Abstract:
A secondary battery suppresses generation of wrinkle at the outer peripheral edge portion of a negative electrode plate due to expansion of a negative electrode active material layer with use. The secondary battery includes a positive electrode plate with a positive electrode active material layer disposed on a first current collector, and a negative electrode plate with a negative electrode active material layer having an area larger than an area of the positive electrode active material layer disposed on a second current collector. The negative electrode plate includes a facing portion facing the positive electrode active material layer and a non-facing portion. The negative electrode plate and a separator are bonded through a bonding layer. The bonding strength of a second bonding portion that bonds the non-facing portion to the separator is larger than the bonding strength of a first bonding portion that bonds the facing portion to the separator.

Claim (Index 1):
A secondary battery comprising a power generating element, wherein a positive electrode plate, in which a positive electrode active material layer is disposed on at least one surface of a first current collector, and a negative electrode plate, in which a negative electrode active material layer having an area larger than an area of the positive electrode active material layer is disposed on at least one surface of a second current collector, are stacked with a separator holding an electrolyte interposed therebetween in a state in which the positive electrode active material layer and the negative electrode active material layer face each other,\n the negative electrode plate comprises a facing portion facing the positive electrode active material layer with the separator interposed therebetween and a non-facing portion positioned at the outer periphery of the facing portion and not facing the positive electrode active material layer with the separator interposed therebetween, the negative electrode plate and the separator are bonded through a bonding layer, and in the bonding layer, bonding strength of a second bonding portion that bonds the non-facing portion to the separator is larger than bonding strength of a first bonding portion that bonds the facing portion to the separator.
