摘要： According to one embodiment, an electrode includes a current collector, an active material-containing layer, a first peak, a second peak and a pore volume. The active material-containing layer contains an active material having a lithium absorption potential of 0.4 V (vs. Li/Li+) or more. The first peak has a mode diameter of 0.01 to 0.1 μm in a diameter distribution of pores detected by mercury porosimetry. The second peak has a mode diameter of 0.2 μm (exclusive) to 1 μm (inclusive) in the diameter distribution of pores. The pore volume detected by the mercury porosimetry is within a range of 0.1 to 0.3 mL per gram of a weight of the electrode excluding a weight of the current collector.

摘要： According to one embodiment, a battery electrode includes an active material layer and a current collector is provided. The active material layer contains particles of a monoclinic β-type titanium complex oxide and particles of a lithium titanate having a spinel structure. When a particle size frequency distribution of particles contained in the active material layer is measured by the laser diffraction and scattering method, a first peak P1 appears in a range of 0.3 μm to 3 μm and a second peak P2 appears in a range of 5 μm to 20 μm in the frequency distribution diagram. The ratio FP1/FP2 of the frequency FP1 of the first peak P1 to the frequency FP2 of the second peak P2 is 0.4 to 2.3.
