FAQs about Principle of hydrogen evolution at the negative electrode of lead-acid battery
How does hydrogen evolution affect battery performance?
Hydrogen evolution impacts battery performance as a secondary and side reaction in Lead–acid batteries. It influences the volume, composition, and concentration of the electrolyte. Generally accepted hydrogen evolution reaction (HER) mechanisms in acid solutions are as follows:
What happens if a lead-acid battery is charged with a carbon electrode?
Under the cathodic working conditions of a Lead–acid battery (−0.86 to −1.36 V vs. Hg/Hg 2 SO 4, 5 mol/L sulfuric acid), a carbon electrode can easily cause severe hydrogen evolution at the end of charge. This can result in thermal runaway or even electrolyte dry out, as shown in Fig. 5.
What happens when a lead acid battery is charged?
Normally, as the lead–acid batteries discharge, lead sulfate crystals are formed on the plates. Then during charging, a reversed electrochemical reaction takes place to decompose lead sulfate back to lead on the negative electrode and lead oxide on the positive electrode.
Why is the discharge state more stable for 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.
Why do lead acid batteries outgass?
This hydrogen evolution, or outgassing, is primarily the result of lead acid batteries under charge, where typically the charge current is greater than that required to maintain a 100% state of charge due to the normal chemical inefficiencies of the electrolyte and the internal resistance of the cells.
How does a lead electrode affect hydrogen gas development?
The high potential voltage (related to the standard hydrogen electrode) of the lead electrodes have a high influence on the hydrogen gas development, particularly if the lead electrode is connected in conductive electrolyte (like sulfuric acid) along with a metal with lower potential voltage.
