Definitions
- the present invention relates to an electrochemical device utilizing an electrochemical reaction such as an organic electrolyte battery used for a main power supply of an electronic device or a power supply for a memory pack, or an electric double layer capacitor or an aluminum electrolytic capacitor. More specifically, the present invention relates to an electrochemical device having a configuration capable of confirming a state of application of a sealant disposed in a sealing portion of a container. Background technology ''
- electrochemical elements are composed of an element unit in which a pair of electrodes are opposed to each other via a separator, an electrolytic solution, and a container for accommodating them.
- This container is generally composed of a metal case having an opening and a sealing body for closing the opening.
- a gasket may be interposed between the metal case and the sealing body in order to secure electrical insulation between them.
- a sealant is provided between the metal case and the sealing body or between the gasket and the metal case or the sealing body.
- the shape of the metal case includes a bottomed cylindrical shape, a square shape, and a button shape. The sealant is required to have a function of preventing leakage and evaporation of the electrolyte to the outside, and a function of preventing moisture from entering from the outside.
- the sealing agent is mainly used to prevent the intrusion of water into the device, since water has a bad effect on the non-aqueous electrolyte and the electrodes. Is used.
- the present inventors have conducted detailed studies on the cause of liquid leakage, and found that variations in the position of application of the sealant and the uniformity of the film made of the sealant may cause liquid leakage. . Furthermore, since the sealant previously proposed by the inventors is colorless and transparent, the application position and the uniformity of the film in a state where the sealant is applied to the gasket are confirmed by visual observation or image recognition. It is very difficult. For this reason, evaluation of coating position and uniformity of coating film It is probable that the device whose value deviated from the specified value could not be excluded as a defective product in the manufacturing process, leading to the occurrence of liquid leakage. A prior example in which the application state of the sealant is determined based on image data in order to prevent such problems from occurring.
- Japanese Patent Application Laid-Open No. 3-37955 discloses a configuration in which a white powder or a luminescent agent is added to a sealing agent to distinguish it from the background as an auxiliary means for performing image recognition. I have. However, since these powders and the luminescent agent have almost no function as a sealing agent, the sealing performance may be deteriorated in some cases. In view of the above problems, the present invention does not adversely affect the properties of the sealant, and at the same time, positions and thickness of the sealant applied to the case, sealing plate, and gasket of the electrochemical element. It is an object of the present invention to provide an electrochemical device having a configuration capable of confirming the uniformity of the structure by visual observation or image recognition. Disclosure of the invention
- the present invention provides an element unit in which a positive electrode and a negative electrode are opposed to each other via a separator, an electrolytic solution that comes into contact with the element unit, a metal case that contains the element unit and an electrolytic solution, and the metal
- An electrochemical element comprising a sealing body for sealing an opening of a case, and a sealant disposed between the metal case and the sealant, wherein the sealant is mainly composed of an elastomer, and an organic pigment. And an electrochemical element colored differently from the metal case, the gasket and the sealing body.
- the present invention also provides an element unit in which a positive electrode and a negative electrode are opposed to each other via a separator, an electrolytic solution that comes into contact with the element unit, a metal case for containing the element unit and an electrolytic solution, And a gasket interposed between the metal case and the sealing body, and a sealant is disposed between the gasket and the metal case or the sealing body.
- an electrochemical element containing an organic pigment and being colored differently from the metal case, the gasket, and the sealing body.
- the organic pigment is an organic pigment composed of a cinnamate-based metal complex.
- the sealant mainly composed of an elastomer is colored with an organic pigment, and its color tone is different from that of the metal case and the sealing body, and is preferably different from that of the gasket. You have set. For this reason, in the manufacturing process, when a sealant coating liquid is prepared and applied to form a coating film, there is a difference in the saturation or color tone between each component such as a metal case and the sealant. It is possible to evaluate and judge the application state, and it is possible to suppress the dispersion of the application state. In particular, in the manufacturing process using an image recognition device, it is not only possible to check the application position of the sealant from the position of the colored portion, but also to feed back the recognition result of the application position to the application device, The position can be controlled precisely.
- the sealant of the present invention has a chemical affinity with the elastomer of the main material and is colored with an organic pigment having substantially the same specific gravity, so that the pigment particles are uniformly dispersed. Becomes Therefore, the coating liquid of the sealant of the present invention does not cause sedimentation or separation of the pigment.
- the above-mentioned prior example JP-A-3-37955 has a configuration in which a white powder or a luminescent agent is simply mixed with a sealing agent for asphalt or wax.
- titanium oxide Specific Substance of white powder (T i ⁇ 2), as the light emitting material has made fluorescent substance.
- the specific gravity of the inorganic powder is relatively large (for example, the specific gravity of titanium oxide is 3.8 to 4.2) Therefore, the powder is easy to separate and settle in the sealant. For this reason, the white powder is unevenly distributed in the coating film, and when such a coating film is applied to a battery, it causes a liquid leakage.
- the sealing agent in order to obtain a uniform coating film, it is necessary to constantly mix and agitate the coating solution of the sealing agent to prevent aggregation and precipitation of the white powder, thereby complicating the coating process of the sealing agent. I will.
- the fluorescent substance is soluble in the organic electrolyte. Therefore, the luminescent agent portion in the sealing agent may be dissolved by the reaction with the organic electrolyte, and may not function as the sealing agent.
- the sealant of the present invention is colored with an organic pigment that is uniformly mixed and dispersed with the elastomer as described above, deterioration of the characteristics due to the deterioration of the function of the sealant applied to the element is prevented. I will not invite you.
- the color of the sealant can be selected according to the color tone of the metal case, the sealing body, and the gasket, and the degree of freedom is large.
- the image recognition device introduced in the manufacturing process is affected by the characteristics of the device and the environment, in addition to the color of each component, so it is preferable to select the image recognition device in consideration of each effect. This makes it possible to greatly improve the recognition accuracy of the coating state, that is, the coating position and the film thickness.
- the sealant of the present invention is mainly composed of an elastomer, and is passed through a reflow furnace. Even if it is passed, the sealing agent does not melt, and the hermeticity inside the container of the electrochemical element can be maintained. Furthermore, it can follow the deformation of components due to the application of thermal stress, especially the expansion and contraction of the gasket, thus greatly improving the sealing performance of electrochemical devices.
- the sealant can be applied to a predetermined position on the peripheral portion of the sealing body, the peripheral portion of the inner surface of the case, the gasket, and the like with a uniform film thickness. Also, it is possible to prevent the occurrence of liquid leakage due to the variation in film thickness. Elastomers and organic pigments that form the sealant both have excellent heat resistance and excellent adhesion between the sealant and other components. The sealing performance can be maintained even when the temperature changes and the thermal stress. Therefore, it is possible to obtain an electrochemical device with a reduced probability of liquid leakage.

