This application claims the benefit of priority based on the date of July 6, 2017 Korea Patent Application No. 2017-0085693 years, and all information disclosed in the literature of the Korea patent application are included as part of the specification. [2] In the present invention has to be, more specifically, the notch, the size of depth to width of the electrode lead connected to the electrode tab varies about the pouch type secondary battery including an electrode lead is an asymmetric notch is formed is formed on the electrode in a desired condition made to facilitate the breaking of the lid is a secondary battery having a characteristic that the secondary battery can be disconnected. BACKGROUND [3] In general, the kind of the secondary batteries include nickel-cadmium batteries, nickel hydrogen batteries, lithium ion batteries and lithium ion polymer batteries. The secondary battery is large products high power is required, such as a digital camera, P-DVD, mobile phones, wearable device (Wearable Device), small products such as Portable Game Device, Power Tool and E-bike, as well as electric cars or hybrid cars and also it used for the power storage device and a backup power storage device that stores surplus generated power and renewable energy. [4] Such a secondary battery is, in the shaped surface of the battery is high, the demand for prismatic secondary batteries or pouch type secondary batteries with a thin thickness can be applied to products such as a mobile phone, the material surface in a high energy density, discharge voltage, output stability the high demand for lithium secondary batteries such as lithium ion batteries, lithium ion polymer batteries. [5] Further, the cylindrical battery cell, a prismatic battery cell, a pouch-shaped battery may be classified into a cell or the like, among them can be stacked in high integration, and ease of the pouch-shaped battery cell is low and deformation high energy density per weight, depending on its shape It has attracted a lot of attention. [6] On the other hand, generally cylindrical battery cell and a prismatic battery cell, using a phenomenon in which the battery cells swell during the pressure increase due to a malfunction to the overcharge of the battery mechanical current to block the series connection of cells is physically blocked device (CID, Current , the pouch-shaped battery cell while using the Interrupt Device) does not include such a member. [7] Thus, the pouch-shaped battery cell case by abnormal use of battery cells flowing overcurrent, failure to block it in advance, there is a problem that may occur explosion. [8] In addition, this to solve the problem but can be considered the addition of a separate device within the cell, since the problem, the capacity of the battery cell decreases, it does not meet the trend for the manufacture of a battery cell of the high-capacity high-efficiency. [9] In this regard, Korea Patent Laid-Open Publication No. 2016-0129763 discloses, as for a battery having a thermal expansion coefficient of the bimetal tab configured to one another in different metal, the bimetal tab is the upper portion of the bimetal tab at a high temperature under abnormal operating conditions of the cell and the lower the thermal expansion is so different discloses a technique of causing a short circuit from the electrode lead. [10] In Korea Patent Application No. 1,601,123 discloses a first-electrode lead connected to the electrode tab, and a secondary battery including a second electrode lead wherein the first electrode lead and detachably connected which extends exposed from the inside of the battery case to the outside for such, when the battery internal pressure rise due to abnormal conditions of the battery are detached from each other to the electrode lead discloses a technique in which the current is blocked. [11] Korea Patent Publication No. 1614434 discloses, whereby due to the occurrence of short-circuit when the over-current flowing through the secondary battery, connecting parts provided on the current path is quickly broken flowing through the secondary battery, so blocking the overcurrent to ensure usability of the safety secondary battery It can discloses a secondary battery. [12] Korea Patent Laid-Open Publication No. 2012-0139590 discloses, in the case where the temperature of the lead-free solder bridge includes the carpet separation unit an overcurrent flows through the electrode lead to rise to 150-300 degrees, carpet separate electrode lead is a fracture due to over-current parts of the heart of flow, it discloses a secondary battery that is the ratio regional block. [13] However, the ease of rupture in its own electrode lead connected to the electrode tab structure is formed, there is no recognition of the techniques that are fast, accurate current is interrupted in abnormal operating conditions of the battery cell. [14] Accordingly, in the case of the pouch-shaped battery cell, the situation is high, the need for a separate technology to block the current in an abnormal state such as the volume expansion of the battery cell without having an additional device. Detailed Description of the Invention SUMMARY [15] The present invention for solving the problems of the prior art, to form an asymmetrical notch for inducing breakage of the electrode lead on one side of the electrode lead electrically connected to the electrode taps of the electrode assembly, the abnormal use of the secondary battery, such as the swelling occurs due to, and in the notch portion of the object of the present invention to provide a technology that enables the electrode lead can be quickly broken. [16] Further, by forming not a constant depth to the width of the notch, fast even relatively If the deep width of the bar to more quickly lead to breakage of the electrode lead from the wide portion, the cell pressure in the cell depth of the notch weak it is possible to cut off the current. [17] Accordingly, in the case of the abnormal use of the secondary battery, it is possible to prevent an explosion of the hot ignition phenomena, safety can be provided an improved secondary battery. Problem solving means [18] The pouch type secondary battery of the present invention to achieve this object, in the pouch-shaped secondary battery with a separator having a through state including an electrode assembly of the stacked positive electrode and the negative electrode, [19] One surface of the electrode lead electrically connected to the electrode taps of the electrode assembly are formed in the asymmetrical shape notched to induce breakage of the electrode lead, and [20] The other surface side of the electrode lead, and has a lid film for improving