Disclosed is a binder for electrode formation, which is obtained by dispersing a polyolefin resin containing 50 to 98% by mass of an unsaturated hydrocarbon having 3 to 6 carbon atoms and 0.5 to 20% by mass of an unsaturated carboxylic acid unit in an aqueous medium together with a basic compound. This binder for electrode formation is also characterized in that the content of a nonvolatile water-compatibilizing agent is 5 parts by mass or less per 100 parts by mass of the polyolefin resin.

Binder for electrode formation, slurry for electrode formation using the binder, electrode using the slurry, rechargeable battery using the electrode, and capacitor using the electrode

Using a gas barrier resin composition including 83 to 15% by mass of a compound (A) having two or more hydroxyl groups in a molecule thereof and 17 to 85% by mass of a compound (B) in which at least one carboxyl group is bound to each of three or more consecutive carbon atoms in a molecule thereof, wherein the compound (B) is any one of a compound in which no anhydrous structure is made among the carboxyl groups and a compound in which at least one anhydrous structure is made among the carboxyl groups, or using a gas barrier coating agent including the compound (A), the compound (B) and a solvent, the present invention provides a gas barrier molded material, which has high gas barrier property in that it has less reduction of gas barrier property even in a high humidity atmosphere, has excellent transparency, does not generate poisonous gas when it is subjected to an incineration treatment, is friendly to the natural environment because of the non-use of organic solvents, and has good productivity.
