An effective method is to connect a fuse or the like. In other words, all of these methods involve providing a protective function element outside the battery to protect the battery.

Overcharging and overdischarging during battery charging are detected using a protective function element installed outside the battery, and the external circuit is cut off. However, the most dangerous situation with batteries is when the positive and negative electrodes Direct contact. When this contact occurs between the electrodes, a large current flows inside the battery, which generates C heat due to Joule heat, causing the internal temperature of the battery to rise.
Conventional technology cannot prevent this type of hazard or provide safety measures after it occurs.

ていないのが現状である。Figure 6 is a block diagram of a battery assembly in which multiple batteries are connected in series.If the battery is forcibly discharged with this connection, the polarity and e polarity will change in a battery with poor battery performance. A so-called polarity reversal occurs. In order to prevent this situation, it is known to connect a diode in parallel to each battery. Here, when battery ■ reverses polarity, current flows in the forward direction through the diode connected in parallel with battery ", so battery ■ will not reverse polarity deeper than the forward voltage drop of the diode. In other words, , most of the current does not flow through the battery ■, but through the diode.Although forced discharge does not significantly increase the temperature of the battery, this method prevents electrical shorts and overdischarge outside the battery. On the other hand, it is clear that '['] cannot be an effective means to prevent short circuits between electrodes inside the battery by simply protecting batteries with low battery performance. Currently, no effective countermeasures have been taken.

して一体化する。The battery uses lithium for the negative electrode, a carbon electrode for the positive electrode, and a mixed non-aqueous solution of thionyl chloride and lithium aluminum tetrachloride, which are active materials for the positive electrode, as the electrolyte. FIG. 1 shows a carbon electrode for reducing a positive electrode active material according to the present invention, and shows a structure in which a carbon electrode 1 is superimposed on a separator 2 that electrically insulates a carbon electrode 1 and a lithium electrode. The separator 2 is made of inorganic fibers that are chemically and mechanically stable against the mixed non-aqueous solution, and its dimensions are 43mm wide, 500mm long, and 0.2mm thick.
rtm. The carbon electrode is manufactured as follows. First, polytetrafluoroethylene dispersion is added to a mixture of carbon powder and an appropriate amount of water in an amount ranging from 3 to 504 of the total weight in terms of polytetrafluoroethylene, and the mixture is kneaded. This kneaded product is applied to a nickel or stainless wire mesh, dried, pressure molded, and then fired in air at a temperature in the range of 280 to 340"C to obtain a porous carbon electrode. Carbon electrode 1
The dimensions are width 40III, length 86, thickness 0.5
Five of these carbon electrodes 1 are stacked on top of the separator 2 at intervals of 51. As shown in the figure, the carbon electrode 1 has a protective function element 3 welded to a nickel or stainless wire mesh using a resistance welder. Carbon [Lay another separator on top of pole 1 and press-mold to integrate.

−塩化チオニール電池を示す。Through this pressure molding, the carbon electrode 1 becomes the upper and lower separators 2.
Since the carbon electrode 1 and the lower separator 2 are embedded in each other, the carbon electrode 1 and the lower separator 2 are completely integrated without creating a gap. As shown in FIG. 2, this is stacked on the lithium electrode 7,
The electrode group 5 is formed by spirally winding the lithium electrode 7 so that it is located on the inside at the beginning of the winding. From this electrode group 5, there are five protective function elements 3 which also serve as terminals for the carbon electrode 1, and a terminal 6 for purely extracting electricity for the lithium electrode 7. In this embodiment, a protective function element 3 which is disconnected when a current exceeding tOX flows is used. FIG. 3 shows an electrode group 5 stored in a storage can 12 and five protective function elements 3.
A terminal 6 for the lithium electrode 7 is insulated with ceramic 1 in the center of the battery lid 8, and a terminal 6 for the lithium electrode 7 is welded to the inner wall of the storage can 2, and the storage can 12 is sealed with the battery lid 8. - Indicates a thionyl chloride battery.

A terminal 4 from the input point of the five carbon electrodes 1 shown in FIG. 1 is connected to this. Therefore, when the spare terminal IO and the storage can 12 are connected outside the battery, one of the five carbon electrodes and the lithium electrode 7 are electrically short-circuited inside the battery. In the battery shown in FIG. 3, the battery cover 8 and storage can 12
The peripheral joints are continuously fused welded using a Rede welding machine. The output terminal 9 in the center of the battery cover 8 is shaped like a metallic tube. The battery is completed by injecting lysate and sealing the opening. However, when manufacturing a battery as a product, the spare terminal 1o is not necessary.
