After the application (hand brushing), it was alleged that a solid electrolyte thin film with extremely low air permeability was obtained after drying and firing. Issues that the invention seeks to solve
- the membrane obtained by this method is basically porous. Therefore, in order to eliminate air permeability, it is necessary to form a film having a certain thickness. Alternatively, the holes must be sealed off after spraying, as in the technique described in (1) above.
- the solid electrolyte thin film disclosed as an example in Japanese Patent Application Laid-Open No. 193,065 has a thickness of 15 Om, and the development of this type of film has been developed. It is quite thick compared to the target of 10 ⁇ 50 ⁇ .

- the film thickness is 10 to 5 ⁇ :, and at the membrane surface, more than 80% of the total surface area is the crystal grain size of 6 to 18 It is characterized by being occupied by crystals of / xm.
- the film When the half width is in the above range, the film has good crystallinity and uniform firing proceeds.Therefore, there are no cracks or continuous pores between the crystal grains. A dense solid electrolyte thin film can be obtained.
- the method for producing a solid electrolyte thin film of the present invention is a method for producing a thin film comprising a sintered body of a solid electrolyte powder; A particle size adjusting step for adjusting the particle size to 0.1 to 5.0 um; a solvent containing 100 to 80 wt% of the non-volatile solvent; 100 parts of the solvent; 1 to: 10 parts, 0.1 to 4 parts of dispersant, 0.1 to 4 parts of defoamer to adjust slurry solution, 100 weight of this slurry solution And a slurry adjusting step of obtaining a slurry by mixing 5 to 40 parts by weight of the solid electrolyte powder whose particle size has been adjusted as described above, and a slurry adjusting step of obtaining the slurry. And (c) a step of applying the composition to a substrate, wherein the slurry composition is adjusted so that the slurry has a viscosity of 1 to 500 cps.
- the solid electrolyte in the production method of the present invention is not limited to a specific substance.
- Y 2 0 3 stabilized Z r 0 material such as 2 (YSZ).
- Y 2 0 3 including Yuryou in YSZ is, good or was rather the Ri Oh at 3 ⁇ 2 0 mo 1%, good Ri rather than the good or the Ru Oh in 8 ⁇ 1 2 mol%. The reason for this is that this range is superior in terms of ion conductivity.
- the particle size of the solid electrolyte powder is preferably 0.1 to 5.0 Om, and more preferably 0.2 to 0.4 m.
- the film thickness for obtaining a dense (gas-tight) film is several tens to Although a few hundred meters is required, when a raw material having a narrow particle size distribution of 0.2 to 0.4 mm is used, a dense film having a thickness of several to several tens ⁇ can be formed. .
- a classifier of the type such as air ratio.
- the feature of the solvent of the slurry solution in the present invention is that it contains 10 to 8 O wt% of a non-volatile solvent, more preferably 15 to 40 ⁇ ⁇ %. is there .
- the action of this non-volatile solvent is to make slurry, to suppress the viscosity change of slurry during storage, and to form a film using this slurry (for example, If the This is to suppress the occurrence of cracks caused by drying after drying.
- the degree of refractoryness is desirably 1 or less, for example, when the degree of volatility of butyric acetate is 100.
- ⁇ -terbineol As an example of a non-volatile solvent, ⁇ -terbineol can be mentioned.
- the reason that the content of the volatile solvent is limited to 10 to 80 wt% is that at low concentrations (less than 1 Owt%), the film after the film formation (datesbing) is not formed. This is because dry black is likely to be produced, and if the concentration is too low (more than 80 wt%), the dispersion of the powder becomes poor.
- the content of the non-volatile solvent is more preferably 15 to 40 wt%. This is because, within this range, the dispersibility of the powder in the slurry and the drying condition after the datesbing have the best characteristic balance.
- the action of the solvent contained in the slurry solution other than the volatile solvent is to improve the dispersibility and defoaming property of the powder.
- Ethyl alcohol is preferred as an example of such a solvent.
- the effect of the solder contained in the slurry solution of the present invention is to improve the coating property (adhesion) of the powder to the substrate. is there .
- the reason that the amount of binder is limited to 0.1 to 10 parts with respect to 100 parts of the solvent is that if the concentration is low (less than 0.1 wt%), the coating is not effective. This is because if the dispersibility of the powder is low and the concentration is too high (more than 10 wt%), the dispersibility of the powder becomes poor.
- a binder ethylcellulose is preferable.
- the action of the dispersant contained in the slurry solution of the present invention is to improve the dispersibility of the powder.
- the reason that the amount of the dispersant is limited to 0.1 to 4 parts with respect to 100 parts of the solvent is that if the concentration is low (less than 0.1 wt%), the dispersibility is low and the concentration is high. If the temperature is higher than 4 wt%, slurry metamorphosis is likely to occur.
- a specific example of the dispersant is a polyoxyethylene carboxylic acid ester.
- the antifoaming agent contained in the slurry solution of the present invention works to eliminate bubbles in the slurry.
- the reason that the amount of defoamer is limited to 0.1 to 4 parts with respect to 100 parts of the solvent is that if it is less than that, the effect is not so much expected, and it cannot be expected. Beyond that, the metamorphosis of the binder in the slurry is likely to occur.
- Sorbitan Sessorelete is mentioned.
- the method of applying the slurry to the substrate in the manufacturing method of the present invention is not particularly limited. Dates, sprays, brushes, etc. Of these, the datesving method is preferred. It is easy, mass-produced, and low-cost.
- the date swinging method is not limited to the ordinary dipping method in which a substrate is immersed in a slurry in the air, but also in a pressurized gas or vacuum. You can adopt a method of performing diving. In that case, the number of dates bending can be selected according to the required film thickness and the slurry composition to be used.
- the viscosity of the slurry is adjusted to 1 to 500 cps, more preferably 1 to LOO cps. is there .
- the reason the lower limit is limited to 1 cps is to prevent the penetration of the substrate (porous) hesserie.
- the reason the upper limit is limited to 500 cps is to prevent cracking during drying after slurry coating.
