NEGATIVE ELECTRODE FOR SECONDARY BATTERY AND SECONDARY BATTERY EQUIPPED WITH SAME, AND RESIN PRECURSOR FOR BINDER, RESIN PRECURSOR SOLUTION AND BINDER COMPOSITION FOR USE IN PRODUCTION OF SECONDARY BATTERY

WIPO Patent Application WO/2011/071106

A1

Disclosed are: a negative electrode and the like which enable the production of a secondary battery having a good balance among properties including discharge capacity and cycle properties; and a resin precursor for a binder and the like which can be used for the production of the secondary battery and the like. Specifically disclosed are: a negative electrode for a secondary battery, in which a negative electrode active material is integrated with a binder that comprises a polyimide resin having a repeating unit represented by general formula (1); and a resin precursor for a binder for use in the production of a secondary battery, which is characterized by containing 50 mol% or more of a precursor of the polyimide resin. [In general formula (1), Ar1 represents a bivalent aromatic diamine residue having at least two ether bonds; and Ar2 represents a tetravalent acid dianhydride residue represented by formula (2) or (3).] [In formula (3), Y represents a direct bond or -CO-.]
