Samsung SDI : Patent Application Titled "Rechargeable Battery" Published Online

03/26/2015 | 03:24pm US/Eastern

By a News Reporter-Staff News Editor at Politics & Government Week -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventor HAN, Min-Yeol (Yongin-si, KR), filed on April 7, 2014, was made available online on March 19, 2015.

The assignee for this patent application is Samsung Sdi Co., Ltd.

Reporters obtained the following quote from the background information supplied by the inventors: "Embodiments relate to a rechargeable battery

"A rechargeable battery is a battery that can be repeatedly charged and discharged, unlike a primary battery. A low-capacity rechargeable battery may be used for small portable electronic devices such as a mobile phone, a notebook computer, and a camcorder. A large-capacity rechargeable battery may be used as a power supply for driving a motor such as for a hybrid car.

"The above information disclosed in this Background section is only for enhancement of understanding of the background of the described technology and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "Embodiments are directed to a rechargeable battery.

"The embodiments may be realized by providing a rechargeable battery including an electrode assembly including a separator, and a negative electrode and a positive electrode provided on opposite surfaces of the separator; a case accommodating the electrode assembly therein; a cap plate coupled to the case; a negative electrode terminal and a positive electrode terminal respectively connected to the negative electrode and the positive electrode, the negative electrode terminal and positive electrode terminal extending through a terminal hole of the cap plate; a safety member between the electrode assembly and the case; and a first resistance member connecting the safety member with the negative electrode.

"The rechargeable battery may further include an insulation member, wherein the safety member includes a plate portion on a flat side surface of the electrode assembly, the insulation member being on the plate portion, and a protrusion that protrudes from the plate portion and is connected to the first resistance member.

"The protrusion may protrude from the plate portion at a region that is closer to the positive electrode terminal than the negative electrode terminal.

"The first resistance member may have a band shape and is spaced apart from the plate portion, a first end of the first resistance member being connected to the protrusion and a second end of the first resistance member being connected to a negative electrode lead tab that is connected to the negative electrode.

"The first resistance member may be vertically between the electrode assembly and the cap plate.

"The first resistance member may include a pair of first sub-resistance members, one of the first sub-resistance members being vertically between the electrode assembly and the cap plate, and the other of the first sub-resistance members being vertically between the electrode assembly and a bottom of the case.

"The safety member may include a pair of the protrusions, one of the protrusions protruding upwardly from the plate portion and being connected to the one of the pair of first sub-resistance members, and the other of the protrusions protruding downwardly from the plate portion and being connected to the other of the pair of first sub-resistance members.

"The first resistance member may have a bent shape, may be separate from the plate portion, and may have a first end connected to the protrusion and a second end connected to a negative electrode lead tab, the negative electrode lead tab being connected to the negative electrode.

"The rechargeable battery may further include a second resistance member connecting the positive electrode terminal with the cap plate.

"The positive electrode terminal may include a rivet terminal in the terminal hole of the cap plate; a widely-formed flange inside the cap plate and integrated with the rivet terminal; and a plate terminal outside of and insulated from the cap plate, the plate terminal being electrically connected to the rivet terminal.

"The plate terminal may include a through hole into which the rivet terminal is inserted, and a connection portion protruding from a side thereof, the connection portion being connected to the second resistance member.

"The second resistance member may have a plate shape and includes a pair of through holes at opposite sides thereof, a first one of the through holes may be on a first mounting member that protrudes from the connection portion, and a second one of the through holes may be on a second mounting member that protrudes from the cap plate.

"Each of the first mounting member and the second mounting member may have threads at an end portion thereof, the second resistance member being mounted on the first mounting member and the second mounting member and being fastened to the first mounting member and the second mounting member by a nut.

BRIEF DESCRIPTION OF THE DRAWINGS

"Features will be apparent to those of skill in the art by describing in detail exemplary embodiments with reference to the attached drawings in which:

"FIG. 1 illustrates a perspective view of a rechargeable battery in accordance with a first exemplary embodiment.

"FIG. 2 illustrates a cross-sectional view of the rechargeable battery taken along a line II-II of FIG. 1.

"FIG. 3 illustrates an exploded perspective view showing an electrode assembly, first and second insulation members, a safety member, and positive and negative electrode lead tabs.

"FIG. 4 illustrates a cross-sectional view of the rechargeable battery taken along a line IV-IV of FIG. 2.

"FIG. 5 illustrates an exploded perspective view showing a structure in which a cap plate and a positive electrode terminal are electrically connected to each other.

"FIG. 6 illustrates an exploded perspective view showing an electrode assembly, first and second insulation members, a safety member, and positive and negative electrode lead tabs in a rechargeable battery in accordance with a second exemplary embodiment.

"FIG. 7 illustrates an exploded perspective view showing an electrode assembly, first and second insulation members, a safety member, and positive and negative electrode lead tabs in a rechargeable battery in accordance with a third exemplary embodiment."
