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.
Because the 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. More specifically, the cathode of common lithium-ion secondary batteries is prepared by immobilizing a cathodic electroactive material such as lithium cobaltate or lithium manganate and electron-conductive carbon fine particles having a current-collecting effect for conveying electrons therefrom thereto on a metal foil.
The shape thereof is preferably non-spherical, and carbon particles having an anisotropic shape, spicular or rod in shape, are more preferable. In the following paragraphs, some preferred embodiments of the invention will be described by way of example and not limitation.

A secondary-battery cathode comprising: The anodic electroactive material used then was graphite; the conductive carbon fine particles, acetylene black; the binder, polyvinylidene fluoride PVDF ; and the solvent, N-methylpyrrolidone NMP.
Thus, the present invention relates to the followings:. Then, the paste was applied on the aluminum foil 1 by casting by using an applicator opening: A current collector for cathode or anode is prepared by forming a carbon fine particles-containing film on an aluminum or copper foil. However, discharge and recharge of conventional lithium-ion secondary batteries at a greater current jiz an inconvenience of drastic deterioration in capacity retention rate of its initial battery capacity when the discharge and recharge are repeated, i.
Examples of the materials showing the properties above include derivatives of polysaccharide polymers crosslinked with an acrylic additive or an acid anhydride, materials derived from chitosan derivatives, and the like. In some examples, various embodiments may include overlapping features.
The ion-permeable compound is not particularly limited, if it is a material allowing permeation of ions including compoundsand examples thereof include crosslinked polymers of cellulose and acrylamide, crosslinked polymers of cellulose and a chitosan pyrrolidone carboxylate salt, and the like.

A secondary battery comprising: Indeed, certain features of the invention may be capable of overcoming certain disadvantages, while still retaining some or all of the features, embodiments, methods, and apparatus disclosed therein. The cathodic electroactive material for use in the present invention is not particularly limited, if it is a material adsorbing and releasing lithium ions. The solvent used was water, and the weight ratio of ion-permeable compound 4: A method of producing a secondary-battery cathode, comprising: Among these methods, bar-coater coating, casting, and the like are preferable for better control of film thickness.
The molecular weight thereof was 35, as determined by GPC. Any one of known materials may be used as the anodic electroactive material for anode.
A mixed paste containing electron-conductive carbon fine particles 3 acetylene black, particle diameter: Accordingly, fine particles having a greater surface area per weight are advantageous. The retention rate from initial capacity and the internal resistance thereof were determined similarly, and the results are summarized in Table 1. A thickness of 0.
These materials may be available by special order, in distribution inventory, or reinstated as an active product. 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.

A lithium-ion secondary battery was prepared in a similar manner to Example 1, except the modifications above. Polyamide, polyamide-imide and the like, which are known as the compounds resistant to organic solvent, are generally, very expensive and not practical.
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. The molecular weight thereof was 40, as determined by GPC. Table 2 also reveals that the secondary batteries in Examples are lower in internal resistance and suitable for quick discharge and recharge.
Then, the paste was applied on the aluminum foil 1 in a similar manner to Example 1 by using an applicator opening: Other objects and advantages of the present invention will be apparent from the following preferred embodiments. A lithium-ion secondary battery was prepared in a similar manner to Example 2, except the modifications above.
Negative electrode for lithium secondary battery, manufacturing method thereof, and lithium secondary battery. Questions or comments about MatWeb? 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.
The metal foil used then is generally an aluminum foil, and, for example, polyvinylidene fluoride PVDF or polytetrafluoroethylene PTFE is used as the binder for immobilizing the cathodic electroactive material and carbon fine particles thereon.
