DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermal battery equipped with a heat generating agent, and provides a thermal battery that can simultaneously supply power to a plurality of loads with one battery.

As is well known, thermal batteries operate at high temperatures of several hundred degrees, making them suitable for drawing large amounts of current in a short period of time, and various improvements have been made to date. However, as electronic devices have become more sophisticated and diversified in recent years, there have been many cases in which this type of emergency power source is required to simultaneously supply power to several types of loads.

As a conventional idea for dividing the battery within the case, there is, for example, Japanese Utility Model Publication No. 49-96. This involves dividing the battery into four parts, inserting an insulator such as mica between each group, and connecting these four parts in series to obtain a high voltage. At the same time, when molding a large electrode plate, non-uniformity is likely to occur even within one electrode plate.
They are individually molded into four circles to form separate groups, and later connected to form one battery. However, with this method, it is difficult to supply power to loads of different sizes. Furthermore, it is not easy to evenly ignite exothermic agents such as thermite.

他の例は、特公昭37−18119号公報のように、
偶数に等分割した極板ブロツクに分け、各ブロツ

ドミウム電池を得ようとする工夫もある。この例

Other examples include Japanese Patent Publication No. 37-18119,
Another idea is to divide the electrode plate into an even number of equally divided blocks and divide each block into a positive electrode and a negative electrode in an attempt to obtain a large-capacity nickel-cadmium battery. In this example, each block is a positive or negative electrode block and is not a battery group.

3a, 3b, 3c, and 3d are sector-shaped batteries constructed from a stack of disk-shaped power generation elements divided into sectors, and the areas of their electrode plates are directly proportional to different required loads. For example, if a device requires four types of load currents 3A, 5A, 2A, and 6A at the same time, batteries 3a, 3b, 3c, and
The ratio of the electrode plate areas of d is divided into a ratio of 3:5:2:6. Of course, the number of batteries and the area ratio of the electrode plates can be changed arbitrarily depending on the number and size of loads.

Reference numeral 6 denotes a cylindrical through-hole which is common to the exothermic agent of each battery, and is provided in the center of the battery arranged in the battery case so that it is separated from each other by an insulating material and forms a columnar shape as a whole. In the battery, the ignition point of the exothermic agent is exposed at this through vent as an arcuate end face proportional to the area of the exothermic agent. This configuration is important for simultaneously igniting the exothermic agents that each battery has, such as metal iron powder and potassium chlorate, or metal zirconium and barium chromate, to obtain a uniform temperature rise rate. That is, since the length of the arc portion where the exothermic agent of each battery is exposed to the vent 6 is directly proportional to the area of each electrode plate, a uniform temperature rise rate can be obtained regardless of the size of the electrode plate.

(2) Uniform ignition is possible because the size of the ignition point necessary for igniting the exothermic agent can be set in proportion to the area of the exothermic agent. Since a thermal battery generates voltage only after it is activated by the heat of the exothermic agent, if there is a delay in heat generation, the voltage rise will be delayed, but there is no such inconvenience.

各電池を同時に着火することができる。
(3) Since each battery has a common vent and can be activated with only one ignition source,
Each battery can be ignited simultaneously.
