密度化が可能であり、且つ放電時における電池電圧の低
下が少ないため、電池を用いたテープレコーダ等の各種
電気機器を長時間使用することが可能である。2. Description of the Related Art In recent years, a metal-hydrogen alkaline storage battery has attracted attention as a new type of alkaline storage battery that replaces a nickel-cadmium battery. This metal-hydrogen alkaline storage battery can have a high energy density and has a small decrease in battery voltage at the time of discharging, so that various electric devices such as a tape recorder using a battery can be used for a long time.

金属−水素アルカリ蓄電池を用いた場合には、上記の如

になって急激に電池電圧が低下するため、電池の電圧を
測定して残存容量を表示するのが困難となる。この結
果、電気機器の残り使用時間を使用者に知らしめること
ができる、利便性が低下するという課題を有していた。Problems to be Solved by the Invention By the way, many of the above-mentioned electric devices are provided with a function of measuring the voltage of a battery and displaying a remaining capacity to improve the convenience of a user. However,
When a metal-hydrogen alkaline storage battery is used, the battery voltage decreases during discharge as described above, and the battery voltage sharply decreases at the end of discharge, so the battery voltage is measured and the remaining capacity is displayed. It will be difficult to do. As a result, there is a problem that the user can be informed of the remaining use time of the electric device, and the convenience is reduced.
本発明はかかる現状に鑑みてなされたものであり、電

ル蓄電池を提供することを目的とする。The present invention has been made in view of the above situation, and has an object to provide a metal-hydrogen alkaline storage battery that can notify a user of a remaining use time of an electric device using a battery and improve convenience. And
課題を解決するための手段 本発明は上記目的を達成するために、可逆的に水素を
吸蔵，放出する水素吸蔵合金を含む負極と、この負極に
対向配置された正極とを有する金属−水素アルカリ蓄電
池において、前記負極は、平衡圧が高い合金から成る高
平衡圧部と、平衡圧が高い合金よりも平衡圧が低い合金
から成る低平衡圧部とが、正極と対向する平面内の互い
に異なる領域に配されて構成されていることを特徴とす
る。Means for Solving the Problems In order to achieve the above object, the present invention provides a metal-hydrogen alkali having a negative electrode including a hydrogen storage alloy that reversibly stores and releases hydrogen, and a positive electrode disposed opposite to the negative electrode. In the storage battery, the negative electrode has a high equilibrium pressure portion made of an alloy having a high equilibrium pressure and a low equilibrium pressure portion made of an alloy having a low equilibrium pressure than the alloy having a high equilibrium pressure, which are different from each other in a plane facing the positive electrode. It is characterized by being arranged in a region.
作用 上記構成の金属−水素アルカリ蓄電池を放電する場合
には、放電電圧の高い高平衡圧部が放電された後に放電
電圧の低い低平衡圧部が放電される。したがって、放電
当初は放電電圧が高い状態にあるが、放電終期になって
くると放電電圧が低くなるので、電池電圧を測定して残
存容量を表示することが可能となる。When discharging the metal-hydrogen alkaline storage battery having the above-described configuration, the low-equilibrium pressure portion having a low discharge voltage is discharged after the high-equilibrium pressure portion having a high discharge voltage is discharged. Therefore, although the discharge voltage is high at the beginning of discharge, the discharge voltage decreases at the end of discharge, so that it is possible to display the remaining capacity by measuring the battery voltage.
尚、高平衡圧を有する水素吸蔵合金と低平衡圧を有す
る水素吸蔵合金とを混合して電極を作製したのでは上記
の効果を得ることはできない。これは、蓄電池において
は、一般に正極容量が負極容量よりも小さな、所謂正極
支配の電池となっているため、上記の如く両者を混合し
たような構成では水素吸蔵合金が全て使用されず（即
ち、放電開始時期が遅い低平衡圧の水素吸蔵合金が余り
用いられない）、この結果電池電圧が低下しない。これ
に対して、前記本発明の構成であれば、高平衡圧部及び
低平衡圧部にそれぞれ対向している正極のみが充放電反
応に関与するので、低平衡圧の水素吸蔵合金も十分に反
応に関与することになる。したがって、放電終期になる
と放電電圧が低くなるという理由に起因する。It should be noted that the above effects cannot be obtained if an electrode is manufactured by mixing a hydrogen storage alloy having a high equilibrium pressure and a hydrogen storage alloy having a low equilibrium pressure. This is because, in a storage battery, the positive electrode capacity is generally smaller than the negative electrode capacity, that is, the battery is dominated by the positive electrode. Therefore, in the configuration in which the two are mixed as described above, all the hydrogen storage alloy is not used (that is, A low equilibrium pressure hydrogen storage alloy whose discharge start time is late is rarely used, and as a result, the battery voltage does not decrease. On the other hand, according to the configuration of the present invention, only the positive electrode facing the high equilibrium pressure portion and the low equilibrium pressure portion are involved in the charge / discharge reaction. Will be involved in the reaction. Therefore, the reason is that the discharge voltage decreases at the end of discharge.
