Studies of the pulse charge of lead-acid batteries for PV applications: Part I. Factors influencing the mechanism of the pulse charge of …
Another application of the pulse chare is its use in the formation of lead-acid battery positive and negative plates [20], [21]. The results show that the pulse current accelerates the formation process (electrochemical conversion of PbO, 3BS/4BS and PbSO 4 into Pb and PbO 2 ) and increases its faradic efficiency, i.e. decreases the rate of the …
What is a Lead-Acid Battery?
Lead-acid batteries are one of the oldest types of rechargeable batteries and have been around since 1859 when they were first invented by the French physicist Gaston Planté. These batteries are still widely used today due to their low cost and high reliability. They ...

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.
