Then, the paste was applied on the aluminum foil 1 by casting by using an applicator opening: More specifically, it is currently almost impossible to discharge and recharge a battery at 20 C i. 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 jks thereon as the upper layer, a production method of the same, and a secondary battery having the current collector are provided.

Such characteristics of the secondary-battery current collector and others according to the invention expand application ijs the devices carrying a secondary battery and the range of industrial applications thereof.

Information provided by Kleerdex Company. Among these methods, bar-coater coating, casting, and the like are preferable for better control of film thickness. Any one of known materials may be used as the anodic d202 material for anode. 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.

Jix 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.

A film containing an anodic electroactive material can also be prepared similarly to the film above, by replacing the aluminum foil and the cathodic electroactive material in the description below respectively with a copper foil and an anodic electroactive material. Recently, there is an increasing trend toward application of such a high-performance secondary battery in the d002 demanding power such as automobiles, which gave rise to problems not foreseen from conventional smaller batteries.

The present invention provides a secondary-battery current collector, a method of producing a secondary-battery current collector, and a secondary battery having d00202 current collector.

Although it was possible to prepare a 0d202 battery, the current collector having a film containing carbon fine particles after preparation resulted in significant exfoliation of the current collector surface when it jus subjected to the tape-peeling test, suggesting that the secondary battery would not withstand use for nis extended period of time even if it had favorable initial characteristics. Polyamide, polyamide-imide and the like, which are known as the compounds jix to organic solvent, are generally, very expensive and not practical.

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 e0202 a chitosan pyrrolidone carboxylate salt, and the like. EXAMPLES 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.

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.

Further, a separatfor and an anode formed on a copper foil were connected, and the composite was impregnated with an organic electrolyte solution, to give a lithium-ion secondary battery. The current collector according to the present invention may have two films, upper and jia layers, on the aluminum foil. The carbon fine particles used were gas-phase carbon fiber registered trade name: Example nis 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.

In the following paragraphs, some preferred embodiments of the invention will be described by way of example and not limitation. The binder contained in the upper layer is not particularly limited, if it can immobilize the particles, and may additionally contain a film-forming compound such as a polysaccharide polymer crosslinked with an acrylic additive or a commonly-used compound, for jls polyvinylidene fluoride PVDF or polytetrafluoroethylene PTFE.

Hereinafter, the present invention will be described specifically with reference to Examples d00202 Comparative Examples, but it should be understood that the ijs invention is not restricted by the following Examples. The molecular weight thereof was 31, as determined by GPC. Please read our License Agreement regarding materials data and our Privacy Policy. The limitations in the claims are to be interpreted broadly nis 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.

In this disclosure and during the prosecution of d202 case, the following abbreviated terminology may be employed: Evaluation of the performance of the secondary-battery current collector according to the present invention as battery can performed by preparing an electrode with the current collector and forming a secondary battery together with a known separator and organic electrolyte solution.

Then, a polysaccharide polymer cellulose crosslinked with a chitosan pyrrolidone carboxylate salt was made prepared as the ion-permeable compound. Results are summarized in Table 1. In the present invention, the method of preparing the film containing a film-forming compound and carbon fine particles is not particularly limited, and any one of known methods may be used. 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 copper foil is also similar, and a rolled copper foil or an electrolytic copper foil is used favorably. The composition of the film is adjusted in jid step of forming a paste for the film. 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 his 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: A lithium-ion secondary battery was prepared in a similar manner to Example 1, except the modifications above.

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. 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.
