Kev Paub Txog Lead-acid Batteries

Lead acid roj teeb (VRLA) yog cov roj teeb uas nws cov electrodes feem ntau yog ua los ntawm txhuas thiab nws cov oxides, thiab nws cov electrolyte yog sulfuric acid tov. Nyob rau hauv lub xeev paug ntawm txhuas-acid roj teeb, lub ntsiab tseem ceeb ntawm qhov zoo electrode yog lead dioxide, thiab lub ntsiab tseem ceeb ntawm cov electrode tsis zoo yog txhuas; Nyob rau hauv lub xeev them, lub ntsiab tseem ceeb ntawm ob qho tib si zoo thiab tsis zoo electrodes yog lead sulfate.
Lub nominal voltage ntawm ib leeg-cell lead-acid roj teeb yog 2.0V, uas tuaj yeem tawm mus rau 1.5V thiab them rau 2.4V; Nyob rau hauv daim ntawv thov, rau ib leeg-cell lead-acid roj teeb feem ntau txuas rau hauv series los tsim ib tug lead-acid roj teeb nrog ib tug nominal voltage ntawm 12V, raws li zoo raws li 24V, 36V, 48V, thiab hais txog.
