非水電解質二次電池用正極の製造方法

Japanese Patent JP4560079

B2

A nonaqueous electrolyte secondary battery includes: a positive electrode 4 including a positive electrode current collector and a positive electrode mixture layer containing a positive electrode active material and a binder, the positive electrode mixture layer being provided on the positive electrode current collector; a negative electrode 5; a porous insulating layer 6 interposed between the positive electrode 4 and the negative electrode 5; and a nonaqueous electrolyte. The positive electrode 4 has a tensile extension percentage of equal to or higher than 3.0%. The positive electrode current collector is made of aluminium containing iron. In this manner, the tensile extension percentage of the positive electrode is increased without a decrease in capacity of the nonaqueous electrolyte secondary battery. Accordingly, even when the nonaqueous electrolyte secondary battery is destroyed by crush, occurrence of short-circuit in the nonaqueous electrolyte secondary battery can be suppressed.
