[Field of Application of the Invention] The present invention relates to a battery sealed with a sealing material, and more particularly to a battery sealed with a sealing material made of an isobutylene polymer containing inorganic fine particles. [Prior art and its problems] In so-called alkaline batteries that use alkaline electrolytes, the use of various sealing materials has been proposed due to the creep characteristics peculiar to alkaline aqueous solutions such as sodium hydroxide and potassium hydroxide. There is. For example, Japanese Patent Publication No. 46-16449 discloses a technique for sealing a coating material mainly made of a copolymer of n-butylene and isobutylene into the gap between openings in an alkaline battery that is sealed with a synthetic rubber gasket and a sealing lid. is disclosed. Further, in JP-A-55-59655, polyisobutylene is applied as a sealing material for lithium batteries using organic electrolytes. However, these copolymers of n-butylene and isobutylene, polyisobutylene, etc. do not necessarily have sufficient leakage resistance, and further improvements have been desired. The present invention has been made to solve the problems of the prior art described above, and an object of the present invention is to provide a battery with good leakage resistance. [Configuration of the Invention] In order to achieve the above-mentioned object, the battery of the present invention has an average molecular weight of 1 to 20% by weight of inorganic fine particles.
It is characterized in that the gap between the battery sealing parts is sealed with a sealing material made of a polymer mainly composed of isobutylene having a molecular weight of 700 to 10,000. Hereinafter, the present invention will be explained in more detail based on the accompanying drawings. FIG. 1 shows a sealed portion of a battery according to an embodiment of the present invention. In the battery shown in the figure, a power generating element with a nickel hydroxide anode and a cadmium cathode is housed in a battery case 1, which also serves as an iron cathode terminal, and an appropriate amount of electrolyte consisting of a 30% potassium hydroxide aqueous solution is injected. ing. Then, as with a normal battery, gasket 2
The opening of the battery case 1 is sealed by a sealing plate 3. A sealing material 4, which is a feature of the present invention, is sealed in a gap 5 in a sealing part of a battery. Since the sealing material 4 has appropriate fluidity, the gap 5 can be sealed by any filling method such as coating, dipping, brushing, or injection. Incidentally, the gap between the sealing portion of the present invention includes the gap between the gasket 2 and the electric plate (FIG. 2) as the case may be. The sealing material 4 is a polymer formed by polymerizing isobutylene as a main monomer, such as an isobutylene homopolymer or a copolymer of isobutylene and n-butene. These are easily available under the trade names of Nippon Petrochemicals Co., Ltd., such as Nippon Oil Polybutene and Tetrax. Moreover, the average molecular weight is preferably 700 to 10,000. If it is less than 700, the sealing performance is insufficient due to low viscosity. Moreover, if the average molecular weight exceeds 10,000, the viscosity becomes too high and handling operations such as coating become difficult, which is not preferable. The present invention is characterized in that 1 to 20% by weight of inorganic fine particles are mixed with the above polymer. Inorganic fine particles used in the present invention include calcium carbonate, magnesium carbonate, calcium sulfate,
Various rubber or plastic inorganic fillers can be used, such as barium sulfate, clay, talc, kaolin, and the like. However, preferred inorganic fine particles are silica fine particles or organic bentonite. Examples of the silica include finely ground silica, precipitated silica, surface-treated hydrophobic silica, and pyrolytic silica. Organic bentonite refers to organically modified bentonite in which an exchangeable base in bentonite is ion-exchanged with a cation, for example, an appropriate cation such as octadecyl ammonium salt. By adding the above-mentioned inorganic fine particles to the isobutylene polymer, the so-called flow phenomenon of the isobutylene polymer can be prevented, thereby significantly improving the leakage resistance. In order to improve leakage resistance, the particle size of the inorganic fine particles is preferably small. However, particles that are too fine are not preferred because the viscosity increases and the mixed polymer becomes difficult to handle. Therefore, in practical terms, the average particle size is 1.0μ or less, preferably 0.1μ.
The following inorganic particles are suitable. Note that it is necessary to select the above-mentioned inorganic particles that are stable even when they come into contact with the electrolyte in the battery, such as an alkaline solution or an organic electrolyte. However, since ordinary inorganic fine particles are stable in the above-mentioned electrolytic solution, there is no need to pay such special attention. The mixture of isobutylene polymer and inorganic fine particles is
An appropriate mixing method may be used, for example, a method of mixing using a mixer, a Banbury mixer, an extruder, or the like. As described above, the present invention is applicable to a battery including a battery case, a power generation element housed in the case, and an opening of the battery case sealed, and particularly to alkaline batteries, or dimethoxyethane, propylene carbonate, tetrahydrofuran. It is suitable for batteries called lithium batteries and manganese batteries that use approach polar solvents such as. [Examples and Comparative Examples] The present invention will be specifically described below based on Examples and Comparative Examples. A battery according to the present invention having the structure shown in FIG. 1 (Example) and a battery using a conventional sealing material (Comparative Example) were manufactured and compared. The fabricated battery is AA type (size: diameter 25mm, height
50mm, 1.5Ah), 25 pieces each. These batteries were repeatedly charged and discharged in the usual manner and then stored in an atmosphere at a temperature of 40° C. and a humidity of 95%. Thereafter, the state of leakage from the sealing part was observed.
The results are shown in Table 1 as the number of batteries that leaked.

[Effects of the Invention] As explained above, since the sealing material used in the present invention has little so-called cold flow, which is a property unique to isobutylene polymers, the battery of the present invention has leakage resistance even during long-term storage. is good. Further, since this sealing material is also inert to alkaline electrolyte, the battery of the present invention has good leakage resistance even when using alkaline electrolyte. Furthermore, since the sealing material used in the present invention has an appropriate viscosity, handling operations such as injection and coating are easy, and therefore, the battery of the present invention is easy to manufacture.
