Abstract:
A lithium secondary battery of the present invention has a positive electrode is provided with a positive electrode mix layer that includes a positive electrode active material and a conductive material. The positive electrode mix layer has two peaks, large and small, of differential pore volume over a pore size ranging from 0.01 μm to 10 μm in a pore distribution curve measured by a mercury porosimeter. A pore size of the smaller peak B of the differential pore volume is smaller than a pore size of the larger peak A of the differential pore volume.

Claim (Index 8):
A method for producing a lithium secondary battery that is provided with a positive electrode that has a positive electrode collector and a positive electrode mix layer that includes, on a surface of the collector, a positive electrode active material and a conductive material,\n the method comprising the steps of: forming the positive electrode mix layer on a surface of the positive electrode collector; measuring a pore distribution of the positive electrode mix layer in use of a mercury porosimeter, and selecting a positive electrode such that the pore distribution curve obtained on the basis of the measurement satisfy the conditions below: there are two peaks, large and small, of differential pore volume in a pore size ranging from 0.01 \u03bcm to 10 \u03bcm; and from among the large and small peaks, a pore size in a smaller peak B of the differential pore volume is smaller than a pore size in a larger peak A of the differential pore volume; the method further including constructing a lithium secondary battery by using the selected positive electrode.
