One of the electrodes is composed of metallic lead, the other of porous lead dioxide.
ECONOMIST: Einstein and car batteries
That has the effect of making metallic lead less electropositive (ie, more electronegative) than classical theory indicates it should be which would tend to make the battery worse.
In the parlance of chemists, metallic lead is electropositive.
They're typically made of a metallic weave that can include carbon, lead and potassium.
