After weighing at 2:06 p.m., it was melted and cast in a high-frequency induction furnace, and M m N i L tc OA I o, IM
An alloy having a composition of no, a is obtained. This alloy was mechanically pulverized to a powder with an IV average size of approximately 80 μm, and then mixed with polyethylene oxide (1.0% heavy acid per 1M alloy type) and water as a dispersion medium to form a slurry. did.

After charging with a current of 100 mA at room temperature, activation treatment was performed by discharging with a current of 200 mA at each ambient temperature.

In the low-temperature, high-rate discharge tt of C (1000 mA) discharge, the discharge voltage of the batteries A-E, which had a charge amount of 0 to 30% during the activation treatment, decreased rapidly immediately after the start of discharge. In addition, for batteries F and K whose discharge temperature during activation treatment is 20°C,
Even though the amount of charge during the activation process is 50% or more, the charging voltage is relatively low at 111-J[JJ, and a discharge field of 1.min. (I couldn't get it.

It is clear from FIG. 2 that good results can be obtained under these activation treatment conditions.

It is a drawing showing the particle size distribution of the hydrogen storage alloy of the electrode.
Figure 4 shows a hole made in the bottom of the battery outer can of batteries F and I, a pressure sensor attached, and Ic (1000 mA).
3 is a diagram showing the results of measuring the internal pressure of a battery when high-rate charging is performed with a current of .

収性能が向１−シていると理解できる。As is clear from FIG. 3, the particle size of the negative electrode alloy of battery (1), which was discharged at 60°C, was smaller than that of battery F, which was discharged at 20°C. In other words, it can be seen that the reaction area is increased. Furthermore, from FIG. 4, it can be seen that the increase in internal pressure of the battery 1 is suppressed to a lower level than that of the battery F, and it can be understood that the battery 1 has a better oxygen gas absorption performance at the negative electrode.

て、充電効率がが向上したためと考えられる。As described above, the characteristics of a battery that is activated by charging to 50% or more of the chargeable capacity of the positive electrode and discharging in an atmosphere at a temperature of 30 to 80°C are improved due to this article f'. When activated in step 1, the surface of the hydrogen storage alloy used for the electrode 1]
This is thought to be because the oxide film of the alloy is easily broken, and the active cross section inside the alloy is exposed to the surface, which increases the reaction surface area and improves charging efficiency.
また、活性化処理時の放電雰囲気温度については、水素
吸蔵合金の脱水素反応（放電反応）が吸熱反応であるた
め、雰囲気温度が高くなるほど反応が進行し易くなる。Regarding the discharge atmosphere temperature during the activation treatment, since the dehydrogenation reaction (discharge reaction) of the hydrogen storage alloy is an endothermic reaction, the reaction progresses more easily as the atmosphere temperature becomes higher.
これによって、放電深度が深くなることも、工１極を活
性化する原因であると考えられる。This deepening of the depth of discharge is also thought to be a cause of activating the single pole.

しい。However, since battery configuration (2) discharging at extremely high temperatures risks deterioration of the separator, sealing, etc., the discharge atmosphere temperature during activation treatment is preferably 80° C. or lower.
