    摘要： A manufacturing method for a flexible battery including injecting an electrolyte into an opening of an exterior material accommodating an electrode assembly contained therein and impregnating the electrode assembly with the electrolyte through a pressure difference inside the exterior material; and a sealing step of sealing the opening. Because the electrode assembly provided in the battery can be completely impregnated with an electrolyte, no spot occurs on the surface of a negative electrode filled with the electrolyte. In addition, the flexible battery can prevent or minimize deterioration of physical characteristics that the battery is required to exhibit, even if repeated bending occurs.

    摘要： An automatic and passive battery fluid maintenance system maintains the fluid levels in a battery system by replenishing water as the water is lost from the battery. A reservoir is used to contain a volume of fluid and is mounted above the batteries. Fluid from the reservoir flows into a distribution manifold through a flow regulator. From the manifold the fluid is distributed a vent plug at each battery. The vent plugs are configured to control create a backpressure in the fluid line when the battery fluid level is at an optimum level. As a result of the backpressure, fluid does not flow into the battery through the vent plug. When the fluid in the battery drops below the optimum level, the backpressure is reduced, allowing water to flow until the fluid level of the battery again is at the optimum level.
