Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The above objects, features and advantages of the present invention can be more readily understood by referring to the accompanying drawings and the following detailed description. In the description of the present invention, when it is determined that specific descriptions about related known structures or functions may make the gist of the present invention unclear, detailed descriptions thereof will be omitted.
In describing the components of the present invention, terms such as first, second, A, B, (a), (b), and the like may be used. Such terms are only used to distinguish one structural element from another structural element, and the nature or order or sequence of the respective structural elements is not limited to the terms. It is to be understood that, for example, when an element is referred to as being "connected," "coupled" or "coupled" to another element, it can be directly connected or coupled to the other element or be "connected," "coupled" or "coupled" to another element.
Referring to the drawings, the present invention provides a battery plate fixing structure, including: a battery 10 having a separator 16 interposed between a plurality of anode plates 12 and cathode plates 14; and a fixing support 30 provided at a peripheral portion of the battery 10. The battery pole plate fixing structure can be called as a battery internal pole plate anti-shaking structure.
In one embodiment of the present invention, the battery 10 is prepared in a roll form by winding. The battery 10 has a structure in which a separator 16 is interposed between a plurality of anode plates 12 and a plurality of cathode plates 14. Hereinafter, the anode plate 12 and the cathode plate 14 are referred to as plates for convenience.
In the present invention, a laminated battery in a form in which a jelly roll wound in a roll form and a plurality of anode plates and cathode plates are laminated with separators interposed therebetween may be inserted into a bag or a can and fixed. That is, it should be understood that the battery 10 described in the present invention is a concept including a battery roll and a laminated battery in a wound form.
Since the electrode plates stacked in the zigzag form of the battery 10 are in a floating state (floating state) by the active material, positional variation of the electrode plates is easily caused by external physical force, self-vibration, or the like. This causes problems such as reduction in the capacity of the battery and short-circuiting, and thus causes problems of defects and safety. Therefore, in the present invention, after stacking the cells 10 (gel rollers), the lower end portion is coated with an ultraviolet curing coating agent and irradiated with a curing lamp for a predetermined time, thereby maintaining the positions of the electrode plates within the cells 10 in the initial form.
When the battery 10 is terminated with the separator 16 and fixed to the outside with a Tape (Tape) or an adhesive (bond), the electrode plates may fall in the grid (grid) direction or the opposite direction, and the electrode plates inside the battery 10 cannot be fixed and may be positionally changed although they are surrounded with the Tape or the like at present.
Therefore, in the present invention, in the process of laminating the electrode plate and the separator 16 to form the battery 10, the ultraviolet curing coating agent is applied to the peripheral portion of the electrode plate exposed to the outside and cured. The ultraviolet curing coating agent is applied as a fixing support 30 to the periphery of the battery 10 and cured by a curing means such as a lamp. However, the ultraviolet curable coating agent functions as a support for holding the electrode plate and the separator 16, thereby preventing the electrode plate inside the battery 10 from flowing or deforming. It should be understood that the fixing support 30 may be any means that can fix the electrode plate and the separator 16, other than the uv curable coating agent.
In another aspect, the present invention provides a battery plate fixing method, including: a step of preparing the battery 10 with the separator 16 interposed between the plurality of anode plates 12 and cathode plates 14; and a step of fixing a plurality of electrode plates (the anode plate 12 and the cathode plate 14) of the battery 10 by forming a fixing support 30 at the peripheral portion of the battery 10. At this time, the plurality of electrode plates and the plurality of separators 16 may be fixed by the fixing supports 30. As described above, the operation can be performed in connection with the manufacturing process by applying the curing coating agent in a predetermined form to the lower end portion of the battery 10 (gel roll), applying the curing coating agent, and then rapidly curing the coating agent to form the fixing support portion 30. The curing coating agent forming the fixing support portion 30 may be formed by applying and curing an ultraviolet curing coating agent, or may be applied to the battery 10 (gel roll) by using a substance having a similar function in a liquid or liquid phase form. It can also be applied in the form of a Gel (Gel) or Spray (Spray). The applied curing coating agent may be cured by irradiating a curing lamp. The fixed support 30 is formed in a state where the curing coating agent is cured by a curing lamp. The coating form of the above-mentioned curable coating agent may be various forms such as "S" form, dot form, spray form, and the like.
