分布されなかったためであると考えられる。As shown in (Table 1), barium sulfate and lignin sulfonate were added by a conventional addition method, or barium sulfate and lignin sulfonate were mixed at a frequency of 20 Hz or 120 Hz. Alternatively, in the method of adding particles in which barium sulfate and lignin sulfonate integrated with each other are passed through a 100-mesh sieve, the discharge time has a large variation of about ± 30 seconds. This is because the barium sulfate and the lignin sulfonate particles are not sufficiently integrated by the conventional addition method or the method of mixing with the frequency of 20 Hz. Further, it is considered that the barium sulfate and the lignin sulfonate were not uniformly distributed in the negative electrode paste because the particles which were once integrated were separated again by the method of mixing with the frequency of 120 Hz.

In a battery in which particles obtained by passing this through a sieve of 200 to 600 mesh are added to the negative electrode active material, the particles are fine and evenly distributed in the paste, so the addition effect can be kept uniform and the discharge time Variation of ± 10
It could be reduced to about a second.

好ましい。Further, particles obtained by integrating barium sulfate and lignin sulfonate and passing them through a sieve having a mesh finer than 600 mesh could not be uniformly distributed in the negative electrode paste due to scattering of the particles. Therefore, it is preferable that the sieve has a mesh size of 200 to 600 mesh.

思われる。As shown in (Table 2), as in the case of high rate discharge characteristics at low temperature, barium sulfate and lignin sulfonate were integrated at a frequency of 30 to 100 Hz to obtain a 200 to 600 mesh mesh. In the battery prepared by adjusting the paste obtained by adding the particles obtained by passing through the sieve to the negative electrode active material,
We were able to greatly reduce the variations in charge and discharge cycles. It is considered that this is also because the reaction of the negative electrode paste was made uniform by the uniform distribution of barium sulfate and lignin sulfonate.

By adding such particles to the negative electrode active material to form a paste, it is possible to reduce variations in low-temperature high-rate discharge characteristics and charge / discharge cycle life characteristics of the lead storage battery.
