摘要:
A packaged electrode plate for a secondary battery with a nonaqueous electrolyte comprises: an airtight container having a winding core and a tape pulling-out opening; and a wound tape comprising an electrode plate for a secondary battery with a nonaqueous electrolyte. The wound tape is stored in the airtight container and supported on the winding core thereof. A forward end of the wound tape is pulled out from the tape pulling-out opening of the airtight container, and the tape pulling-out opening is hermetically closed by means of an airtight sealing means which holds the forward end of the wound tape pulled out from the tape pulling-out opening.

An electrode plate for a secondary battery with nonaqueous electrolyte comprises a collector and a coated layer formed on the collector by coating a coating solution at least containing an electrode active material and a binder on the collector and then drying the same, wherein a ratio (b/a) of an amount (b) of a binder existing at a boundary portion of the coated layer on a side opposite to a collector side to an amount (a) of a binder existing at a boundary portion of the coated layer contacting the collector is 0.05 or more and less than 2. The manufacturing method of the electrode plate comprises the step of forming a coated layer having a predetermined thickness by repeating at least two times of coating and drying processes for coating the coating solution, wherein a thickness of a coated layer formed in a second time or more than second time coating and drying processes is increased by an amount in a range of 0.4 to 1.6 time of a thickness of a coated layer already formed in preceding coating and drying processes, or wherein an increased amount in weight per unit area of the coated layer formed in a second time or more than second time coating and drying processes is in a range of 0.6 to 1.6 time of a weight per unit area of a coated layer already formed in preceding coating and drying processes.

A porous coating layer formed on a substrate is impregnated, based on a prescribed pattern, with liquid material having a larger cohesion after solidification thereof than that of the coating layer. The liquid material is solidified to form a solidified material. Then, a portion of the coating layer, which has been impregnated with the solidified material is peeled to expose partially the surface of the substrate on the basis of the prescribed pattern, thereby producing the porous coating layer having the prescribed pattern. An electrode plate for a secondary battery with a nonaqueous electrolyte can be produced by utilizing the above-mentioned production process.

The present invention provides a coating composition for a negative electrode-active material layer, which comprises an active material for a negative electrode, and two or more rubber base binders selected from rubber base binders having a glass transition temperature of 0 to 120° C. The present invention also provides a negative electrode plate, a method for producing the same and a secondary battery with a nonaqueous electrolyte using the above coating composition.
摘要:
In a slide fastener, a fastener tape is woven with a single-woven structure, and in the fastener tape, a double-woven region woven with a double-woven structure is formed along a tape longitudinal direction. An inner single-woven region and an outer single-woven region of the single-woven structure are formed at a tape inner edge side and a tape outer edge side of the double-woven region. Thus, even if the fastener tape makes contact with ridge line portions on a lower blade side of the slider when the slider is slid, weft yarns arranged in the double-woven region are less likely to be cut.

Provided is a surface film for a polarizing plate in which transparent patterns having a non-visible light reflective regularity are printed on a surface of a substrate and in which a reflection preventive layer or an antiglare layer is formed thereon or on a back side thereof, wherein an ink constituting the above transparent patterns contains a material reflecting a non-visible light. Capable of being provided is a surface film which can suitably be used for providing additional informations to an image display medium in such a manner that data are input by handwriting directly on a display device and in which the function described above is built-in from the beginning without making it necessary for the user to stick later a sheet having the above function.

(1) The maximum thickness in an area inside by 20 mm from an edge portion of the active material layer is not more than the sum of an average thickness of the active material layer and 10 &mgr;m. (2) In an inclined portion of the peripheral edge portion of the active material layer, an area in which the thickness of the active material layer is not less than 1 &mgr;m and less than an average thickness of the active material layer has a width of not more than 1 mm. (3) An absolute value of a positional shifting of an actually formed pattern with respect to a true boundary line of a predetermined pattern is not more than 1 mm. (4) The active material layers are formed in a plane symmetry to front and back surfaces of the collector, and an absolute value in the positional shifting between the patterns formed on front and back side surfaces of the collector is not more than 1 mm.
