Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a battery,
More particularly, it relates to the removal of hydrogen released from a battery. The present invention relates to batteries that are particularly useful for use in sealed partitions, such as in cameras and flashes.

2. Description of the Related Art A conventional alkaline battery generally has a cylindrical steel can having a positive electrode called a cathode, the positive electrode having manganese dioxide as an active material, and generally having a steel can. It is formed on the inner surface. Dry batteries also have a negative electrode called an anode, which has zinc powder and is generally located in the center of a steel can. A separator is provided between the positive electrode and the negative electrode, and the alkaline electrolyte is simultaneously in contact with the positive electrode, the negative electrode, and the separator. A conductive collector is inserted into the anode active material and seal assembly, the seal assembly having a seal and plugging the open end of the steel can to seal the active material from leaking.

[0003] Standard alkaline batteries are commercially available that provide an open circuit voltage of about 1.5V. When higher voltages are required, it is common practice to combine multiple cells to form a battery having that required voltage. At that time, a plurality of batteries are placed in a container and connected in series. In addition, external terminals are attached to the outside of the container,
Make an electrical connection with the battery in the container.

Generally, a small amount of hydrogen is generated in an alkaline battery due to corrosion of a zinc anode. Typically, some hydrogen accumulates in the battery seal, but some hydrogen leaks through the seal and out of the closed volume of the battery. In addition, evacuable seals are often used to release hydrogen out of the cell when excessive pressure builds up in the cell. Excessive hydrogen accumulation can lead to unacceptable conditions, especially in sealed containers. For example, if hydrogen accumulates in the sealed battery container of an electrical device, such as a flash, it can cause problems with the operation of the device. Also, for example, if hydrogen accumulates in a commercially available disposable camera in a sealed hermetic package, the silver on the photographic film will be reduced and the film will be covered, reducing the quality of the film.

[0005] To remove hydrogen, a hydrogen absorption / recombination catalyst has been used. For example, it is known that hydrogen absorbing materials, such as hydrogen getters and recombination catalysts, can be used to prevent the accumulation of hydrogen by being placed in a flash sealed battery container. However, only a limited number of electrically actuated devices are used with hydrogen scavengers. further,
The aging of the hydrogen scavenger impairs the effectiveness of the flash.

[0006] It is therefore desirable to reduce the build up of hydrogen in and around batteries.
Further, it is desirable to remove accumulated hydrogen gas from batteries used in sealed battery operated devices. It is also desirable to remove hydrogen released from flashes and batteries in cameras.

The present invention provides a means for removing hydrogen generated from a battery by supplying a hydrogen removing agent to the battery.

[0027]

FIG. 1 shows a cylindrical alkaline battery 10. The alkaline battery 10 has a cylindrical steel can 12 having a closed bottom end 14 and an open top end 16. The closed bottom end of the can 12 has a positive electrode cover made of plated steel with a central projection 18 at the center thereof, and the projection 18 serves as a positive terminal of the battery 10. On the other hand, the open end 16 of the can 12 has a cover and a seal assembly serving as a negative terminal of the battery 10. Except for the ends of the can 12, metallized plastic film labels 20 are formed on the outer surface of the steel can 12. The film label 20 is formed on the peripheral edge of the positive cover.

The cathode 22 is made of manganese dioxide, graphite,
5% potassium hydroxide solution, deionized water, Teflon ™ aqueous solution containing about 20% polytetrafluoroethylene,
And additives and are formed around the inner surface of the can 12. The separator 24 is preferably made of a nonwoven fabric that prevents the movement of solid particles in the battery, and is provided around the inner surface of the cathode 22. The anode 26 preferably comprises zinc powder, a gel and additives, and is provided with the electrolyte inside the separator 24 and is in contact with a current collector 28 having brass nails. Therefore, the cathode 22 is arranged as the positive electrode of the battery, and the anode 26 is arranged as the negative electrode of the battery.

