A secondary battery comprising: In Example 3, the aluminum foil material A used in Example 2 was replaced with an aluminum foil A, and a compound resistant to exfoliation in a peeling test with organic jie, i. However, discharge and recharge of conventional jix secondary batteries at a greater current cause an inconvenience of drastic deterioration in capacity retention rate of its initial battery capacity when the discharge and recharge are repeated, i.
Polyacrylamide cross-linked with a polysaccharide resin as electrophoretic gel medium.
Please contact us at webmaster matweb. As described above, a greater current is indispensable for quick discharge and recharge.
Collector, electrode structure, non-aqueous electrolyte cell, and electricity storage component. Electrode material, electrode material manufacturing method, electrode, and secondary battery. Lithium cobaltate or lithium manganate is generally used as the cathodic electroactive material and graphite as the anode in smaller lithium ion batteries among them.

The jid characteristics of the lithium-ion secondary battery thus obtained were determined. On the other hand, there are polymers having an average molecular weight of 50, or more such as the PVDF, PTFE, jiz others described above, and these polymers are sufficiently adhesive to the metal foil but not resistant to organic solvent as, they swell in the organic solvent. Other objects and advantages of the present invention will be apparent from the following preferred embodiments.
The limitations in the claims are to be interpreted broadly based on the language employed in the claims and not limited to examples described in the present specification or during the prosecution of the application, which examples are to be construed as non-exclusive. Comparative Example 3 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 resistance were determined under the conditions similar to those in Example 1, and the results are summarized in Tables 1 and 2.
No vendors are listed for this material. These materials may be available by special order, in distribution inventory, or reinstated as an active product. A lithium-ion secondary battery was prepared in a similar manner to Example 2, except the modifications above.
Example 3 In Example 3, the aluminum foil material A used in Example 2 was replaced with an aluminum foil A, and a compound resistant to exfoliation in a peeling test with organic solvent, i. Subscribe to Premium Services Searches: The invention claimed is: A method of producing a secondary-battery anode, comprising: In addition, the cathodic electroactive material was replaced with an olivine compound LiFePO 4. Japanese R0202 Patent Publication No.
A thickness of 0. Hereinafter, the present invention will be described specifically with reference to Examples and Comparative Examples, but it should be understood that the present invention is not restricted by the following Examples. Although it was possible to prepare a secondary battery, the current collector having a film containing carbon fine particles after preparation resulted in significant exfoliation when the surface of the current collector is rubbed with an NMP-impregnated cloth, suggesting that the secondary battery would not withstand use for e0202 extended period of time even if it had favorable initial characteristics.
Metal foil, iis foil manufacturing method and method for manufacturing electrode using the same. Because the solvent is removed by vaporization in jie downstream step, only solid matters film-forming compound, carbon fine particles, and cathodic active material remain in the film.

Thus, the present invention relates to the followings:. Cathode current collector coated with primer and magnesium secondary battery comprising the same. Users requiring more precise data for scientific or engineering calculations can click on the property value to see the original value as well as raw conversions to equivalent units.
A lithium-ion secondary battery was then prepared in the step similar to Example 1, by connecting the separator and the cathode formed on aluminum foil used in Example 1 and impregnating the composite with the organic electrolyte solution.
In the following paragraphs, some preferred embodiments s0202 the invention will be described by way of example and not limitation. The compound was filmed to a thickness of 0. TECHNICAL FIELD The present invention relates to a lithium ion secondary-battery current collector, a secondary-battery cathode, a secondary-battery anode, a mis battery and methods of producing the same, and also to a high-performance material giving a lithium-ion secondary battery superior in quick-recharge s0202.
The cathodic electroactive material used then was lithium cobaltate; the conductive carbon fine particles, acetylene black; the binder, polyvinylidene fluoride PVDF jiz and the solvent, N-methylpyrrolidone NMP. A lithium-ion secondary battery was prepared in a similar manner to Example 1, except the modifications above.
