摘要

正极栅的腐蚀限制了铅酸电池的使用寿命。本研究对PbSrSnAl合金的腐蚀行为进行了研究。Sr的加入显著提高了栅格合金的应变，使析氧电位由1.863 V提高到1.879 V。此外，由于锶改变了合金表面腐蚀层的组织，PbSrSnAl合金的腐蚀速率从0.432 mg h−1 cm−2降低到0.396 mg h−1 cm−2。本研究提出了一种有望延长铅酸电池使用寿命的含锶铅合金。

Corrosion resistance of PbSrSnAl positive grid alloys for lead-acid batteries

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.
