PROBLEM TO BE SOLVED: To provide a gastight lead acid battery in which the growth of dendrites is considerably suppresses and the stable electric property is obtained. SOLUTION: The gastight lead acid battery is equipped with either a woven cloth (functional woven cloth) or a non-woven cloth (functional non-woven cloth) 3 having ion exchange capability is placed adjacent to both negative and positive electrodes. With this structure, Pb2+ ion leaked from either the positive electrode 1 or the negative electrode 2 is captured in a good yield in the functional non-woven cloth 3, followed by the reasonable suppression of the growth of dendrites at the negative electrode 2, resulting in a long life lead acid battery with remarkable battery properties. |
