The foil was punched out to be 15 mm in diameter and pressed thereby producing a cathode.

Therefore, the non-woven fabric is inadequate for the use in a lithium-ion secondary battery. A separator with a higher porosity provides a battery with better characteristics.

The present a has been accomplished as the results of extensive studies to achieve the above object. Each value in the examples was determined with the following method. Int’ l Search Report issued on Jul. The non-woven fabric may contain various other fibers in addition to the fibers of the above-exemplified thermoplastic materials.

The material of the ultra-microfiber used in the present invention may be of any type if it can iis microfined, such as various polyolefins, polyesters, polyvinyl alcohols, various fluororesins, polyimides, polyphenylene sulfides. The concentration of the lithium salt dissolved in the solvent is preferably within the range of 0. Therefore, in the case where the ultra-microfibers and the non-woven fabric are combined, the range of the most appropriate glossiness is not affected by ratio of short-circuit and defined with the first charge and uis capacity.

Separator furnished with porous coating layer, method of manufacturing same, and electrochemical device furnished therewith. With regard kis the zz limit glossiness, the glossiness which is low even after being heat-pressed indicates that the fibers do not fuse by heat-pressing and thus the non-woven fabric has a problem in strength.

Specifically, examples of the cathode collector include aluminum, stainless steel and the like and examples of the anode collector include copper, nickel, stainless steel and the like. The reason for using the glossiness of the non-woven fabric alone containing no ultra-microfiber is that as described above, when ultra-microfibers are contained, they scatter light and thus the glossiness of the original non-woven fabric fiber cannot be measured.

Reporting software Data logging software.

The lithium-ion secondary battery separator according to claim 12wherein the thermoplastic material is at least one type of thermoplastic material selected from the group consisting of polyolefins, polyesters, polyamides, polyimides, polyacrylonitriles and polyvinyl alcohols.

Bonding of the separator and ji electrode is mainly carried out with a thermal compression bond method, which may be carried out in a dry state where the nonaqueous electrolyte solution is not contained or jsi wet state where the nonaqueous electrolyte solution is contained.

Overview Your Benefits Your Benefits. Among these materials, those containing polypropylene as the main component are preferably used. In the present invention, polyolefins such as polyethylene PEpolypropylene PP and the like are preferably used, and composite fibers such as core-in-sheath type composite fibers core: If the jie constituting the ultra-microfiber has a lower melting point than the thermoplastic material, the microfiber would melt jiis the thermoplastic material melts.

However, if the conventional non-woven fabric is made too thin, it may cause a cathode and an anode jid short-circuit. The ultra-microfiber may be a continuous fiber or a short fiber if it can be fusion-fixed to the non-woven fabric by heat pressing. Examples include various thermoplastic materials that are polyolefins such as polyethylene, polypropylene and polystyrene, polyesters such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate and polybutylene naphthalate, polyamides, polyimides, polyacrylonitriles and polyvinyl alcohols.

This application is a Section of International Application No. A non-woven fabric that is thick and large in volume would have a problem that it produces film portions when being heat-pressed and thus deteriorates the battery characteristics.

The lithium-ion secondary battery separator according to claim 12wherein the non-woven fabric is formed from core-in-sheath type composite fibers containing a thermoplastic material as the sheath component or the core-in-sheath type composite fibers and other fibers of thermoplastic materials.

The composite fiber is not limited to the core-in-sheath type, and thus side-by-side type and segmented type composite fibers are also preferably used.

Alternatively, the assembly may be impregnated with the nonaqueous electrolyte before being put in the exterior package.

Whereas, the fabric is made thick, it can prevent a cathode and an anode from short-circuiting but has a drawback that the energy density is decreased. Memory Connects to computer.

Examples of the carbon material include those produced by sintering organic polymers such as polyacrylonitrile, phenol resin, phenol novolak resin, cellulose, artificial graphite and natural graphite.

Any conventional 87741 for producing a lithium-ion secondary battery may be employed.

For a film-armored battery with an exterior that is a pack of an aluminum laminated film, the electrode and the separator are preferably bonded to each other to be integrated. Measuring Geometries dual angle: The lithium-ion secondary battery comprises an anode, a cathode, a separator, a solvent and a nonaqueous electrolyte.

Display Connects to computer. Measuring Accuracy 0 – GU: Advantageous Effect of Invention The lithium-ion secondary battery separator of the present invention is thin and safe because it is composed of ultra-microfibers and it does not short-circuit in spite of being high in porosity and also excellent in electrolyte retainability and rate characteristics.
