The discharge capacity at low temperatures below ℃ is smaller than that at room temperature, and it has been desired to improve engine starting performance in winter or in cold regions. Also, when using portable equipment.

となるのを補い、低温時の充電効率を向上させる工夫が
なされていた。In batteries for portable video movies and the like that are used outdoors in the winter, it has been desired to improve the reduction in discharge capacity at low temperatures. In response to this demand, efforts have been made to improve charging efficiency at low temperatures. For example, during constant voltage charging, the charge control voltage during low-temperature charging is set higher than that at room temperature, and the charge control voltage is increased by -25 to 30 my/min.
It has been devised to provide negative temperature characteristics similar to deg and cells to compensate for insufficient charging and improve charging efficiency at low temperatures.
発明が解決しようとする課題
しかし、上記のような従来からの構成では、電池を充電
する際の雰囲気温度を検知するために。Problems to be Solved by the Invention However, in the conventional configuration as described above, it is difficult to detect the ambient temperature when charging a battery.
充電器にサーミスタ等の感温素子を設けなければならず
、充電器設計上の制約が大きかった。The charger had to be equipped with a temperature sensing element such as a thermistor, which placed significant restrictions on the charger design.
本発明の目的は上記のような問題点を解決し、充電器の

、低温時の放電時間の増大をもたらそうとするものであ
る。The purpose of the present invention is to solve the above-mentioned problems, to improve the charging efficiency of the lead-acid battery itself without improving the charger, and to increase the discharge time at low temperatures. .

との両者を同時に電池内に有する鉛蓄電池とした。Means for Solving the Problems In order to achieve the above objects, the present invention provides lead-acid batteries with interfaces of perfluorosulfonates represented by C, F, ..., So, M (M is an alkali metal). Contains a surfactant alone or combines this surfactant with a mercapto group (-S
A lead-acid battery containing both an aromatic compound having H) and an aromatic compound containing the compound at the same time was prepared.

荷を有することが難しいため、電池の充放電反応の効率
が低下することになる。In a working lead-acid battery, it is recognized that oxygen gas generated during charging is generated in the positive plate, and a portion of it remains in the pores formed by the active material particles. Further, in a sealed lead-acid battery, oxygen gas generated at the positive electrode is absorbed by the negative electrode and converted into lead sulfate, so that a portion of the oxygen gas remains as gas pockets within the pores formed by the negative electrode active material particles. These so-called active material particles having poor wettability with an electrolytic solution have difficulty in having an electric charge on their surfaces, resulting in a decrease in the efficiency of the charge/discharge reaction of the battery.

、パーフルオロスルホン酸塩からなる界面活性剤を電解
液中に含む場合、活物質粒子の形成する０、０１〜１μ
ｍ程度の細孔内の電解液の濡れ性の向上に寄与し、電池
の放電容量の増大ならびに充電効率の向上に作用する。The electrolyte contains a surfactant made of perfluorosulfonate, which functions stably in the sulfuric acid acidic electrolyte in the battery and is relatively stable even in the presence of strong oxidizing agents such as lead dioxide. In this case, the active material particles form 0.01~1μ
It contributes to improving the wettability of the electrolytic solution in the pores of about m size, and works to increase the discharge capacity of the battery and improve the charging efficiency.
また、この種の界面活性剤は、それ自身単独で機能する
が、同時にメルカプト基を有する芳香族化合物を有する
場合、その効果は促進される。界面活性剤によって電解
液と活物質の濡れ性が向上し、同時に上記芳香族化合物
の化学吸着ならびに物理吸着が促進されることになる。Further, although this type of surfactant functions by itself, its effect is enhanced when it also contains an aromatic compound having a mercapto group. The surfactant improves the wettability between the electrolytic solution and the active material, and at the same time promotes chemical adsorption and physical adsorption of the aromatic compound.
たとえば、メルカプト基を有する化合物は、鉛蓄電池に
おける硫酸酸性の電解液中で、プロトンと反応してカチ
オンを生じると考えられる。For example, it is thought that a compound having a mercapto group reacts with protons to generate cations in a sulfuric acid acidic electrolyte in a lead-acid battery.

こで生じたカチオンは正極（カソード）に吸着し、水素
発生反応を減少させ、負極板上での水素過電圧を小さく
することができると考えられる。RS H+ t(''; pyRS H2R: alkyl group It is thought that the cation generated here is adsorbed to the positive electrode (cathode), reducing the hydrogen generation reaction and reducing the hydrogen overvoltage on the negative electrode plate.
すなわち、カチオンによる物理吸着によって、極板表面
は負の電荷をもつので、負極（アノード）での反応に影
響しないままＨ＋の放電反応を促進させることができる
ため、電池の放電反応の進行には何ら障害とならない。In other words, the surface of the electrode plate has a negative charge due to physical adsorption by cations, so it is possible to promote the H+ discharge reaction without affecting the reaction at the negative electrode (anode). There is no obstacle.
一方、十分に吸着がおこれば、二重層を通しての電荷の
移動が妨げられ、充電時に負極板の電位を貴にすること
ができる。しかも、これらの作用は、界面活性剤により
、電解液の濡れ性が改善された場合に効果が大きい。On the other hand, if adsorption occurs sufficiently, the movement of charges through the double layer is hindered, and the potential of the negative electrode plate can be made noble during charging. Moreover, these effects are more effective when the wettability of the electrolyte is improved by the surfactant.
上記のように、負極板の充電時の分極を小さくできるた

圧が小さくなった分だけ充電制御電圧を低くしても同様
の充電効率が期待できる。また、従来と同様に、充電制
御電圧に負の温度特性をもたせた場合には、充電効率の
向上をはかることができる。As mentioned above, since the polarization of the negative plate during charging can be reduced, when charging using the voltage control method, the same charging efficiency can be expected even if the charging control voltage is lowered by the amount that the overvoltage of the negative plate is reduced. . Further, as in the conventional case, when the charging control voltage has a negative temperature characteristic, charging efficiency can be improved.
また、芳香族化合物としてのメルカプタンの解離により
、カチオンを生じやすくするため、電解液中に解離しや
すいアルカリ金属塩の存在する場合、上記効果は相乗さ
れる。Further, since cations are easily generated by dissociation of mercaptan as an aromatic compound, the above effects are synergized when an alkali metal salt that is easily dissociated is present in the electrolytic solution.

着、化学吸着の作用を向上させることができる。As mentioned above, by including a perfluorosulfonate surfactant alone in a lead-acid battery, or by simultaneously including this surfactant and an aromatic compound having a mercapto group, wetting of the electrolyte of these compounds can be improved. It can improve the physical adsorption and chemisorption effects.
すなわち、これらの作用により、鉛蓄電池の正負活物質
の利用率の向上をはかると共に、負極板の水素過電圧を
小さくすることができる。このため、従来の電圧制御に
よる充電方法においても、充電効率の向上をはかること
ができる。That is, by these effects, it is possible to improve the utilization rate of the positive and negative active materials of the lead-acid battery and to reduce the hydrogen overvoltage of the negative electrode plate. Therefore, even in the conventional charging method using voltage control, charging efficiency can be improved.
