titleOfInvention |
Secondary battery and method for manufacturing secondary battery |
abstract |
A secondary battery includes a power generation element that includes a positive electrode having a collector on which a positive electrode active material layer is disposed, an electrolyte layer for retaining an electrolyte, and a negative electrode having a collector on which a negative electrode active material layer is disposed. The negative electrode active material layer has an area greater than that of the positive electrode active material layer. The negative electrode active material layer has a facing portion that faces a positive electrode active material layer with an electrolyte layer interposed by therebetween, and a non-facing portion that is positioned on an outer periphery of the facing portion and does not face the positive electrode active material layer. The non-facing portion has a stretching rate that is less than a stretching rate of the facing portion. |
