ルカリ蓄電池に関する。TECHNICAL FIELD The present invention relates to a sealed alkaline storage battery used as a negative electrode in a hydrogen storage alloy that reversibly stores and releases hydrogen used in a negative electrode active material of a battery.

圧の上昇及び高率放電に大きく関与する。2. Description of the Related Art As a sealed alkaline storage battery, a nickel-cadmium battery has been widely put into practical use now for portable devices, and its capacity has been further increased. Recently, nickel-hydrogen batteries using a hydrogen storage alloy for the negative electrode have been tried. Also in this battery, the amount of the electrolyte has a great influence on the life of the battery, the increase in the internal pressure of the battery during charging, and the high rate discharge.
発明が解決しようとする問題点 ニッケル−水素蓄電池の高性能化においても電解液量が
重要な要因となるので、この電解液量の最適条件を求め
る必要がある。Problems to be Solved by the Invention Since the amount of the electrolytic solution is an important factor in improving the performance of the nickel-hydrogen storage battery, it is necessary to find the optimum condition of the amount of the electrolytic solution.
ニッケル−カドミウム蓄電池の反応は次式に示すように
進行する。The reaction of the nickel-cadmium storage battery proceeds as shown in the following equation.
この反応式においては活物質が化学変化する過程で必ず
カドミウム１分子に対して２分子の水が関与するため、
充・放電後には電解液中の水が増減することになる。し
たがって、電池反応系において電解液量を２分子の水だ
けは余分に入れ、調整をする必要がある。 In this reaction formula, two molecules of water are always involved for one molecule of cadmium in the process of chemically changing the active material.
After charging / discharging, the amount of water in the electrolytic solution will increase or decrease. Therefore, in the battery reaction system, it is necessary to adjust the amount of the electrolytic solution by adding only two molecules of water.
一方、ニッケル−水素蓄電池の全反応は下記に示すよう
に、この水の関与が直接的になく、イオンを導通するた
めの電解質があればよい。換言すれば、電池内部抵抗を
下げるに必要な最低の電解液量でよい事になる。On the other hand, the whole reaction of the nickel-hydrogen storage battery is not directly involved in the water and needs only an electrolyte for conducting ions, as shown below. In other words, the minimum amount of electrolyte required to reduce the internal resistance of the battery is sufficient.
ここで、MHは金属水素化物、Ｍは水素吸蔵合金である。 Here, MH is a metal hydride and M is a hydrogen storage alloy.

金中の水素と素早く反応して水に変化せず、電池内に酸
素ガスが充満し、安全弁の作動圧力以上に上昇すると、
その圧力によって電池内から電解液が漏出する現象が見
られる。Also in this nickel-hydrogen storage battery, when the amount of the electrolytic solution is reduced as in the case of the nickel-cadmium storage battery, the discharge voltage and cycle life of the nickel positive electrode are reduced. Oxygen is less likely to be efficiently ionized in the negative electrode due to excess electrolyte near the negative electrode, and it does not quickly react with hydrogen in the alloy on the surface of the negative electrode to change to water, filling the battery with oxygen gas. , When the pressure rises above the operating pressure of the safety valve,
There is a phenomenon in which the electrolyte leaks from the battery due to the pressure.
そこで、本発明は電池内に含有する電解液量を正極実質
容量に対して適正化し、高容量で長寿命のニッケル−水
素蓄電池を得ることを目的とする。Therefore, an object of the present invention is to obtain a nickel-hydrogen storage battery having a high capacity and a long life by optimizing the amount of electrolyte contained in the battery with respect to the substantial capacity of the positive electrode.
問題点を解決するための手段 水素吸蔵合金を負極とするニッケル−水素蓄電池におい

る。Means for solving the problem In a nickel-hydrogen storage battery using a hydrogen storage alloy as the negative electrode, the amount of electrolyte containing lithium hydroxide per unit real capacity of the positive electrode is regulated within the range of 1.8 to 2.6 cc / Ah. Is.

上昇することはなく、サイクル寿命が長く、しかも、高
い利用率から高容量となる作用を有する。Action As can be seen from the battery reaction, the nickel-hydrogen storage battery does not involve water, so the amount of electrolyte does not increase or decrease during charging and discharging. In the present invention, since the amount of the electrolytic solution containing lithium hydroxide that does not increase the battery internal resistance is maintained, the oxygen generated from the positive electrode is efficiently absorbed, the battery internal pressure does not rise, and the cycle life is long. Moreover, it has the effect of increasing the capacity from the high utilization rate.

要となる。As shown in the figure, if the amount of electrolyte containing lithium hydroxide is increased, the internal resistance of the battery is naturally lowered. The amount of electrolyte containing lithium hydroxide drops sharply up to 1.8 cc / Ah, but if it exceeds that amount, the resistance does not drop significantly and the value is almost constant 8-10.

