Claims
- 1. A mixer for mixing a mixture of an ion-conducting polymer and/or an ion-conducting polymer raw material with a powdered substance and for coating the ion-conducting polymer on the powdered substance, comprising:
a container, which holds the mixture inside, and at least one main blade, which faces with an inner bottom surface of the container and rotates relative to the inner bottom surface so as to press-slide the mixture between said lower surface of said main blade and said inner bottom surface of the container, wherein an area ratio of said lower surface of the main blade relative to said inner bottom surface of the container is 5 to 70 percent.
- 2. The mixer according to claim 1, wherein
said area ratio is 10 to 70 percent.
- 3. The mixer according to claim 1, wherein
said area ratio is 15 to 70 percent.
- 4. The mixer according to claim 1, wherein
a gap exists between said lower surface of the main blade and said inner bottom surface of the container.
- 5. The mixer according to claim 4, wherein said gap is constant.
- 6. The mixer according to claim 4, wherein
said gap distance from said lower surface of the main blade to said inner bottom surface of the container is 0.1 to 15 mm.
- 7. The mixer according to claim 4, wherein
said gap distance from said lower surface of the main blade to said inner bottom surface of the container is 0.3 to 5.0 mm.
- 8. The mixer according to claim 4, wherein
said gap distance from said lower surface of the main blade to said inner bottom surface of the container is 0.5 to 3.0 mm.
- 9. The mixer according to claim 1, further comprising
a scraping member for removing the mixture adhered to the lateral surface of said container.
- 10. The mixer according to claim 9, wherein
said scraping member is disposed on said main blade while facing a lateral surface of said container.
- 11. The mixer according to claim 1, wherein
said main blade is disc-shape.
- 12. The mixer according to claim 11, wherein
said disc-shaped main blade has at least one through hole.
- 13. The mixer according to claim 11, wherein
said disc-shaped main blade has at least one notched groove.
- 14. The mixer according to claim 1, wherein
said main blade is a wide plate blade.
- 15. The mixer according to claim 1, wherein
an action of reversing the rotational direction of said main blade is repeated.
- 16. The mixer according to claim 1, wherein
said inner bottom surface has a base portion around the lowest part and a slope surface extending upward from said base portion; and said main blade is positioned above and pivots around said base portion.
- 17. The mixer according to claim 1, wherein
an angle of a surface in the motion direction of said main blade relative to said inner bottom surface of the container is an acute angle.
- 18. The mixer according to claim 1, wherein
a surface opposite to the motion direction of said main blade is almost perpendicular to the inner bottom surface of the container.
- 19. The mixer according to claim 1, wherein
an angle of a surface opposite to the motion direction of said main blade relative to the inner bottom surface of the container is an obtuse angle.
- 20. The mixer according to claim 1, further comprising
a dispersion blade in the container.
- 21. A method for coating an ion-conducting polymer or a the ion-conducting polymer raw material on a powdered substance, comprising steps of:
introducing a mixture of the ion-conducting polymer or ion-conducting polymer raw material with the powdered substance in a container; introducing a portion of the mixture in a gap between an inner bottom surface of the container and a lower surface of a blade, where the area ratio of said lower surface of the blade relative to said inner bottom surface of the container is 5 to 70 percent; and press-sliding the mixture in said gap so as to make the ion-conducting polymer or ion-conducting polymer raw material adhere to a powdered substance.
- 22. The method according to claim 21, further comprising steps of:
press-sliding the mixture in said gap between the inner bottom surface of the container and the lower surface of the main blade; and circulating said mixture to go up and down within the container to repeatedly press-slide the mixture.
- 23. The method according to claim 21, wherein
a solvent is added to the mixture.
- 24. The method according to claim 21, wherein
introducing the mixture in a container; press-sliding the mixture by the main blade against the inner bottom surface of the container; and dispersing the mixture by a dispersion blade.
- 25. The method according to claim 21, wherein
said main blade initially rotates in low speed in order to conduct press-sliding.
- 26. The method according to claim 21, wherein
said container is subject to degassing when wetting of the mixture becomes about half of the surface area.
