| Zusammenfassung: | The invention relates to a lead acid storage battery negative electrode plate manufacturing process, which comprises: (1) casting to form a plate, (2) stirring to form a paste, and coating the plate with the paste; (3) leaching with an acid; (4) carrying out surface drying, (5) immersing in an acid (the immersing time is 3-30 min), and (6) carrying out curing drying. According to the present invention, with the lead acid storage battery negative electrode plate manufacturing process, the temperature in the battery can be substantially reduced during the internal formation (battery formation) acid-adding charging so as to reduce the dissolving of the negative electrode additive sodium ligninsulfonate in the acid, the negative electrode additive can be easily fixed in the negative electrodelead paste (negative electrode active substance), and the low temperature charging performance of the battery can be substantially improved.