Can be obtained. Since the sealant of the present invention is mainly composed of an elastomer, it has an adhesive strength as compared with a well-known sealant such as pitch. Therefore, even if the metal case, the sealing body, or the gasket expands and contracts due to a sudden temperature change during mounting by the reflow method, the change can be followed. Therefore, the sealing performance of the element does not deteriorate due to the temperature change, and the liquid leakage can be reliably prevented.
- chloroprene rubber and acrylic rubber containing carbon and hydrogen elements can be used, and preferably butyl rubber, nitrile rubber, isobutylene rubber, butyl rubber, ethylene-propylene rubber, ethylene It is an elastomer selected from the group consisting of propylene-gen-monomer-rubber, alone or as a mixture of two or more. Silicon rubber having a high ratio of silicon and oxygen atoms in the structural formula, ie, a fluorine-containing silicon rubber, is also applicable.
- These elastomers are generally colorless and transparent or white, but can be colored in any color by combining with an organic pigment described later.
- phthalocyanine-based metal complexes such as phthalocyanine blue and phthalocyanine daline are the strongest in the coloring power of organic pigments, so it is possible to reduce the amount of addition to the sealant.
- Organic organic pigments based on ninnin are more advantageous than other organic pigments.

- these compounds have high stability against various types of electrolytes including organic solvents, that is, organic solvent resistance, alkali resistance, and acid resistance.
- organic solvents that is, organic solvent resistance, alkali resistance, and acid resistance.
- specific gravity is around 1.4, which is equivalent to the elastomer (specific gravity of 1.3 to 1.6) which is a main component of the encapsulant of the present invention, an organic pigment is added to the encapsulant. Does not separate when dispersed ⁇ Also, phthalocyanine-based organic pigments are excellent in terms of heat resistance and can exist stably even when exposed to high-temperature environments such as during reflow. Noh.
- Organic pigments are much better than inorganic pigments in terms of dispersibility in elastomers, and there is no partial color unevenness when producing sealants.
- the reasons for the excellent dispersibility are that the specific gravity of the elastomer and that of the organic pigment are almost equal, and that carbon and water, which are characteristic of the organic pigment, are used. This is because the ligands of metal ions composed of silicon and the like are very weakly and chemically associated with the elastomer, which is a structure mainly containing carbon and hydrogen.
- inorganic pigments are generally composed mainly of metals or metal oxides, and have a specific gravity more than twice that of elastomers. Furthermore, because of lack of affinity with the elastomer, pigment sedimentation starts immediately after mixing with the elastomer, resulting in uneven color of the sealant.
- Dyes used as a means of coloring with organic and inorganic pigments are generally unstable to organic electrolytes and can dissolve. Therefore, when the electrochemical element is stored for a long period of time, the contact between the organic electrolyte solution and the dye component in the sealing agent may cause the dissolution of the dye, which may affect the reliability.
- Organic pigments are very stable in organic electrolytes, do not dissolve the pigment components in the encapsulant during long-term storage, and have no effect on the long-term reliability of batteries. Absent.
- the elastomer which is the main component of the sealant, is colorless, transparent, or white. Therefore, as the amount of the organic pigment contained in the sealant increases, the color of the sealant itself increases. Therefore, by setting a large difference between the color of the gasket and the saturation of the colored sealant, the application position of the sealant and the uniformity of the coating can be easily confirmed visually or by image recognition. For example, when milky white resin is used for the gasket, applying a sealing agent that is colored in a dark color, especially black or blue-violet, improves the recognition accuracy of the application state.
- the ratio of the organic pigment in the sealant the recognition accuracy of the applied state is improved by increasing the amount of the organic pigment.
- the amount of the elastomer in the sealant is relatively reduced, and the sealing effect, which is the most important function required of the sealant, is reduced. For this reason, the adhesive performance at the contact surface between the sealing body and the gasket with the polymer is reduced, and the probability of occurrence of liquid leakage is increased. Therefore, the ratio of the organic pigment in the sealant has a suitable range. Specifically, it is preferably about 10 to 30% by weight.

