Abstract

PURPOSE:To increase the amount of electrolyte holding and decrease the specific gravity of electrolyte to increase corrosion resistance and overcharge performance by increasing height of mat-shaped glass fine fibers from that of plates by a specified value. CONSTITUTION:In a sealed lead-acid battery in which electrolyte is held in mat- shaped glass fine fibers 1, height of the mat-shaped glass fine fibers 1 is made higher 1.2 times or more than that of plates 2 and 3. Thereby, the amount of electrolyte holding is increased by 1.2 times or more compared with conventional types. If the amount of sulfuric acid is made to equal, the specific gravity of it can be decreased by about 5%. Therefore, corrosion of cathode plate is decreased and overcharge life is increased.

素ガスは発生せず、電池は密閉化できることになる。In recent years, the demand for maintenance-free batteries has increased, and a sealed lead-acid battery has been developed in which the cap-shaped glass fibers are impregnated with electrolyte and have the characteristics of no leakage and no need for water capture. . In this type of sealed lead-acid battery, as shown in the following equation, oxygen scum generated on the anode plate is reduced at the three-phase interface between the lead on the cathode plate and the electrolyte, and when the battery is overcharged, oxygen scum is returned to the anode plate. The oxygen generated is
Since the lead sulfate (PbSO,) that is absorbed by the lead sulfate (PbSO,) produced thereby is reduced, hydrogen gas is no longer generated and the battery can be sealed.

。However, in this type of battery, the amount of electrolyte is inevitably reduced by removing the excess flowing electrolyte, and in order to secure the necessary amount of sulfuric acid, the specific gravity r of each electrolyte core is increased. As a result, the anode plate was prone to corrosion, which shortened its lifespan.

If the height of the matte glass fine fibers is increased by 1.2 times or more, the amount of electrolyte retained will also increase by 1.2 times compared to the conventional one, and if the same amount of sulfuric acid is added, the specific gravity will be approximately 5%. It will be lowered.
