Art [1] The present invention relates to a battery cell including a shield assembly for preventing short-circuit due to the needle-shaped conductor. BACKGROUND [2] Many studies on the development of technology and the demand of energy secondary batteries as and rapidly increases as the demand increases, the secondary battery (or "cells") that can meet the various requirements accordingly have been made to the mobile device . [3] The battery cell according to the shape of the battery case, the electrode assembly is a cylindrical battery and a prismatic battery that is embedded in a metallic can of cylindrical shape or square shape, the electrode assembly is an aluminum laminate sheet pouch case pouch-shaped battery that is embedded in the type of It is classified. [4] Also, the battery cells of jelly of a structure wound in the electrode assembly consisting of a positive electrode, a negative electrode and a separator interposed bar, typically a membrane of the long sheet-like positive and negative electrodes to be classified according to whether made of any structural state -roll (winding type) through the electrode assembly, a predetermined size of a plurality of positive and negative electrodes of a stacked sequentially stacked in a state of interposing the separator (multi-layer), an electrode assembly, a separator of the positive electrode and the negative electrode of a predetermined unit of a cut in a unit of after placement of the bi-cell (bicell) the unit cell laminate in a state or a pull cell (full cell) on the separating film, a stack of the winding structure / folding type electrode assembly, or a bi-cell (bicell) or a pull cell (full cell ) it may include the structure of the electrode assembly, such as a stack in a state of interposing the separator. [5] In recent years, as well as it lowers the ease of the manufacturing process, and manufacturing cost, in response to various types of devices, there are receiving attention battery cell including an electrode assembly that includes a structural applicability of the high pull cell or bi-cell. [6] On the other hand, the electrode assembly is as if to be pierced with a sharp needle-shaped conductor having electrical conductivity, such as a nail, the positive electrode and the negative electrode electrically connected to one another by a needle-like conductive current is caused to flow to the low-resistance acicular conductor. At this time, the generated deformation of the through-electrode, and a high heat resistance is generated by the current to be energized, the contact resistance between the positive electrode active material and negative electrode active material portion. And if the temperature due to heat of the electrode assembly to rise above the threshold value, the oxide structure of the cathode active material is collapsed, and to generate a thermal runaway which can act as a major source of ignition or explosion of the electrode assembly and the battery cell. [7] In addition, when in contact with the opposite pole of the electrode active material or collectors are mutually facing bent by the needle-shaped conductor has to further speed up the bars, a thermal runaway phenomenon described above, which is highly exothermic than the resistance heat generation, this problem is a large number of It may result in more serious in the electrode assembly including a bi-cell, and it includes electrodes. [8] Therefore, it is possible to prevent the short circuit, fire, explosion, etc. and more high situation there is a need for a battery cell structure to improve safety. Detailed Description of the Invention SUMMARY [9] An object of the present invention is to solve the technical problem, which has been requested from the problems, and of the prior art. [10] More specifically, it is an object of the present invention is to provide a battery cell including a shield assembly which can ensure the stability of the needle-shaped conductor. Problem solving means [11] The battery cell according to the first aspect of the present invention to achieve this object, [12] A battery cell including an electrode assembly, electrolyte, and the cell case, [13] At least the outer side of the one surface of both surfaces of the electrode assembly in the stacking direction of the electrode assembly has a shield (insulator assembly) of electrical insulation is added; [14] When the needle-shaped conductor to pass through the insulator assembly, as the needle end of the needle-shaped conductor portion of the insulator assembly dropped to be introduced through the electrode assembly with a needle-shaped conductor, and feed-through plane of the electrode assembly by the missing portion of the insulator assembly It characterized in that the contour is determined. [15] This When more specifically described, when the needle-shaped conductor through the battery cell in accordance with the present invention, there is a needle-shaped conductor, instead, missing the insulator assembly portion is configured to determine the through-type electrode assembly, in the needle-shaped conductor through hole the possibility of contact with the electrode of the electrode assembly inside can be remarkably reduced. [16] Therefore, in the present invention, and a plan view of the missing shield assembly portion is configured so that the vertical cross-sectional width greater than the widest portion in the needle-shaped conductor, This allows the loosening of the insulator assembly parts a through having a more planar compared to the vertical cross sectional area of ​​the needle-shaped conductor It is capable of forming a sphere. [17] Needle-shaped conductor is defined in the present invention can be understood with sharp and long form of the absence of nails, screws, bolts or the