Summary:In general, according to one embodiment, a battery including a positive electrode, a negative electrode, and a water-containing electrolyte is provided. A nitrogen-containing compound is present on at least a part of a surface of a negative electrode active material-containing layer. A pore volume of a positive electrode active material-containing layer according to a mercury intrusion method is represented by Vc (mL/g). A pore volume of the negative electrode active material-containing layer according to a mercury intrusion method is represented by Va (mL/g). The pore volume Va is 0.14 mL/g or less. The battery satisfies following expression (1):Vc>Va.(1)
