ている。2. Description of the Related Art In recent years, there has been a strong demand for higher capacity and longer life of lead-acid batteries using a paste-type positive electrode plate. In order to increase the capacity of the lead storage battery, it is effective to increase the porosity of the active material layer of the positive electrode plate. However, when the porosity of the active material layer of the positive electrode plate is increased, the active material layer easily falls off from the lead alloy lattice used as the current collector, and as a result, the life is shortened. Has been recognized.

る。As a technique for increasing the capacity and extending the life of a lead storage battery, a technique for improving the physical properties of an active material layer of a paste-type positive electrode plate is being studied. In other words, the 4PbO.P with large crystals is added to the active material layer of the paste-type positive electrode plate in the unformed state.
After generating bSO 4 (hereinafter referred to as tetrabasic lead sulfate),
This is a method in which the skeleton of lead dioxide (PbO 2 ) is lengthened by chemical conversion to improve the adhesion strength between the lattice and the active material layer.

られている。[0004] Like the tribasic lead sulfate, the above-mentioned tetrabasic lead sulfate is converted to lead dioxide when it is formed. However, the tetrabasic lead sulfate has a smaller volume expansion coefficient during the formation than the tribasic lead sulfate. It is known that the skeleton hardly collapses even by chemical formation. As a result, it is considered that the adhesion strength between the lattice body and the active material layer is improved, and the life of the lead storage battery can be extended.
