Abstract
The method for producing plates for batteries according to the present invention comprises: allowing X-rays to penetrate through a supplied core material, thereby calculating the weight of the core material; filling the core material with an active material; then again allowing X-rays to penetrate through the core material, thereby calculating the weight of the filled active material and the core material; calculating the weight of the active material based on the difference in these weights measured; if this weight of the filled active material deviates from a given weight, adjusting the amount of the active material to be filled in the core material, thereby inhibiting variation in the amount of the filled active material; and then drying the core material filled with the active material to make an electrode plate.
