った。The Nofulh storage battery is a Ni-7n battery that uses, for example, a nickel hydroxide horizontal plate as a positive electrode, a zinc electrode as a negative electrode, and uses a caustic potassium aqueous solution or the like as an electrolyte. In addition, alkaline storage batteries are known as batteries that exhibit excellent characteristics at room temperature or at low temperatures below failure, contrary to lead storage batteries. However, at high temperatures, the charging efficiency of the battery, especially the charging efficiency of the positive electrode plate, decreases significantly, and the deterioration of the electrode plate becomes more significant.
When used at 81 degrees Celsius, the disadvantage is that the capacity decreases significantly and the life span is shortened. Therefore, conventionally the number II!
,! 1. There are almost no 1-type batteries, such as lead-acid batteries for automobiles, which are a collection of 1. However, it was a battery with a low energy density, in which the ratio of the electrode plates to the internal volume of the battery case was extremely small.

う問題が生じる。However, in recent years, there has been a growing demand for alkaline storage batteries that can charge and discharge at high rates due to the demand for high energy densities. Then, a problem arises in that battery temperature increases due to heat generated by the battery during charging and discharging, resulting in a decrease in performance as described above.

The battery is completed by inserting these electrode plates into each sliding part, attaching a lid to the top of the plate, electrically connecting them in series or parallel, and completing a 3-cell monoblock type battery. (3) is a metal plate embedded in the horizontally open partition wall (1') between adjacent unit cells, a part of which protrudes outside the m-cell. As a metal plate,
Metals with high thermal conductivity such as silver and aluminum are suitable for the body. Further, the direction in which the metal plate is made to protrude outside the battery case is not limited to both sides as shown in FIG. 1, but may be made to protrude from the top and bottom depending on the shape and size of the battery.

Further, it is preferable that the area of the metal plate and the heat sink (4) be as large as possible. In this example, the method of attaching the heat sink (4) to the metal plate (3) after forming the battery case was shown in C. However, as shown in Fig. 2, the metal plate (3) and the heat sink (4) were It may be kept as a single unit.