The current collector 28 is in contact with the outer negative cover 30 which is the negative terminal of the battery 10. An annular plastic (nylon) seal 32 is provided within the open end 16 of the steel can 12 to prevent leakage of the active battery components contained within the steel can 12.

One example of the hydrogen removing agent is a composition comprising an organic polymer having a double bond as described in the above-mentioned US patent, and more specifically, a carbon-carbon double agent such as polybutadiene and polyisoprene. Examples include a combination of a hydrogen scavenger such as a hydrocarbon polymer having a bond or a derivative thereof such as 1,4-phenylbutadiene and a hydrogenation catalyst such as palladium or another Group VIII metal. These generally react with hydrogen in a conventionally known chemical reaction with hydrogen to form a solid or liquid product and capture the hydrogen. If necessary, a molded piece may be formed with an appropriate binder (such as a moldable resin). In the present invention. Of course, other known hydrogen scavengers can also be used in batteries according to the present invention.

Further, the hydrogen removing agent 40 may be disposed inside or outside the cover of the positive electrode. Further, the hydrogen scavenger 40 may be integrally formed within the label 20.

FIG. 5 shows a multi-cell battery 50 including a plurality of cells 10. Multi-cell battery 50
Consists of six batteries 10 connected in series, forming a 9V battery. The multi-cell battery 50 has a container 52 surrounding the six batteries 10, and a positive terminal 54 and a negative terminal 56 provided at the top end of the container 52. Multi-cell battery 50 preferably has a hydrogen scavenger 40 for removing hydrogen released from battery 10 provided on an inner surface, such as the inner wall of container 52. Although the hydrogen scavenger 40 is shown on the inner surface of the side wall of the container 52, it may be provided on the top or bottom wall, the outer surface of one or more batteries 10, or on the outer surface of the container 52.

FIG. 6 shows the performance of a battery having a hydrogen removing agent in the form of a hydrogen recombination catalyst attached to the inner surface of the outer negative cover 30 of FIG. 3 and the performance of a battery having no hydrogen removing agent 40. Shown in comparison. In particular, cylindrical AA size alkaline cells were tested at 50 ° C. and 71 ° C. for two weeks. The hydrogen volume was measured by placing the battery in the bag at the corresponding temperature for two weeks. Take an air-integrated sample and measure to obtain a total g weight, measure the total volume of air and multiply by the percentage of hydrogen to arrive at the hydrogen volume measurement. Two batteries with the hydrogen scavenger 40 attached to the bottom surface of the outer negative cover 30 were tested and the volume of hydrogen accumulated in each battery was measured. The hydrogen volume measurement of one cell tested at 50 ° C. is indicated by reference numeral 64 in FIG. 6, and the hydrogen volume measurement of another cell tested at 71 ° C. is shown in FIG.
66. In contrast, a conventional battery without hydrogen scavenger had a 6 in FIG.
In the tests at 0 and 71 ° C., 62 in FIG. 6 showed a high hydrogen volume measurement result. As can be seen from FIG. 6, the hydrogen removing agent 40 is different from a conventional battery not including the hydrogen removing agent 40.
The hydrogen accumulation volume in the battery was greatly reduced. Further, FIG.
The graph shows that as the temperature increases, the amount of accumulated hydrogen increases.

Thus, the hydrogen scavenger 40 is located in a battery or multi-cell battery outside of the closed volume containing the electrochemically active material to reduce the amount of hydrogen released from the battery into the atmosphere. Batteries are used in electrically operated devices that often use a sealed battery compartment, such as flashes and cameras. By providing the battery with a hydrogen scavenger, the amount of hydrogen present in the device can be reduced without having to incorporate it directly into the device.

Without departing from the technical idea of the present invention,
It will be understood by those skilled in the art that various changes and modifications can be made to the present invention. The scope of protection afforded should be determined by the appended claims and the breadth of interpretation by law.
