Abstract:
A nonaqueous electrolyte secondary battery includes a power generating element including a positive electrode having a positive electrode active material layer and a negative electrode having a negative electrode active material layer. A main plane having the smaller area, between a main plane of the positive electrode active material layer and a main plane of the negative electrode active material layer, has an approximately rectangular shape with a short side having a length of 132 mm or more. The positive electrode active material layer and the negative electrode active material layer are provided such that the main plane of the positive electrode active material layer and the main plane of the negative electrode active material layer face each other with a separator interposed therebetween, and the positive electrode active material layer contains a binder in an amount of 2 mass % or more and 3.5 mass % or less.
