As shown in FIG. Thereupon, the jks in melting point between the non-woven fabric and the ultra-microfibers should be considered so that the ultra-microfibers are not melted. The Zehntner ZOL Online-Glossmeter is a tailored gloss-measuring system for industrial areas for contactless online measurement of all gloss ranges from matt to high gloss up to 2’GU. Injection of the nonaqueous electrolyte is suitably carried out using a vacuum injection method but is not limited thereto.

The present invention has been accomplished as the results of extensive studies to achieve the above object. The non-woven fabric may contain various other fibers in addition to the fibers of the above-exemplified thermoplastic materials. No particular limitation is imposed on the shape of the lithium-ion secondary battery thus produced, which may be of a flattened or button shape such as a cylindrical or square shape. No particular limitation is imposed on the method for producing a lithium-ion battery comprising the separator of the present invention.
Standard JIS Z 8741
Among these materials, those containing polypropylene as the main component are preferably used. Randomly, 10 photos from the photos taken were selected to measure the diameters of all the fibers in the 10 photos and calculate the average of the diameters thereby obtaining the average diameter of the fibers.
The film portion does not permeate ions and thus lowers the first discharge capacity. Non-aqueous electrolyte battery separator and 8714 non-aqueous electrolyte battery. Alternatively, in the case where the kis and the electrode are bonded well, the battery can be produced without through the thermal compression bond process.
The lithium-ion secondary battery separator according to claim 5wherein the core component and sheath component of the core-in-sheath type composite fibers are polypropylene and polyethylene, respectively.
Photos of the surface of a fiber assembly thus produced was taken with an electron scanning microscope Jjis manufactured by Hitachi, Ltd. The core-in-sheath type composite fibers of polyolefins are preferably used in combination with various fibers formed from the above-exemplified jks materials other than polyolefins.
The present invention relates to separators that are excellent in electrolyte retainability, rate characteristics, and safety and can lower the internal resistance of an electrochemical device and extend the working life thereof for lithium-ion secondary batteries.
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. PC Software Data logging software.
Jjis foil was punched out to be 15 mm in diameter and then pressed thereby producing an anode. The separator is thin and does not short-circuit and has excellent electrolyte retainability and rate characteristics. The present invention has an object to provide a separator for a lithium-ion secondary battery that solves the problems of the conventional art, i.
In the present invention, the non-woven fabric is preferably 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 non-woven fabric of the present invention produced as described above is enhanced in laminate strength and small in diameter of pores between the fibers because the fibers partially fused to one another.
Any active material used in a so-called 4 V class lithium-ion secondary battery may be used. The average jiw the measurement results at a total of the 10 sites was defined as the glossiness of the non-woven fabric.
JIS Z – Zehntner GmbH
A paste of cathode material was prepared by mixing homogeneously The glossiness can be arbitrarily adjusted by the temperature and pressure at which the heat pressing is carried out. Popular Accessories Data logging software. When the non-woven fabric and the ultra-microfibers are combined, the ultra-microfibers may have been included in the non-woven fabric at the time of production thereof beforehand and then may be subjected to a heat pressing to make a single piece of non-woven fabric.
However, this type of separator has an extremely small pore size that is on the order of submicron or smaller and thus when the viscosity of an electrolyte is high, has had a problem that the electrolyte is unlikely to permeate into the separator and the efficiency of the battery assembly becomes poor. Battery Requires power supply. The ultra-microfibers used in the present invention may be produced by various methods such as Melt-Blown method, electrospinning and melt-electrospinning methods.
When the non-woven fabric contains various other fibers, the weight ratio of the fibers of a thermoplastic jls and the various other fibers is preferably from s
