other with respect to a mutual boundary region of the first and second electrode assemblies, and an insulating layer is coated on the surface of the first and second multi-tabs.
Outer case for flexible rechargeable battery and flexible rechargeable battery including same
The present disclosure relates to an outer case for a flexible rechargeable battery, including a first resin layer configured to include a first patterned area, a moisture barrier layer disposed on the first resin layer to include a second patterned area, a second resin layer disposed on the moisture barrier layer to include a third patterned area, and a stress relaxation layer configured to cover the third patterned area.
Secondary battery comprising the opening
In the case where a film, which has lower strength than a metal can, is used as an exterior body of a secondary battery, a current collector provided in a region surrounded by the exterior body, an active material layer provided on a surface of the current collector, or the like might be damaged when force is externally applied to the secondary battery. A secondary battery which is resistant to external force is obtained. An opening is provided in a central portion of the secondary battery; and a terminal is formed in the opening. An outer edge of the secondary battery is fixed by thermocompression bonding. In addition, the central portion of the secondary battery is fixed by thermocompression bonding, so that the amount of bending is limited even when the outer edge portion of the secondary battery is bent.
