| titleOfInvention |
Secondary battery and manufacturing method of secondary battery |
| abstract |
The present invention provides a secondary battery and a method for producing the secondary battery which can suppress the occurrence of wrinkles caused by expansion and contraction of the negative electrode active material layer in the outer peripheral portion of the negative electrode. The negative electrode active material layer (34) has: an opposing portion (42) facing the positive electrode active material layer (64) with the electrolyte layer (50) interposed therebetween; and a non-opposing portion (44) located on the outer periphery of the opposing portion (42) And it does not oppose the positive electrode active material layer (64), and the expansion ratio of the non-opposing portion (44) is smaller than that of the opposing portion (42). |