- a solution prepared by dissolving lump butyl rubber with toluene was prepared, and phthalocyanine fine powder was added thereto.
- the coating solution of the sealing agent thus prepared was applied to gasket 3 and a predetermined position of case 1. This application was performed manually, and the application status was visually checked.
- toluene was evaporated to form a butyl rubber coating containing an organic pigment.
- the ratio of the butyl rubber and the pigment in the coating solution was 5% by weight, and the composition ratio of the butyl rubber and the organic pigment was 40% by weight with respect to 60 parts by weight of the butyl rubber. Parts.

- Battery E was manufactured in the same manner as Battery A except that titanium oxide was used as the inorganic pigment instead of phthalocyanine blue, which was the organic pigment of Battery A ( Comparative Example 3).
- a toluene solution in which only butyl rubber is dissolved is applied to a predetermined site, and the toluene is evaporated.
- a battery F made only from the battery was assembled.
- the concentration of butyl rubber in the toluene solution used is 3% by weight.
- the batteries A to C of the obtained examples and the batteries D to F of the comparative examples were passed through a high-frequency heating type reflow furnace and subjected to a high temperature environmental resistance test.
- the temperature profile inside the reflow furnace through which each battery passes was left in an environment of 180 ° C for 2 minutes as a preheating step, followed by a heating step of 180 ° C. After passing through each environment of 0 ° C.
- Batteries A, B, and C are more excellent in the liquid leakage resistance after passing through a reflow furnace than Comparative Battery F, which does not contain a pigment in the sealant. Due to the difference in color saturation between the gasket 3, the case 1, and the sealing plate 2, the colored sealant can be visually inspected for the coating position and the coating state such as spots and rubbing. Can be easily confirmed. For this reason, the sealant layer in the sealing portion is formed uniformly, and the variation thereof is reduced, and the probability of occurrence of liquid leakage is greatly reduced. Although the coloring of the sealant was changed in batteries A to C, there was little difference in the occurrence of liquid leakage depending on the type of organic pigment added to the sealant. The present inventors have also confirmed that there is no difference in the state of occurrence of liquid leakage as long as the type of the organic pigment described in the above embodiment and the ratio of addition to the sealant are used.
- the applied sealant film is colorless and transparent, and it is not necessary to perform the application work while checking the position of the sealant applied and the state of spots and blurring. It is very difficult, and it is also difficult to judge these conditions from the state after application. For this reason, even if the applied sealant has spots or faintness, or is applied to a place deviating from a predetermined position, the state of the sealant cannot be visually checked, and the application of the sealant cannot be performed. The state will vary. And, due to the variation in the application state, batteries in which the sealant is not formed at predetermined positions and film thicknesses are mixed, and it is considered that these batteries leak after passing through the reflow furnace. Conceivable.

- it is an organic electrolyte using one or more solvents, it is stable to elastomers and organic pigments and has no effect on the sealant. It has been confirmed.
- sulfolane has a boiling point of 287 ° C
- 3-methylsulfolane has a boiling point of 276 ° C
- tetraglyme has a boiling point of 275 ° C
- methyloxa Since the boiling point of zolidinone is 270 ° C, vaporization and decomposition of the electrolyte do not occur in an environment below each boiling point. For this reason, even inside the one-furnace furnace with a temperature of up to 250 ° C, the sealant is present in a stable state without deterioration due to heat and decomposition of the electrolyte, and battery characteristics are maintained. And enable implementation by the reflow method.
- the present invention by setting the color of the organic pigment added to the sealant to be different from the color of the component constituting the electrochemical element, when the sealant is applied, Evaluate and judge the state of application from differences in saturation Become.
