By a News Reporter-Staff News Editor at Journal of Engineering -- A patent by the inventor Kim, Dukjung (Yongin-si, KR), filed on February 24, 2012, was published online on July 21, 2015, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.
Patent number 9088024 is assigned to SAMSUNG SDI CO., LTD. (Suwon-si, Gyeonggi-do, KR).
The following quote was obtained by the news editors from the background information supplied by the inventors: "Embodiments relate to a secondary battery.
"Secondary batteries are rechargeable, unlike primary batteries. Secondary batteries may include a low capacity battery including a battery cell in the form of a pack may be used for small portable electronic devices, e.g., cellular phones and camcorders. A high capacity battery including dozens of battery cells connected to one another may be used as a motor-driving power source for electric scooters, hybrid vehicles, or electric vehicles.
"Secondary batteries may be manufactured in various shapes, e.g., a cylindrical shape and a prismatic shape. A secondary battery may be manufactured as follows: an electrode assembly formed by disposing an insulating separator between a positive electrode plate and a negative electrode plate is placed in a case together with electrolyte, and a cap plate is disposed on the case. The electrode assembly may be connected to positive and negative terminals which protrude from the cap plate and are exposed to the exterior of the electrode assembly."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "Embodiments are directed to a secondary battery.
"The embodiments may be realized by providing a secondary battery including an electrode assembly; a collecting plate electrically connected to the electrode assembly; a case accommodating the electrode assembly and the collecting plate; a cap plate coupled with the case; an electrode terminal electrically connected to the collecting plate, the electrode terminal extending through the cap plate; and an insulation cover member covering regions of the electrode terminal and the collecting plate, the regions of the electrode terminal and the collecting plate being between the cap plate and the electrode assembly.
"The collecting plate may include a head part connected to the electrode terminal; and a support part, the support part being bent from the head part, extending in a first direction, and being electrically connected to the electrode assembly.
"The insulation cover member may include a fixing part fitted around the support part of the collecting plate; and an accommodation part extending from the fixing part and accommodating the electrode terminal and the head part of the collecting plate.
"The fixing part may include an outer wall part, and first and second sidewall parts, sides of the first and second sidewall parts being connected to ends of the outer wall part, and other sides of the first and second sidewall parts being connected to the accommodation part, and the support part of the collecting plate may be in a space surrounded by the outer wall part and the first and second sidewall parts.
"The accommodation part may include an accommodation recess, the electrode terminal and the head part of the collecting plate being coupled with the accommodation recess.
"The accommodation recess may include at least one stepped part.
"The accommodation part may include a guide recess connected to the accommodation recess, and a side of the head part of the collecting plate may be fixed to the guide recess.
"A first surface of the accommodation part may include at least one protrusion thereon.
"The cap plate may include at least one coupling recess therein, the coupling recess being coupled with the at least one protrusion, and a number and shape of the at least one coupling recess may correspond to a number and shape of the at least one protrusion.
"A second surface of the accommodation part may include at least one fixing surface thereon, the at least one fixing surface corresponding to an outer surface of the electrode assembly.
"The second surface of the accommodation part may include a positioning protrusion thereon, the positioning protrusion being between neighboring fixing surfaces.
"The secondary battery may further include a sealing member between the electrode terminal and the cap plate.
"The sealing member may include a body part having a planar plate shape, the body part including a penetration hole through which the electrode terminal extends; and a protrusion extending from the penetration hole in a second direction opposite to the first direction, the protrusion surrounding the electrode terminal.
"The body part may further include at least one sub body part extending outwardly from the body part.
"The sealing member may include at least one ridge and at least one furrow arranged around the penetration hole.
"The electrode terminal may include a plate-shaped connection part contacting the head part of the collecting plate; and a column part protruding from the connecting part and extending through the cap plate, and the body part of the sealing member may have a shape corresponding to a shape of the connection part.
"The sealing member may be formed of rubber."
