Abstract

The invention discloses a deep cycle-resistant lead-acid storage battery plate, which comprises a positive plate and a negative plate. Each of the positive and negative plates is obtained by coating positive plate lead plaster and negative plate lead plaster on a positive plate grid and a negative plate grid and executing the main process steps of curing, formation and fragmentation. The positive plate grid is cast from a Pb-Ca-Sn-Al alloy material comprising 1.25 to 1.35 weight percent of Sn, 0.05 to 0.07 weight percent of Ca, 0.03 to 0.035 weight percent of Al and the balance of Pb and inevitable impurities. The negative plate grid is cast from the Pb-Ca-Sn-Al alloy material comprising 0.15 to 0.25 weight percent of Sn, 0.07 to 0.09 weight percent of Ca, 0.025 to 0.035 weight percent of Al and the balance of Pb and inevitable impurities.

Description

technical field [0001] The invention relates to a battery polar plate and a manufacturing method thereof, in particular to a deep-cycle resistant lead-acid battery polar plate and a manufacturing method thereof. Background technique [0002] The battery plate is the most important core part of the lead-acid battery, which largely determines the electrical performance indicators of a lead-acid battery and the life of the battery. According to the different uses of the battery, the materials and formula manufacturing processes used to manufacture the plates are different. Among them, it is more difficult to make the battery plate that requires the battery to be used in deep discharge cycle for a long time, especially the plate of deep cycle VRLA battery (that is, valve-regulated sealed lead-acid battery) has serious positive plate non-antimony effect and positive plate activity. Problems such as the decay effect of the material and the grid in a short period of time, the sulf...
