NEGATIVE ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, AND PROCESS FOR PRODUCTION THEREOF

It is equipped with a negative-electrode current collector, and a negative-electrode mixture-material layer comprising a negative-electrode mixture material that includes a negative-electrode active material containing silicon (Si) and a binding agent at least, the negative-electrode mixture-material layer being formed on a surface of the negative-electrode current collector; and the binding agent includes a polyimide-silica hybrid resin being made by subjecting a silane-modified polyamic acid to sol-gel curing and dehydration ring-closing, the silane-modified polyamic acid being expressed by the following formula (wherein: "R" specifies an aromatic tetracarboxylic dianhydride residue including 3,3',4,4'-biphenyltetracarboxylic dianhydride residue in an amount of 90% by mole or more; "R" specifies an aromatic diamine residue including a 4,4'-diaminodiphenyl ether residue in an amount of 90% by mole or more; "R" specifies an alkyl group whose number of carbon atoms is from 1 to 8; "R" specifies an alkyl group or an alkoxy group whose number of carbon atoms is from 1 to 8 independently of one another; "q" is from 1 to 5,000; "r" is from 1 to 1,000; and "m" is from 1 to 100).
