Abstract

PURPOSE:To decrease the self-discharge of a battery with its activity retained by specifying the BET surface area of a bromine electrode of a metal-bromine battery. CONSTITUTION:In a bromine electrode, a carbon plastic plate 52 is arranged within the opening 50a of a spacer 50, and a piece of porous carbon fiber knetted cloth 54 serving as an active layer is positioned on one side of the carbon plastic plate 52, then they are heat-bonded through aluminium plates 56a, 56b from both sides. A zinc-bromine battery using an electrode plate having a BET specific surface area of 2.4-6.0m<2>/cm<2> is charged and allowed to stand for 5 hours. In the battery using the electrode having a BET specific surface area of 6m<2>/cm<2>, a large amount of bromine is adsorbed on the active layer and self-discharge is increased during being allowed to stand, and the coulomb efficiency is decreased by about 10%. In the battery using the electrode having a BET specific surface area of 3.5m<2>/cm<2>, the high coulomb efficiency is retained. The battery using the electrode having a BET specific surface area of 2.5-5.0m<2>/cm<2> keeps high coulomb efficiency after the battery was allowed to stand.
