Title:
NONAQUEOUS ELECTROLYTE SOLUTION SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2003007304
Kind Code:
A
Abstract:

To provide a nonaqueous electrolyte solution secondary battery which is superior in weighing of a mixture powder with a carbonaceous material of a negative active material and a binder and has a robust negative electrode.

In a nonaqueous electrolyte solution secondary battery 1 in which a mixture powder with a carbonaceous material of a negative active material and a binder is weighed and press molded to manufacture a negative electrode, organic compound which has glass transition temperature of 7 to 40°C and does not include fluorine is used as the binder of the negative electrode. Preferably the organic compound of the binder, which does not include fluorine, is styrene-butadiene rubber, denatured polyacrylate, and so forth.
