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.
期刊介绍：
Electrochimica Acta is an international journal. It is intended for the publication of both original work and reviews in the field of electrochemistry. Electrochemistry should be interpreted to mean any of the research fields covered by the Divisions of the International Society of Electrochemistry listed below, as well as emerging scientific domains covered by ISE New Topics Committee.
