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 6):
A method for manufacturing a lithium-ion secondary battery, the method comprising:\n producing a positive electrode that includes a positive electrode collector, and a positive electrode mixture layer formed on a surface of the positive electrode collector; producing a negative electrode that includes a negative electrode collector, and a negative electrode mixture layer formed on a surface of the negative electrode collector; and disposing the positive electrode, a separator, and the negative electrode so as to interpose the separator between the positive electrode and the negative electrode, at least one of the positive electrode mixture layer and the negative electrode mixture layer having 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 having a smaller area than an area of the high-density portion when viewed in plan.
