When the compound is filmed to a thickness of 0. The electron-conductive carbon fine particles for use in the present invention are not particularly limited, but favorable are fine particles of acetylene black and Ketjen black, gas-phase carbon fiber, graphite fine particles, and the like.
The reasons are as follows: Among these methods, bar-coater coating, casting, and the like are preferable for better control of film thickness. MatWeb is intended for personal, non-commercial 0d202. Table 1 reveals that the secondary batteries in Comparative Examples are not lower in the retention rate from initial capacity at lower rate, but significantly lower in the retention rate from initial capacity at higher rate than those in Examples according to the present invention Examples, suggesting that secondary batteries are more difficult to discharge and recharge rapidly.

The thickness of the film is preferably 0. Anode active material and method of manufacturing the same and lithium secondary battery using the same.
A mixed paste containing the cellulose and electron-conductive carbon fine particles acetylene black, particle diameter: Examples of the ion-permeable compounds for use in the present invention include compounds non-swelling in organic solvent, compounds resistant to exfoliation in a peeling test with organic solvent, compounds resistant to exfoliation in a tape-peeling test hereinafter, all these compounds will be referred to as film-forming compoundsand typical examples thereof are shown below: The film-forming compound is preferably one of the compounds above that is resistant to organic solvent and adheres to the metal foil tightly, because the formed film is dissolved in the organic electrolyte solution that is normally used as the electrolyte solution in lithium-ion battery.
Cathode current collector coated with primer and magnesium secondary battery comprising the same. A mixed paste containing electron-conductive carbon fine particles 3 acetylene black, particle diameter: Then, a polysaccharide polymer cellulose crosslinked with a chitosan pyrrolidone carboxylate salt was made prepared as the ion-permeable compound.
The ratio of respective components, anodic electroactive material: It should be understood based on this disclosure that various other modifications can be made by those in the art based on these illustrated embodiments. A lithium-ion secondary battery was prepared in a similar manner to Example 1, except that the ion-permeable compound used in Example 1 was replaced with a PVA polyvinyl alcohol binder compound vulnerable to exfoliation in tape-peeling testand the retention rate from initial capacity and the internal d0022 were determined under the conditions similar to those in Example 1, and the results are summarized in Tables 1 and 2.
We advise that you only use the original value or one of jks raw conversions in your calculations to minimize rounding error. Current collector for secondary battery, positive electrode for the secondary battery, negative electrode for the secondary battery, the secondary battery, and manufacturing method of them. In this disclosure and during d2002 prosecution of this case, c0202 following abbreviated terminology may be employed: The particle size of the electron-conductive carbon fine particles is not particularly limited, but preferably, approximately 10 to nm.
In addition, these polymers have a smaller average molecular weight at approximately 50, and are not sufficiently adhesive to metal foil.

Typical examples thereof include casting, bar-coater coating, dip coating, printing, and the like. Recently, there is an increasing trend toward application of such a high-performance secondary battery in the fields demanding power such as automobiles, which gave rise to problems not foreseen from conventional smaller batteries.
As described above, a kis current is indispensable for quick discharge and recharge.
A greater amount of current is needed for generation of greater power. Users of our Advanced Search registration required may exclude discontinued materials from search results. A compound resistant to exfoliation in a tape-peeling test, a polysaccharide polymer chitosan crosslinked with acrylonitrile, was prepared as the replacement for the ion-permeable compound used in Example 5.
The anodic material is not particularly limited and examples thereof include graphite-based materials such as graphite, amorphous graphite materials, and oxide materials. Coating solution, electric collector, and method for producing electric collector.
Although it was possible to prepare a secondary battery, the current collector having a film containing carbon uis particles after preparation resulted in significant exfoliation of the current collector surface when it is subjected to the tape-peeling test, suggesting that the secondary battery would not withstand use for an extended period of time even if it had favorable initial characteristics.
A film containing a film-forming compound and carbon fine particles is then formed as the lower layer, while a film containing a binder, carbon fine particles and a cathodic electroactive material as the upper layer.
Data sheets from materials that are no longer available remain in MatWeb to assist users jjis finding replacement materials. The jsi of respective components, cathodic electroactive material: While illustrative embodiments of the invention have been described herein, the present invention is not limited to the various preferred embodiments described herein, but includes any and all embodiments having equivalent elements, modifications, omissions, combinations e.
0d202 addition, it is necessary to use the fine particles in an amount as small as possible for preservation of its battery capacity.
Hereinafter, the method of forming a film containing a cathodic electroactive material will be described in more detail. A secondary-battery current collector comprising an aluminum foil and a film containing an ion-permeable compound and carbon fine particles formed thereon or a secondary-battery current collector comprising an aluminum foil, a film containing an ion-permeable compound and carbon fine particles formed thereon as the lower layer, and a film containing a binder, carbon fine particles and a cathodic electroactive material formed thereon as the upper layer, a production method of the same, and a secondary battery having the current x0202 are provided.
Lithium-ion secondary battery is a high-performance secondary battery and has been used in various applications such as cell-phone, notebook computer and camcorder because of its high energy density, and is expanding its market significantly. In some examples, various embodiments may include overlapping features. Examples of the crosslinking agents for use include acrylamide, acrylonitrile, chitosan pyrrolidone carboxylate salt, hydroxypropylchitosan, and acid anhydrides such as phthalic anhydride, maleic anhydride, trimellitic anhydride, and pyromellitic anhydride, and the like.
Collector and electrode structure, non-aqueous electrolyte cell, electrical double layer capacitor, lithium ion capacitor, or electricity storage component using same. Because d020 solvent is removed by vaporization in the downstream step, only solid matters film-forming compound, carbon fine particles, and cathodic active material remain in the film.
