る。Conventional technology Conventionally, anode plates for lead-acid batteries have been made by using pure lead as a raw material and producing lead powder using the ball mill method or the 7-rutin flow method, along with short plastic fibers or carbon, and water and dilute sulfuric acid. A paste-like positive electrode active material obtained by kneading is filled into a lead alloy substrate, and an unformed electrode plate is manufactured through an acid soaking process, an aging process, and a drying process.

量が大幅に低下するという問題点があった。Problems to be Solved by the Invention However, when kneading the above raw materials to make an anode active material, the temperature rises significantly during cross-conducting, especially in the hot summer months. In addition to the production of lead sulfate, reaction (2) also produces tetrabasic lead sulfate.This greatly changes the paste properties, making it difficult not only to fill the lead alloy substrate but also to reduce its capacity as an anode plate. There was a problem in that the value decreased significantly.

く陽極板の容量低下を防止する。Effects According to the present invention, reaction (2) is suppressed due to the presence of lignin as a crystal modifier, so that tetrabasic lead sulfate is not produced (during the crystal growth process, lignin is quickly adsorbed to the crystal surface and This is thought to be because the paste enters inside the crystallization and affects the crystal structure), which not only allows for smooth filling without changing the paste properties of the anode active material, but also prevents a decrease in the capacity of the anode plate. do.