Therefore, according to the present invention, since the plurality of electrode plates in the battery 10 are not displaced, the battery can be stably output, and the falling-off of the active material due to the fluctuation of the electrode plates can be prevented, thereby eliminating the problem. In the case of a large-capacity battery, deformation of the electrode plate due to vibration becomes a problem, but in the present invention, the problem of battery failure can be solved without movement of the electrode plate.
In the present invention, in the use of a secondary battery having a battery, the active material applied to the anode plate 12 and the cathode plate 14 is inclined to one side of the battery by a phenomenon that the secondary battery is inclined to one side or the like, or, even if the separator 16 is to be reduced, the above-described fixing support portion 30 holds and supports the separator 16, so that the end portions of the anode plate 12 and the cathode plate 14 are exposed to the outside more than the separator 16, thereby blocking the possibility of the anode plate 12 and the cathode plate 14 being short-circuited with each other, as described above, the serious consequence of the battery such as the secondary battery being not used for a long time is prevented in advance by blocking the possibility of the anode plate 12 and the cathode plate 14 being.
On the other hand, in another embodiment of the present invention, a laminated battery in which a separator is interposed between a plurality of rectangular plate-shaped electrode plates is inserted into a bag or a can and fixed. For convenience, the above-described laminated battery is also referred to as a battery 10. In another embodiment of the present invention, the structure and method of fixing the battery 10 by inserting it into the pouch or can are the same as those of the above-described embodiment of the present invention, and the effects thereof are also the same, so that the repeated explanation thereof will be omitted.
In this case, as shown in fig. 4, the fixing and supporting part 30 may be provided not only at the upper end of the battery 10 but also at the lower end of the battery 10. A fixing support 30 may be provided at the lower end of the battery 10 from which the cap protrudes.
On the other hand, in the case of the laminated battery formed by laminating the separators 16 between the plurality of anode plates 12 and cathode plates 14, the fixing support 30 is formed at all the peripheral portions of the battery. The fixing support portions 30 are formed not only at the upper and lower end portions of the battery, but also at both side end portions of the battery. Please refer to fig. 5.
Then, the fixing and supporting part 30 grasps the side end parts of the plurality of separators 16, thereby preventing a phenomenon in which the anode plate 12 and the cathode plate 14 are exposed to the outside of the separators 16 even when the separators 16 of the battery are shrunk or the active materials applied to the anode plate 12 and the cathode plate 14 are inclined to one side of the battery during the use of the secondary battery, thereby preventing the anode plate 12 and the cathode plate 14 from being short-circuited.
On the other hand, in the case of the laminate type battery, the area of the separator 16 is made larger than the areas of the anode plate 12 and the cathode plate 14 so that the end of the separator 16 protrudes more than the ends of the anode plate 12 and the cathode plate 14, and penetrates the plurality of separators 16 to be combined with the fixing member 40, the fixing member 40 and the separator 16 are fixed by the curing agent to support the ends of the anode plate 12 and the cathode plate 14 by the fixing member 40. The fixing member 40 has a pin shape, a hole is formed in each of the diaphragms 16, and the fixing member 40 and the diaphragms 16 are fixed by a curing agent after the fixing member 40 is inserted into the hole of each of the diaphragms 16. This configuration may be referred to as a stitch-fastening of the fastening member. Please refer to fig. 6.
As described above, when the fixing member 40 is coupled so as to penetrate through each of the separators 16, the fixing member 40 is configured to hold and support the plurality of separators 16, and thus, during use of the secondary battery, it is possible to prevent the plurality of separators 16 from being reduced and entering more inward than the peripheral portions of the anode plate 12 and the cathode plate 14, in other words, it is possible to prevent the peripheral portions of the anode plate 12 and the cathode plate 14 from being exposed more than the peripheral portions of the plurality of separators 16 due to the reduction in size of the plurality of separators 16 during use of the secondary battery, and thus it is possible to prevent a short circuit phenomenon in advance due to contact between the anode plate 12 and the cathode plate 14 and more reliably prevent the battery of the secondary battery from being damaged due to a short circuit between the anode plate 12 and the cathode plate 14.
Specific embodiments of the present invention have been described in detail above. However, it is to be understood that the spirit and scope of the present invention is not limited to the specific embodiments, and those skilled in the art to which the present invention pertains may be variously modified and changed within a range not changing the gist of the present invention.
Therefore, the above-described embodiments are provided to enable those skilled in the art to more fully understand the present invention, and are intended to be illustrative in all respects, rather than restrictive, of the present invention, and the present invention is defined by the scope of the claims.
