How to sample the temperature of lead-acid batteries

In fully charged condition of the positive plates, a dense layer of PbO 2 protects the positive grid from rapid anodic attack (Fig. 2).The interface between the metallic (lead alloy) grid and the PbO 2 corrosion layer is thought to comprise a very thin interlayer, having a nominal composition of PbO x, whereby x has a value of 1–1.5. This interlayer …
