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 jos tape-peeling testand the retention rate from initial capacity and the internal resistance were determined under the conditions dd0202 to those in Example 1, and the results are summarized in Tables 1 and 2.

In some examples, various embodiments may include overlapping features.

A lithium-ion secondary battery was then prepared by connecting a separator and an anode current d0022 formed on a copper foil and impregnating the composite with an organic electrolyte solution in the step, jiw a similar manner to Example 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.

Among other potential advantages, some embodiments can provide a current collector for lithium secondary battery permitting quick discharge and recharge and having a higher retention rate of initial battery capacity at a higher rate at a greater currentand a secondary battery using the same.

Metal foil, metal foil manufacturing method and method for manufacturing electrode using the same. The contact area between the aluminum foil and the cathodic electroactive material is preferably larger during charge, because the electrons supplied from outside should be conducted via the aluminum foil to the cathodic electroactive material.

These materials may be available by special order, in distribution inventory, or reinstated as an active product.

A greater amount of current is needed for generation of greater power. The molecular weight of the compound was 22, as determined by GPC. 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.

Thus, the present invention relates to the followings: A lithium-ion secondary battery was prepared in a similar manner to Example 1, except the modifications above. Alternatively, the performance of the secondary battery according to the present invention can be evaluated, as it is installed in a vehicle such as automobile or bicycle or an electric power tool e. 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 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.

Subscribe to Premium Services Searches: 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. US USB2 en A smaller measured value indicates better quick-recharge characteristics.

The description herein of advantages and disadvantages of various features, embodiments, methods, and apparatus disclosed in other publications is in no way intended to limit the present invention. Example 4 In Example 4, the ion-permeable compound used in Example 1 was replaced with a compound non-swelling in NMP, a polysaccharide polymer chitosan crosslinked with trimellitic anhydride, and NMP was used as the solvent.

Hereinafter, the method of forming a film containing a cathodic electroactive material will be described in more detail. However, discharge and recharge of conventional lithium-ion 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. 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.

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. M Year of fee payment: Then, the paste was applied on the aluminum foil 1 in a similar manner to Example 1 by using an applicator opening: 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.

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.

The molecular weight thereof was 26, as determined by GPC.

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. For that reason, use of electron-conductive carbon fine particles having an anisotropic shape is desirable. Table 2 also reveals that the secondary batteries in Examples are lower in internal resistance and suitable for quick discharge and recharge. Negative electrode for lithium secondary battery, manufacturing method thereof, and lithium secondary battery.

This application claims priority to Japanese Patent Application No. A mixed paste containing the cellulose and electron-conductive carbon fine particles acetylene black, particle diameter: Recharge of the battery should be shortened by using a greater current, because a longer recharge period results in elongation of the period when the battery cannot be used.

A mixed paste containing electron-conductive carbon fine particles 3 acetylene black, particle diameter: Collector and electrode structure, non-aqueous electrolyte cell, electrical double layer capacitor, lithium ion capacitor, or electricity storage component using same. Typical examples thereof include casting, bar-coater coating, dip coating, printing, and the like. Japanese Unexamined Patent Publication No. The results are summarized in Table 2.

A current collector for cathode or anode is prepared by forming a carbon fine particles-containing film on an aluminum or copper foil.

We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. Electrode material, electrode material manufacturing method, electrode, and secondary battery. Conductive composition for coating a current collector for a battery or an electrical double layer capacitor, current collector for battery or electrical double layer capacitor, battery, and electrical double layer capacitor.

The cathodic electroactive material used then was lithium cobaltate; the conductive carbon fine particles, acetylene black; the binder, polyvinylidene fluoride PVDF ; and the solvent, N-methylpyrrolidone NMP. Additionally, a polysaccharide polymer chitin crosslinked with maleic anhydride was prepared as an ion-permeable compound 4.
