Title:
電極保護膜形成剤
Document Type and Number:
Japanese Patent JP5827404
Kind Code:
B2
Abstract:
Described is an electrode or electrolyte solution for an electrochemical device that can be used in a wider temperature range with good long-term stability. An electrode protection film forming agent contains a compound having a urethane bond and a polymerizable unsaturated bond and preferably represented by general formula (1): A(-NHCO2—X)n. A is i) an n-valent C2-42 hydrocarbon group, ii) a trivalent residue obtained by removing three isocyanate groups from a trimer of a C2-42 diisocyanate (B), or iii) a divalent residue obtained by removing two isocyanate groups from a urethane prepolymer having isocyanate groups at both ends and being a reaction product of C2-42 diisocyanate (B) and C2-20 diol (N). X is a monovalent C3-42 organic group having a polymerizable unsaturated bond (b), n is an integer of 1 to 6, and when n is 2 or more, multiple X may be the same or different from each other.
