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.
Information provided by Kleerdex Company. On the other hand, there are polymers having an average molecular weight of 50, or more such as the PVDF, PTFE, and 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.
These materials may be available by special order, in distribution inventory, or reinstated as an active product. 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.
Current collector for secondary battery, positive electrode for secondary battery, negative electrode for secondary battery, secondary battery, and manufacturing method of them. 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. Other examples include crosslinked polymers of a polysaccharide polymer such as chitosan or chitin crosslinked with a crosslinking agent, and the like.

A lithium-ion secondary battery was then prepared similarly, and the retention rate from initial capacity and the internal resistance thereof were determined under the conditions similar to those in Example 1, and the results are summarized in Tables 1 and 2.
However, the methods described in respective literatures were not sufficiently effective in repair the nonconformity. After intensive studies to achieve the object, the inventors have found that it was possible to solve the problems above by preparing a lithium-ion secondary battery in the structure in which an ion-permeable compound is in charge of lithium-ion conductivity and electron-conductive carbon fine particles of electron conductivity in particular in its cathode structure, and completed the present invention.
The molecular weight thereof was 30, as determined by GPC. Japanese Unexamined Patent Publication No. A method of producing a secondary battery, comprising: This application claims priority to Japanese Patent Application No. Please click here if you are a supplier and would like information on how to add your listing to this material. 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.
M Year of fee payment: In the present specification, aluminum means aluminum or an aluminum alloy, and copper means pure copper or a copper alloy. Electrode material, electrode material manufacturing method, electrode, and secondary battery. 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.
The molecular weight thereof was 35, as determined by GPC. Polyacrylamide cross-linked with a polysaccharide resin as electrophoretic gel medium. The current collector according to the present invention may have two films, upper and lower layers, on the aluminum foil.
Accordingly, desirable is a polymer having an average molecular weight of 50, or less, higher in adhesiveness to the metal foil, and particularly higher in the resistance to organic solvent.
US USB2 en Any one of known materials may be used as the anodic electroactive material for anode. 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.
The carbon fine particles used were gas-phase carbon fiber registered trade name: Polyamide, polyamide-imide and the like, which are known as the compounds resistant to organic solvent, are generally, very expensive and not practical. Data sheets from materials that are no longer available remain in MatWeb to assist users in finding replacement materials.
A secondary-battery cathode comprising: Battery active material powder mixture, electrode composition for batteries, secondary cell electrode, secondary cell, carbonaceous material powder mixture for electrical double-layer capacitors, polarizable electrode composition, polarizable electrode, and electrical double-layer capacitor.

Click here to view all the property values for this datasheet as they were originally d02002 into MatWeb. 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 jid or during the prosecution of the application, d002 examples are to be construed as non-exclusive.
The copper foil is also similar, and a rolled copper foil or an electrolytic copper foil is used favorably. A lithium-ion secondary battery was then prepared by connecting a separator and an anode current collector formed on a copper foil and impregnating the composite with an organic electrolyte solution in the step, in a similar manner to Example 1. The molecular weight thereof was 31, as determined by GPC. These properties can be determined by using a swelling test in solvent, a peeling test by using a cloth previously immersed in a solvent abrasion testand a tape-peeling test JIS D
