It has been difficult to use it for maintenance-free batteries and sealed batteries. Therefore, in order to suppress self-discharge and a decrease in electrolyte solution and to achieve maintenance-free, a lead alloy containing no Sb, such as a Pb-Ca alloy containing Ca in an amount of 0.04 to 0.12 wt%, is used.

充分放電できなくなってしまうという問題がある。However, the capacity of a battery using a lead alloy containing no Sb for the positive electrode current collector may decrease earlier than the capacity of a battery using a Pb-Sb alloy. This is because
It is considered that the adhesion between the positive electrode current collector and the active material is deteriorated, and a corrosive layer that easily discharges is formed on the current collector. In any case, a positive electrode current collector containing no Sb is used. In the battery used, there is a problem that the corroding layer of the current collector is discharged and a passive layer is easily formed at the interface between the current collector and the active material, and the active material cannot be sufficiently discharged.

0.1% on the surface of the Pb-Ca alloy current collector containing Ca.
As a method of forming a Pb-Ca-based alloy layer containing 2 to 5 wt% of Ca, a Pb-Ca-based alloy containing 0.04 to 0.12 wt% of Ca is formed on a thick plate (slab) of Pb-Ca-based alloy. ~
There is a method in which foils of a Pb-Ca-based alloy containing 5 wt% of Ca are overlapped and rolled. However, the foil of this alloy composition is very brittle as compared with a Pb-Sb-based alloy, a Pb-Sn-based alloy, and a Pb-Ca-based alloy having a Ca content of 0.12% or less. There has been a problem that the steel sheet may be broken and come off the slab, resulting in a portion where the surface layer is not formed after rolling.
