LEAD-ACID BATTERY SEPARATOR RIB FOR IMPROVED ELECTROLYTE SUPPLY AND DIFFUSION NEGATIVE PLATE

摘要

The present invention relates to a lead-acid battery having a separator wherein a rib for negative plate electrolyte supply and diffusion is formed. In the lead-acid battery including a plate group wherein a positive plate and a negative plate are arranged across a separating plate, the present invention includes the separator wherein the rib for negative plate electrolyte supply and diffusion having a charge and discharge support rib which is separately arranged on one side of the separating plate touched with the surface of the negative plate at regular intervals and supplies and diffuses an electrolyte through an electrolyte moving path is formed. Therefore, the growth of an anode material can be suppressed by maintaining a compact rib distance and the charge and discharge efficiency of a negative pole can be improved by easily supplying and diffusing the electrolyte through the small space between ribs.
