Abstract:
A binder for an electrode of a lithium secondary battery contains a water dispersion of a polyurethane. The polyurethane has been formed of (A) a polyisocyanate, (B) a compound having two or more active hydrogen groups, (C) a compound having one or more active hydrogen groups and a hydrophilic group, and (D) a chain extending agent. The (B) compound having two or more active hydrogen groups contains an olefinic polyol and/or a carbonate diol having a carbon number between carbonate bond chains of less than 6. The binder has high adhesiveness to a collector, does not cause release in press molding, has high flexibility, and is excellent in bindability and resistance to an electrolytic solution.

Claim (Index 11):
A binder for an electrode of a lithium secondary battery, comprising a water dispersion of a polyurethane formed of\n (A) a polyisocyanate that contains an alicyclic isocyanate and/or an aromatic isocyanate, (B) a compound having two or more active hydrogen groups comprising 40% by mass or more and 90% by mass or less with respect to the polyurethane of an olefinic polyol and, optionally, a polycarbonate diol having a carbon number between carbonate bond chains of less than 6, wherein the olefinic polyol is at least one selected from polybutadiene polyol, polyisoprene polyol, hydrogenated polybutadiene polyol, and hydrogenated polyisoprene polyol, (C) a compound having one or more active hydrogen groups and a hydrophilic group, and (D) a chain extending agent, wherein the polyurethane has a crosslinking density of 0.01 or more and 0.50 or less per 1,000 molecular weight of the polyurethane.
