| Abstract: | In order to obtain the cause and the mechanism of dendrite short circuit that took place in valve-regulated lead acid (VRLA) batteries, two kinds of batteries were taken for over-discharge experiment with small current and the morphologies of the separators in the batteries (before) and after over-discharge were observed by scan electron microscopy. The results indicated that the battery assembled by thinner separator was susceptible to dendrite short circuit. The reasons of dendrite short circuit in VRLA (batteries) were discussed. |
