め、早期寿命の大きな原因となる。Problems to be Solved by the Invention In lead-acid batteries that use lead powder as a paste paste for the positive electrode, which has the characteristics described above, β-
Since PbO2 is produced raw, it is highly reactive. Although this is good for improving the utilization rate of the active material when using lead-acid batteries, the active material of the positive electrode plate begins to soften and fall off at an early stage. In a lead-acid battery using an expanded lattice, the adhesion between the lattice and the active material interface deteriorates, which is a major cause of premature service life.

量係混合させたものを用いるものである。Means for Solving the Problem In order to solve this problem, the present invention uses lead powder PbO (RED) and metal PbO as a paste raw material for lead-acid batteries.
A composition consisting of PbO (YELLOW) mixed in an amount of 10 to 30% by weight is used.
作 用

。Effect: According to this configuration, the positive electrode active material after chemical formation is α-P.
This α-PbO2 has a large amount of bo2, and while this α-PbO2 has excellent conductivity, its reactivity is also lower than that of β-PbO2, making it difficult for the active material to soften and fall off. Therefore, the adhesion at the interface between the lattice and the active material remains strong over a long period of time.
