Embodiment Construction

[0022] Reference attached figure 1 , the battery 10 includes a casing 12 . Housing 12 includes an upper part 12a supporting the anode contacts and a lower part 12a supporting the cathode contacts. A first cylindrical part 12c is disposed between the upper and lower parts 12a, 12b, which first cylindrical part 12c forms together with the upper and lower parts the housing 12 or "battery box" of the battery 10 . The cylindrical member 12c has at least one aperture, here shown as a plurality of evenly spaced apertures, indicated generally at 13, arranged in a series of columns along the length of the cylindrical member 12c. In a typical configuration, each hole is 0.5-1.0 mm in diameter, but other diameters may be used and the holes need not be circular. In the exemplary embodiment, an "AA" cartridge is provided with 48 wells arranged in columns of 6 wells for a total of 8 columns, although a wide range of other sizes, numbers and configurations of wells may be used. Cylindrica...

Abstract

A battery includes a battery can housing an cell that supplies electrical energy at terminals of the cell by an electro-chemical reaction with oxygen, the can including, a first member having at least one hole that is exposed to air; and a second member. The battery also includes a mechanism coupled to one of the first and second members to move the one of the first and second members such that when current is drawn from the battery, the opening in the member allows air to pass into the battery, and to move the one of the first and second members such that when current is not drawn from the battery, the opening in the member is not in registration to inhibit air to pass into the battery. The battery also includes a circuit to control the mechanism. In one embodiment the circuit monitors levels of O2 in a air plenum that surrounds the cell. The circuit to monitor levels of O2 in the air plenum includes a florescent detector / sensor that senses and responds to changes in O2 in the plenum by using the 'quenching effect' 'of oxygen on a fluorescent material.

Description

technical field [0001] The present invention relates to a valve for fuel-air and metal-air batteries. Background technique [0002] Batteries are commonly used as a source of electrical energy. A battery contains a negative electrode (anode) and a positive electrode (cathode). The anode has active material that can be oxidized; the cathode has or consumes active material that can be reduced. The anode active material is capable of reducing the cathode active material. In order to prevent direct reaction of anode material and cathode material, anode and cathode are separated from each other by a separator. The electrolyte in contact with the anode and cathode contains ions that flow through the separator between the electrodes to maintain charge balance throughout the battery during discharge. [0003] In a metal-air electrochemical cell, oxygen is reduced at the cathode and metals such as zinc are oxidized at the anode. Oxygen is transported from the atmosphere outside ...