the adhesion of the electrode leads and the battery case is attached, [21] The lead films, the films may be of a second lead which is located on the electrode lead protruding direction in a first film and a lead battery case which is located outside the housing the electrode assembly direction around the notch. [22] In this way, and are there formed with a notch one face of the electrode lead that is connected to the electrode taps, in the electrode lead on both sides, since the lead film to improve the adhesion to the battery case is mounted, the battery cell internal pressure is increased battery case is when the expansion there is a breakage of the electrode leads can be derived. [23] Accordingly, in the case of the pouch type secondary battery in the prior art, there is no device, such as a CID element that blocks the connection of the battery physically with the inflation pressure of the battery case of the malfunction of the battery, unlike the secondary battery, the metal can type, heat generation of the cell to when the expansion can solve the difficult problem to block the fast current to the initial state. [24] Further, since a separate additional member for rapid current blocking it does not contain therein the battery cell, to avoid the problem that the capacity of the battery decreases, and there is an advantage that can be used as it is a conventional battery cell manufacture. [25] One In a specific example, the first lead film is moving the electrode lead fracture due to the bar, wherein the one lead film attached battery case direction to position only the other surface of the electrode lead the reverse side of the surface with a notch formed in the electrode lead can. [26] The second lead film has at least a portion may be located so as to overlap each other, bars, that is, the second lead film in the surface of the electrode leads and the other surface to the center of the electrode lead is the sealing of the battery case at the attachment to the electrode lead status When made to the heat-sealed, can be attached so as to surround both side surfaces of the electrode leads from the electrode lead. [27] The second lead film, the plane size of the lower lid film which is located on the lower face of the upper lid film and the electrode lead which is located on the upper surface of the electrode lead may be different from each other, for example, the second lead film, relative to the electrode lead may be less than the size of the lead film which is located in the direction in which the size of the lead film attached to the direction in which the first lead opposite to the film position. [28] Thus, if in the cut of the lead film of a fracture, in the the second lead film fixed to the sealing portion of the electrode leads attached to the battery case condition, it is attached to the orientation notch is formed in the electrode leads and the relatively large go to great claim 2 lead film is adhered battery case direction, and is attached to the orientation notch is not formed in the electrode leads the first lead film is attached in the electrode lead is moved to the cell case the direction of the first lead film is adhered do. [29] That is, the first case where the lead film is attached only to the other side not provided with the notch of the electrode lead, the second lead film is not attached to a different sizes with each other at both sides of the electrode lead, the electrode lead is broken electrode to one side of the lid unit move to the upper case direction, and the other side of the electrode lead is moved to the lower case direction one end portion of the movement to the lower case direction, or the electrode leads are guided to move into the upper case the direction of the electrode lead the other side is It is intended. [30] In one specific example, the electrode lead is connected to the electrode tab is desired bar, said notch being formed so as to rupture in a direction perpendicular to the longitudinal direction of the electrode lead protrudes outside the battery case is, in the longitudinal direction of the electrode lead at one end of the electrode lead in a direction perpendicular to the other end it may be formed in a continuous shape. [31] Further, the notch is to be rapidly and accurately formed in the electrode lead is broken portion, the notch can be more preferably made as compared to that made of a certain size and shape, asymmetrical shape. [32] Specifically, a concave central depth of the notch when the length of the first direction is the electrode lead bar, which can be formed so as to increase in a first direction parallel to the direction perpendicular to the longitudinal direction of the electrode lead to the longitudinal axis, whereby as a horizontal axis perpendicular to the direction, it may be a direction toward the left side from the right side, or may be a direction from the left to right. [33] That is, the concave depth of the center of the notch can be increased to the right in a row in a direction toward, or discontinuously in a direction toward the left side from the right side of the electrode lead, or to the left, it is preferable to be increased continuously. [34] Further, the width of the notch may be started a concave central depth is increased fracture from the center of the largest depth and the width portion of the bar, a notch can be increased in the first direction to the notch. [35] In one specific example, the thickness of the electrode lead part of the said notch is formed may be may be a 10% to 90%, based on the thickness of the electrode leads are notch is not formed, specifically 30% to 80%. When the electrode lead thickness of the portion where the notch is formed when, based on the thickness of the electrode lead not provided with the notch is less than 10%, and in normal operation of the battery cell and the electrode leads it can be broken, greater than 90%, the desired Since it is difficult to achieve the object, for deriving the breakage of the electrode lead from the environment it is not desirable for. [36] On the other hand, a concave central depth of the notch is the ratio of the minimum value to the maximum value of the bar, a notch depth that increases continuously or discontinuously can be from 0.1 to 0.9 may be, in particular from 0.3 to 0.7. [37] In one specific example, the electrode lead may be of a notch in the center a first lead film is attached to the inner electrode lead, and the second lead outside electrode lead of the film is attached, the inner electrode lead and the outer electrode lead is located in said notch in the breaking state can each be attached respectively to any one of the upper case or the lower case.
