Lead Acid Batteries
Lead acid battery was invented in 1859 by Gaston Plante, and has been widely used throughout the world for more than 150 years [].At present, all automobiles are equipped with one or more lead-acid battery. As for industrial application, lead-acid batteries have ...
Lead–Acid Batteries
The discharge state is more stable for lead–acid batteries because lead, on the negative electrode, and lead dioxide on the positive are unstable in sulfuric acid. Therefore, the chemical (not electrochemical) decomposition of lead and lead dioxide in sulfuric acid will proceed even without a load between the electrodes.
