A battery includes an air cathode, an anode, an aqueous electrolyte, and a housing, wherein, the housing includes one or more air access ports defining a total vent area, the battery exhibit a current density, a ratio of current density to total vent area is greater than about 100 mA/mm.sup.2, and the aqueous electrolyte comprises an amphoteric fluorosurfactant.

Provided is a laminate battery in which a short circuit between a negative electrode active material and a positive electrode due to expansion of the negative electrode active material during discharging is prevented.

A laminate battery includes a battery case that serves as an outer case. The laminate battery includes an inner case within a battery case 11, and the inner case is formed of a positive electrode storage case and a separator. An inside of the inner case serves as a positive electrode storage portion that stores a positive electrode. An outside of the inner case serves as a negative electrode storage portion that stores a negative electrode. The negative electrode uses a particulate negative electrode active material (e.g., zinc or zinc oxide).

In a battery casing a metal negative electrode that contains metal serving as a negative electrode active material and an air electrode are arranged so as to face each other in a state where at least a part of the metal negative electrode and the air electrode is immersed in an electrolytic solution inside a casing. The metal negative electrode is housed in a negative electrode housing in the casing. A separator separating the metal negative electrode and the air electrode is arranged at a side surface of the negative electrode housing. An opening through which inside of the negative electrode housing and outside of the negative electrode housing communicate with each other is provided on an upper surface of the negative electrode housing.

Provided are a laminated battery capable of suppressing a level drop of an electrolyte caused by expansion of a negative electrode active material during discharge, and a manufacturing method for the laminated battery.

An enclosure member of the laminated battery is constituted by affixing a first resin film and a second resin film to each other, and a separator is arranged inside the enclosure member between a positive electrode (for example, a first electrode) and a negative electrode (for example, a second electrode). A peripheral edge portion of the separator is fixed to a peripheral edge portion of the enclosure member (the first resin film or the second resin film).
