Abstract

The corrosion of positive grids limits the lifetime of lead-acid batteries. In this study, the corrosion behaviors of PbSrSnAl alloys were investigated. The addition of Sr significantly increases the strain of the grid alloy, and elevates the oxygen evolution potential is raised from 1.863 V to 1.879 V. In addition, the corrosion rate of the PbSrSnAl alloy is reduced from 0.432 to 0.396 mg h−1 cm−2, as Sr changes the microstructure of the corrosion layer on the alloy surface. This study proposes a promising strontium-containing lead alloy that could extend the working life of lead-acid batteries.