電池内抵抗は大きく上昇し実用にはならない。However, when the amount of electrolytic solution is 1.8 cc / Ah or less, in a battery with a regulated positive electrode capacity, there is not enough electrolytic solution to maintain the positive electrode characteristic, and the polarization of the positive electrode becomes large, deteriorating the battery characteristic. When the charge / discharge cycle is further repeated, the electrolytic solution is naturally absorbed on the positive electrode side, and the battery characteristics deteriorate as the internal resistance of the battery increases. Thus, it can be seen that the amount of electrolytic solution containing lithium hydroxide is largely regulated in the battery with regulated positive electrode capacity. Especially in a non-sintered type such as a foamed nickel positive electrode that easily absorbs an electrolytic solution, it is important to optimize the amount of the electrolytic solution. The amount of the electrolyte solution containing lithium hydroxide is not regulated by the negative electrode but regulated by the positive electrode. The use of a 30 wt% KOH aqueous solution as the electrolyte alone does not make a high capacity battery because the positive electrode utilization rate is low. In order to improve the utilization rate of the positive electrode and to construct a practical sealed nickel-hydrogen storage battery, it is essential to contain lithium hydroxide. In particular, the positive electrode of the nickel foamed porous body filled with nickel hydroxide powder and cobalt powder is inferior to the conventional sintering type in the strength of the substrate, the bonding force between the active material particles, etc. It has a characteristic that it absorbs a large amount and easily expands. In the sintered electrode, the expansion degree is smaller than that of the nickel foam porous body type electrode even if the amount of the electrolytic solution is large to some extent. However, the degree of electrode expansion of the nickel foam porous electrode varies depending on the amount of electrolyte. Further, when lithium hydroxide is contained, the capacity is increased, so that the expansion degree is further increased when the amount of the electrolytic solution is increased. As described above, when the nickel foam porous electrode is adopted, the electrode itself absorbs the electrolytic solution and abnormally expands, but it is necessary to set the amount of the electrolytic solution per Ah to an optimum range. In a battery with regulated positive electrode capacity, lithium hydroxide is included in order to adjust the amount of electrolyte solution per Ah when the utilization factor of the positive electrode is normally output. If lithium hydroxide is not contained, the utilization rate of the positive electrode will decrease and
The amount of electrolytic solution per unit is apparently increased, and an appropriate amount of electrolytic solution cannot be expressed. The positive electrode itself also has a large degree of expansion, leading to deterioration of discharge characteristics. As a matter of course, an increase in the amount of the electrolytic solution causes a rapid increase in the battery internal pressure during charging in addition to the expansion of the positive electrode, which poses a serious problem in terms of safety. On the contrary, the internal pressure of the battery after charging at the 50th cycle increases with an increase in the amount of electrolyte, and sharply increases from 2.6 cc / Ah. This means that gas absorption in the battery is not performed efficiently. If the rising pressure is less than 2 Kg / cm 2 at the 50th cycle as the safe internal pressure for handling, 2.6 cc / Ah is the upper limit of the amount of electrolyte. Particularly in a sealed alkaline storage battery using a non-sintering type positive electrode, the regulation of the amount of the electrolytic solution has a more severe effect, so it is important to find the most preferable range for practical use. The present invention solves this problem in a positive electrode using a nickel foam porous body. Therefore, if it deviates from this range even a little, the internal pressure of the battery and the internal resistance of the battery increase significantly, and it is not practical.

では確認されている。As described above, according to the present invention, since the positive electrode capacity regulates the amount of the electrolyte solution containing lithium hydroxide, even if a battery of a single size and a high capacity of 2.5 Ah is constructed, the internal resistance of the battery is reduced. Therefore, the discharge voltage is 1.25 V or more at the intermediate potential, and the battery pressure is 10 kg / c, which is the operating pressure of the safety valve.
Since it does not rise to m 2 or more, there is no liquid leakage, there is little corrosion of the alloy, and a long life of 500 cycles or more can be expected. At least up to 500 cycles have been confirmed for the same tubular nickel-hydrogen storage battery.

あれば適用可能である。The present invention can be applied regardless of the battery size. For example, the same results as above were obtained in the sizes of AA and AA. Further, it is preferable that the hydrogen storage alloy used for the negative electrode has a hydrogen equilibrium dissociation pressure at room temperature of 1 atm or less because it reduces the hydrogen pressure in the battery. Although a cylindrical sealed battery has been described here, the range of the amount of the electrolytic solution is applicable to any sealed alkaline storage battery having a scale of several 10 Ah to 150 Ah.
