AI Customer ServiceHydrogen 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:
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.
There have been several research studies on the use of activated carbon as a catalyst for hydrogen evolution in the context of Lead-acid batteries. These include: 'Hydrogen evolution inhibition with diethylenetriamine modification of activated carbon for a Lead–acid battery' [50], 'Toward design of synergistically active carbon-based catalysts for electrocatalytic hydrogen evolution' [51], and 'Nitrogen-doped activated carbon as a metal free catalyst for hydrogen production in microbial electrolysis cells' [52].
The materials used in UltraBattery or Pb–C battery for hydrogen evolution have lower overpotentials of hydrogen evolution, especially in acidic electrolyte, which promotes hydrogen evolution and increases the inner pressure, accelerating water loss of the battery. (20, 29)
Separators as source of hydrogen evolution inhibitors This presentation starts with recognizing that a lead-acid battery is able to reach more than 2V open circuit voltage only thanks to the very high hydrogen evolution overpotential on lead electrodes preventing gassing in a fully charged battery.
Watering is the most common battery maintenance action required from the user. Automatic and semi automatic watering systems are among the most popular lead acid battery accessories. Lack of proper watering leads to quick degradation of the battery (corrosion, sulfation....).
