PURPOSE:To provide a method for manufacturing a negative electrode plate for a lead acid battery wherein barium sulfate and lignosulfonic acid salt can be integrally distributed uniformly in a total unit of negative electrode paste in order to reduce unevenness of a high rate discharge characteristic and a charge/discharge cycle life characteristic at a low temperature of the lead acid battery. CONSTITUTION:Barium sulfate and lignosulfonic acid salt are mixed by a fixed proportion and given 30 to 100Hz vibration to integrally form the barium sulfate and the lignosulfonic acid salt. Next, this integral material passes through a 200 to 600mesh screen, and obtained fine particles of fixed range are added to a negative electrode active material to adjust negative electrode paste. By this method, the barium sulfate and the lignosulfonic acid salt can be uniformly distrubuted in a total unit of the negative electrode paste, and unevenness of a high rate discharge characteristic and a charge/discharge cycle life characteristic of a lead acid battery can be reduced at a low temperature. |
