<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery and a negative electrode which are prevented from being cracked while improving the productivity of the electrodes, particularly, the negative electrode. <P>SOLUTION: Disclosed is the nonaqueous electrolyte secondary battery equipped with a positive electrode, the negative electrode, and a nonaqueous electrolyte. The negative electrode contains a negative electrode mixture including a binder, the binder contains polyvinylidene fluoride and acrylonitrile, and the mass ratio of the polyvinylidene fluoride to acrylonitrile is 99.9:0.1 to 95.1:4.9. <P>COPYRIGHT: (C)2009,JPO&INPIT |
