Semi-flooded lead acid battery cell |
摘要 |
A lead acid storage battery cell having a sealed housing in which a positive electrode and a negative electrode are immersed in a liquid electrolyte. The negative electrode is partially exposed to a gas space within the battery cell housing. A pressure relief valve allows excess gas to escape the battery cell while preventing air from outside the cell from entering the gas space. Exposing a section of the negative plate to oxygen gas that evolves within the battery and collects in the gas space reduces water consumption of the cell and extends the maintenance-free life of the battery. The addition of a catalyst to recombine oxygen and hydrogen offers further improvement.
