Note that a lead storage battery using a clad-type positive electrode plate has a feature that it has a long life. Recently,

状を用いると芯金の集電性が低下するために、高率放電
特性が低下するという問題点がある。In order to reduce the cost of a lead-acid battery using a clad-type positive electrode plate, the number of tubes used is reduced by using tubes having an elliptical cross section instead of conventional tubes having a circular cross section. A method is conceivable. As will be described later, when an elliptical tube is used, the space between each tube where the active material is not filled can be reduced, so that the low-rate discharge characteristics are improved. However, when this shape is used, there is a problem that the high-rate discharge characteristics are reduced because the current collecting performance of the core metal is reduced.

う問題点がある。As a means for improving the current collecting property of 1), a method of increasing the thickness of the core metal of the clad type positive electrode plate can be considered. However, when this method is used, since the volume of the clad type positive electrode plate is limited, the amount of the active material that can be filled is reduced, and as a result, there is a problem that the discharge capacity is reduced.

As a result, there is a problem that the life of the lead storage battery is shortened because the core metal portion is corroded and damaged.

However, when this method is used, there is a problem that the silica fine powder moves to the lower part of the lead storage battery during use and its effect is lost when used for a long time.
