のニッケル亜鉛蓄電池に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nickel zinc storage battery, and more particularly, to a nickel zinc storage battery having a relatively large capacity which can be forcibly cooled for use in vehicles such as electric vehicles and solar cars.

その中で亜鉛を負極活物質とした電池は単位重量当りの
エネルギー密度が大きくしかも安価であるといった利点
を有する。2. Description of the Related Art As is well known, there is a great demand for higher energy density and higher performance of batteries, from electric vehicles to portable devices.
Among them, a battery using zinc as a negative electrode active material has an advantage that the energy density per unit weight is large and inexpensive.

こす。On the other hand, when this zinc electrode is operated as a negative electrode of a storage battery, the zinc active material dissolves and precipitates in a discharging process or a charging process, causing problems such as so-called shape change and dendrite short. In the charging process, zinc metal crystals precipitated from zincate ions tend to become dendrite crystals due to the catalytic action of hydrogen, especially when accompanied by generation of hydrogen gas, causing a short circuit in the battery.
【０００４】そのため従来より充電末期になっても負極

から酸素ガスを優先させて発生するようにして、充電過
程全てにおいて負極からは水の電気化学的分解による水
素ガス発生を起こらないようにし、デンドライト状の析
出が発生しないように工夫されている。Therefore, conventionally, the capacity of the negative electrode is increased from the capacity of the positive electrode so that hydrogen is not generated from the negative electrode even at the end of charging, and oxygen gas is generated from the positive electrode with priority even in the state of final charging after charging the battery. In this way, hydrogen gas is not generated from the negative electrode due to the electrochemical decomposition of water during the entire charging process, so that dendrite-like deposition is not generated.

ッケル亜鉛電池がある。Further, when the above-mentioned battery is charged and discharged and cycled as a secondary battery, if oxygen generated from the positive electrode leaks out of the battery system, the capacity balance between the positive electrode and the negative electrode is lost, and eventually the negative electrode becomes negative. , And the battery life is shortened by zinc dendrite precipitation. Therefore, in order to maintain the capacity balance between the positive electrode and the negative electrode during cycle use, there is a sealed nickel-zinc battery in which the amount of electrolyte in the battery is limited and oxygen gas generated at the end of charging is absorbed and recycled by the negative electrode.
【０００６】また、前述したシェイプチェンジは、電池

寿命が短くなるという特徴がある。The above-mentioned shape change is closely related to the temperature of the battery, and the higher the temperature of the battery, the shorter the life of the battery.

の低下することが問題となっていた。When a nickel-zinc storage battery is used in an electric vehicle or a solar car, the heat radiation of the battery mounting location is poor, and the temperature of the battery tends to rise, especially the temperature rises above room temperature. As a result, there is a problem that the battery life is shortened.
【０００８】また、放電後において電池の温度が上昇し
