摘要：
Lead-acid battery (LAB) has a huge world market in both energy storage and power supply. However, most LAB failures are caused by the serious corrosion of positive grids. To this, we propose an electrochemical prepassivation strategy to form a compact interphase on the lead-alloy grid surface composed of lead oxides and lead sulfate, exactly the same as lead paste. The results show that the corrosion resistance of pre-passivated lead alloy is improved due to the inhibition of vertical growth of corrosion layer, providing a feasible solution to prolong the service life of LAB.
