The French scientist Nicolas Gautherot observed in 1801 that wires that had been used for electrolysis experiments would themselves provide a small amount of "secondary" current after the main battery had been disconnected. In 1859, Gaston Planté''s lead-acid battery was the first battery that could be recharged by passing a reverse current through it. Planté''s first model consisted of two lead sheets separated by rubber strips and rolled into a spiral. His batteries we…

20.7: Batteries and Fuel Cells

Lead acid battery boiling during charging: this is bad, right?

The reason is that lead-acid batteries normally form bubbles on the plates during charging. And these get big enough and then rise. Some chargers will periodically reverse the charging voltage polarity for a moment in order to force the bubbles loose so as to keep them small, as the bubbles interfere with re-plating lead from solution back onto ...

Lead Acid Battery