like. [18] Thus, the following description assumes as a nail is a sharp edge as an example of the needle-shaped conductor, and the specific detailed structure and the operation structure of the insulator assembly. [19] In one specific example, the shield assembly consisting of a structure with more than one insulator are laminated; [20] The shield assembly consists of a structure in which two or more stacked single insulator or insulator; [21] The insulator may be a structure that comprises a plurality of missing pattern, it is formed on the insulating body and the insulating body. [22] The insulating body has an insulating excellent polyimide, silicone, Teflon, aramid fiber (Aramid fiber), glass fibers from the group consisting of (Glass fiber), UHMWPE fiber (Ultra-highmolecular-weight polyethylene fiber) and a PBO fiber (Polybenzoxazole fiber) one member selected may be equal to or greater than. [23] More than one insulator in said insulator assembly are, can be a missing part pattern is formed in each of the insulator are laminated in a form that does not overlap each other. [24] This laminated structure is so lacking part pattern onto the plane can be arranged relatively tight, it is possible to minimize the dead zone is formed on the through-the needle-shaped conductor. [25] In contrast, in the case of a single insulator, it is advantageous in terms of the thickness and the volume of the bar, the battery cell having a relatively thin thickness. [26] In some cases, there may be at least one side of the outer surface of the insulator, the insulating coating such as a fluorine, enamel, silicone is applied. [27] When the present invention to the needle-like conductive pattern, through the loosening, and by a needle-like end portion of the needle-shaped conductor that is introduced into the shield assembly, the missing pattern is able to penetrate the electrode assembly with a needle-shaped conductor in a state of being dropped from the insulating body. [28] This pattern is missing, [29] Missing portions so as to have a tensile strength that is not damaged during penetration of the electrode assembly is made of a metal, high-strength plastic or ceramic; And [30] In the adjacent region and the center of the missing portion, needle-like, which is perforated in two-dimensional size of 50% to 80% compared to a flat portion missing conductor leading part; [31] And including; [32] If needle-shaped conductor leading part is fixed to the needle end of the needle-shaped conductor, missing portion along the needle-shaped conductor in the insulating body from the missing state proceeds to the axial direction and can pass through the electrode assembly. [33] Thus, when the inevitable penetration of needle-shaped conductor, a non-conductive needle-like, while the addition of missing fixed to the needle-shaped conductor through the electrode assembly, there is a phenomenon in which needle-shaped conductor is in direct contact with the electrodes can be suppressed. [34] In one specific example, the missing to determine a feed-through plane shape and area formed in the additional electrode assembly, it has a total plan area of missing pattern 7 mm 2 to 200 mm 2 may be, specifically, 20 mm 2 to 95 mm 2 can be. [35] The flat is not common in the industry, with screws, to be set in consideration of the size of the bolt or the like, the diameter of the typical needle-shaped conductors about 1 mm to 10 mm of the bar, that missing portion is formed having a greater planar than those of the vertical cross-sectional area per since the through-plane sphere diameter larger than the diameter of the needle-shaped conductor, is remarkably low possibility to be a needle-shaped conductor through hole in contact with the electrodes in the. [36] Thus, in order to pass through the missing portion, and the electrode assembly have a strength enough not to be broken in the through-process, and the tensile strength of the missing be 1 Kg / cm to about 10 Kg / cm in the invention for this purpose. [37] In the present invention, the high strength plastic is polyamide, polyacetyl, polycarbonate, polyester resin, polyphenylene oxide, a polyolefin, a polyimide, a silicone, Teflon, aramid fiber (Aramid fiber), glass fibers (Glass fiber), UHMWPE It may be formed of one selected from a fiber (Ultra-highmolecular-weight polyethylene fiber) and a PBO fiber (Polybenzoxazole fiber). [38] In some cases, the dielectric body also may be made to the high-strength plastic. [39] The metal may be an aluminum, copper, SUS, dura titanium, palladium, platinum, one species, or two or more alloys selected from the group consisting of nickel and molybdenum, but is not limited to these. [40] In some cases, there may be a surface of the metal-organic insulating coating, an inorganic insulating coating or anodized (anodizing) is processed. [41] In one specific example, the needle-shaped conductor guide portion can have, which may be drawn along the needle end of the needle-shaped conductor, the insulating film is added to the addition. [42] This insulating film is stretched while in the form that wraps by the frictional force, needle-shaped conductor and the missing portion, it is possible to prevent the needle-shaped conductor and the electrodes are in direct contact. [43] The thickness of the insulating film may be at least 15 microns or more may be made to the thickness, particularly, of 20 microns thickness. This is to be taking into account the elongation of the insulation film, when the thickness of the insulating film is less than 15 microns, which is not the bar can not be expected for the stretching degree of wrap portions missing the conductive needle, preferably. [44] The insulating layer may be an SRS (Safety-Reinforcing Separators) membrane of organic / inorganic composite porous. [45] The SRS is a separator, even if due to the heat resistance of the inorganic particles does not occur in the high-temperature heat-shrinkable bar, the through-electrode assembly by a needle-shaped conductor, it is possible to maintain the elongation of the insulation film. [46] The SRS may be a membrane component an active layer comprising inorganic particles and a binder polymer on a polyolefin-based separator substrate coated structure. [47] This, SRS separation membrane may have a uniform pore structure formed by the empty space (interstitial volume) between the active ingredients of the inorganic particles with a pore structure comprising a membrane substrate itself, the pores of the external force applied to the electrode assembly as well as to significantly reduce the impact, smooth movement of lithium ions is made through the pores, since a large amount of electrolyte can be filled in to indicate the high impregnation rate, an attempt can be made with the improved performance of the battery. [48] The separator substrate and the active layer may be a rigidly coupled physically polyolefin-based separator substrate surface pores and the active layer are mutually entangled separator substrate and the active layer and in the form (anchoring) with the, at this time, the separator substrate and the active layer is the physical consider the pore structure present on the bonding force with the separation membrane to 9: 1 to 1: 9 can have a thickness ratio of, specifically, 5: can have a thickness ratio of 5. [49] SRS in the membrane, one active component formed on the pore part of the surface and / or polyolefin-based separator substrate in the substrate is inorganic particles that are commonly used in the art. [50] The inorganic particles allows for the formation of empty spaces between the inorganic particles are gyeomhage serves a kind of spacers (spacer) that can maintain the role and physical forms to form the micropores. Further, the inorganic particles generally will have a formed organic / inorganic composite porous film have excellent heat resistance since it has the characteristic that does not change the physical properties even if the high-temperature more than 200 ° C. [51] The inorganic particles, just electrochemically stable is not particularly limited. That is, as long as the inorganic particles that can be used in the present invention, the operating voltage range of the battery is applied (e. G., Li / Li + reference to 0 ~ 5V) oxide and / or a reduction reaction does not occur in not particularly limited. In particular, in the case of using the inorganic particles in the ion conductivity, it is possible to improve performance, increase the ion conductivity in the electrochemical device, it is preferred that a high ionic conductivity as possible. Further, when the inorganic particles have a high density, as well as a difficulty in dispersion during coating, because another problem of the increase in weight in the manufacture batteries, it is preferred that the smallest possible density. In the case where the high dielectric constant inorganic material, it is possible to contribute to the electrolyte liquid electrolyte salt, such as increased dissociation of lithium salts to increase the ionic conductivity of the electrolyte. [52] Because of the aforementioned reasons, the inorganic particles (a) may be at least one member selected from the group consisting of inorganic particles with inorganic particles, and (b) lithium ion conductivity having piezoelectricity (piezoelectricity). [53] The piezoelectricity (piezoelectricity) inorganic particles and pressure in the non-conductive, or by the internal structure change when a certain pressure is applied as meaning a material with physical properties of electricity is passing through, as well as the dielectric constant exhibit 100 or more high-k characteristics constant pressure applying to one side of the electric charge is generated when the tension or compression of the amount, the other side is a substance having the function of a potential difference occurs between both sides, each being charged negatively. [54] When using the inorganic particles having the same characteristics as the porous active ingredient, in this case that the internal short circuit between electrodes caused by an impact due to the inorganic particles coated on the membrane an anode and a cathode, such as a needle-shaped conductor is not in direct contact with in addition, an attempt can be made to be due to the piezoelectricity of the inorganic particles occurs within a potential difference between the particles and this electron transfer between the electrodes, i.e. by the yirueojim flow of minute electric current, reducing the voltage of the gentle cell and improve safety resulting. [55] Examples of the inorganic particles having the piezoelectricity is BaTiO 3 , Pb (Zr, Ti) O 3 (PZT), Pb 1 - xLa x Zr 1-y Ti y O 3 (PLZT), PB (Mg 3 Nb 2/3 ) O 3 -PbTiO 3 (PMN-PT) and hafnia (HfO 2 but be at least one selected from) the group consisting of, but is not limited to such. [56] Inorganic particles having the lithium ion conductivity is, but containing a lithium element as referring the inorganic particles having the ability to move the lithium ions nor not store lithium, inorganic particles having lithium ion conductivity are present in the internal particle structure it is possible to transfer and move lithium ions due to the type of defect (defect), and improves lithium ion conductivity within the cell, thereby it is possible to improve the battery performance. [57] Examples of the inorganic particles having the lithium ion conductivity include lithium phosphate (Li 3 PO 4 ), lithium titanium phosphate (Li x Ti y (PO 4 ) 3 , 0
