Abstract
According to one embodiment, an electrode is provided. The electrode includes a current collector and an active material-containing layer formed on the current collector. The active material-containing layer contains a lithium nickel cobalt manganese composite oxide and a lithium cobalt composite oxide. Pore size distribution obtained by mercury intrusion porosimetry for the active material-containing layer has a first peak top indicating a highest intensity Iwithin a pore size range of from 0.1 μm to 1 μm and a second peak top indicating an intensity Iwhich is a second highest intensity after the highest intensity Iwithin the pore size range of from 0.1 μm to 1 μm. A pore size at the first peak top is smaller than a pore size at the second peak top.
