本発明は、鉛蓄電池の電解液注液法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electrolyte injection method for lead-acid batteries.
従来例の構成とその問題点
小型鉛蓄電池は、近年ますます小型化、大容量
(同一形状)が要望され、これに呼応して電槽内
における極板、活物質の占める割合が多くなり、
電解液の入るスペースが、ほとんど無くなつてき
ている。Structure of conventional examples and their problems In recent years, small lead-acid batteries have been required to be smaller and larger in capacity (same shape), and in response to this, the ratio of electrode plates and active materials in the battery case has increased.
There is almost no space left for the electrolyte.
電解液は、セパレータや極板に染み込ませる構

つた。 Since the electrolytic solution is designed to be soaked into the separators and electrode plates, it has conventionally taken 60 to 120 seconds to complete the injection, as shown in Figure 1. When this liquid was forced to be injected to save time, it overflowed from the liquid opening, making it impossible to inject the correct amount of liquid. Therefore, for example, it took about 120 seconds to inject 80 CC , and the electrolyte still overflowed.
A method of injecting sulfuric acid while creating a vacuum inside the battery has also been devised, but from the time sulfuric acid is injected, a chemical reaction begins between the electrode plates and the electrolyte, producing gas. Therefore, even in a vacuum state, due to the gassing phenomenon, the pressure reached the same level as atmospheric pressure in a shorter time than in a vacuum state, and the effect of the vacuum was lost, so that it could not be put to practical use. Furthermore, as a phenomenon occurring in a vacuum, as soon as sulfuric acid was added, violent gassing began and the internal pressure increased, causing the electrolyte to spray out from the injection port, making it impossible to inject an accurate amount.
