Abstract:
A lithium-ion secondary battery that includes an electricity-generating unit that includes: a positive electrode having a positive electrode collector, and a positive electrode mixture layer formed on a surface of the positive electrode collector; a negative electrode having a negative electrode collector, and a negative electrode mixture layer formed on a surface of the negative electrode collector; and a separator disposed between the positive electrode and the negative electrode. At least one of the positive electrode mixture layer and the negative electrode mixture layer has a high-density portion of high mixture density, and a low-density portion having a lower mixture density than the high-density portion and being in contact with the high-density portion. The low-density portion has a smaller area than the high-density portion when viewed in plan.

Claim (Index 2):
The lithium-ion secondary battery according to  claim 1 , further comprising a density gradient region at a boundary between the high-density portion and the low-density portion, and in at least a part of regions in the vicinity of the boundary, the density gradient region being a region where the density shows gradual changes from place to place.
