By a News Reporter-Staff News Editor at Journal of Engineering -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Kim, Dukjung (Yongin-si, KR); Kim, Taeahn (Yongin-si, KR), filed on December 23, 2014, was published online on April 11, 2017.
The assignee for this patent, patent number 9620747, is SAMSUNG SDI CO., LTD. (Yongin-si, Gyeonggi-do, KR).
Reporters obtained the following quote from the background information supplied by the inventors: "Embodiments relate to a secondary battery.
"Generally, secondary batteries can be discharged and recharged, unlike primary batteries, which are not rechargeable. Secondary batteries may be of a low capacity type, which includes battery cells in the form of a pack typically used for small portable electronic devices such as cellular phones and camcorders, or a high capacity type, which includes several battery cells connected to one another to be used as a motor-driving power source for electric scooters, hybrid vehicles, electric vehicles, etc.
"Secondary batteries may be manufactured in various shapes, such as cylindrical shape or prismatic shapes. A typical secondary battery may include an electrode assembly having a positive plate and a negative plate with a separator acting as an insulator between the positive and negative plates accommodated in a battery case with an electrolyte, and a cap assembly having electrode terminals coupled to the case. The electrode assembly may be connected to positive and negative terminals which protrude from the cap plate and may be exposed to the exterior of the secondary battery."
In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "Embodiments are directed to a secondary battery, including a case including an accommodating space therein, an electrode assembly in the accommodating space of the case, a collecting plate electrically connected to the electrode assembly, a cap plate sealing the case, the collecting plate passing through the cap plate, a terminal plate coupled to an exposed end of the collecting plate, and an insulation member between the cap plate and the terminal plate, the insulation member including a sealing member on at least one surface thereof.
"The sealing member may be in a form of an O-ring located along a periphery of the exposed end of the collecting plate.
"The insulation member may include a penetration hole through which the collecting plate passes. The sealing member may surround the periphery of the penetration hole.
"The sealing member may be continuously formed along the periphery of the penetration hole.
"The insulation member may include a sealing groove at a region corresponding to the sealing member, the sealing groove accommodating the sealing member.
"The sealing member may be adhered to the insulation member by an adhesion member and presses the cap plate and the terminal plate.
"The sealing member may include at least one selected from the group of foamed sponge, ethylene propylene diene rubber, acrylic rubber, silicone rubber, an elastomer, a thermoplastic elastomer, a thermoplastic urethane, a rubber-like material, and a polymer plastic.
"The sealing member may protrude relative to the insulation member in a state prior to the cap plate and terminal plate being coupled to each other, and may be compressively transformed in a state that the cap plate and the terminal plate are coupled thereto.
"The sealing member may be on a surface on which the insulation member makes contact with the cap plate. The insulation member further includes a ventilation groove on the surface.
"One end of the ventilation groove may be positioned within the periphery of the sealing member. Another end of the ventilation groove may extend to the exterior of the periphery of the sealing member.
"The other end of the ventilation groove may extend to an exterior edge of the insulation member.
"The sealing member may be a foamed sponge."
