Porous lead
WebPorosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).. There are many … WebLead-acid batteries are the traditional standard technology for industrial battery solutions. Each cell within the battery consists of alternating plates of lead dioxide and porous lead, submerged in an acidic electrolyte solution which causes an imbalance of electrons between the two plate types. This imbalance is what creates the voltage.
