Embodiment 1

[0055] In Example 1, relative to the third area A3, the amount of lead in the first area A1 of the positive electrode grid substrate 21 was set to 1.3 times, the amount of lead in the second area A2 was set to 1.1 times, and the amount of lead in the fourth area A4 was set to 1.3 times that of the third area A3. Set to 1.1 times. In addition, in Example 2, relative to the third area A3, the amount of lead in the first area A1 of the positive electrode grid substrate 21 is set to 1.3 times, the amount of lead in the second area A2 is set to 1.3 times, and the amount of lead in the fourth area A4 is 1.3 times that of the third area A3. The amount of lead is set to 1.3 times. Furthermore, in Example 3, the amount of lead in the first area A1 of the positive electrode grid substrate 21 is set to 1.5 times the amount of lead in the first area A1 of the positive electrode grid substrate 21, the amount of lead in the second area A2 is set to 1.1 times, and the amount of lead in the f...

Abstract

The invention provides a lead storage battery capable of preventing degradation and unevenness caused by grid corrosion of an anode grid substrate, and thus prolonging life; the anode grid substrate is uniformly divided into two parts respectively in up-down and left-right direction so as to form 4 zones; a zone with an ear is the first zone; a zone adjacent to the first zone in the left-right direction is the second zone, and the second zone is opposite to the ear zone of a cathode grid substrate; a zone adjacent to the first zone in the up-down direction is the third zone, and the third zone is far away from the ear zone of the cathode grid substrate; a zone most further away from the ear portion of the anode grid substrate is the fourth zone; compared with the third zone, the lead amount in the first zone is 1.3-1.5 times bigger, and the lead amount of the second and fourth zones are 1.-1-1.3 times bigger.

Description

technical field [0001] The present invention relates to a lead storage battery with a positive electrode substrate, and the positive electrode substrate contains lead as a main component. Background technique [0002] A lead-acid storage battery utilizing a positive electrode plate on a grid-like positive electrode grid substrate composed of a lead-calcium-tin alloy containing lead as a main component is widely used as a maintenance-free control valve type lead storage battery. Filled with paste positive active material. Factors affecting the life of such a valve-controlled lead acid battery include deterioration due to corrosion (grid corrosion) of the positive electrode grid substrate. Deterioration due to grid corrosion can make the conductivity in the grid worse and increase the internal resistance of the battery, and the elongation of the grid due to this side effect can make the combination of the positive grid substrate and the positive active material Deterioration...
