Vapor pressure barriers for lead-acid batteries for improved water loss performance, separators, systems and methods of manufacture and application thereof

摘要

New or improved lead-acid batteries with vapor pressure barriers and / or improved battery separators as well as systems, vehicles and / or methods of making and / or using them are disclosed herein. In at least selected embodiments, the present disclosure provides new or improved lead-acid batteries having a vapor barrier. In at least selected embodiments, the present disclosure contemplates new or improved lead-acid battery vapor pressure barriers along with new or improved battery separators and / or methods of making and / or using them. In at least selected embodiments, the present disclosure provides a new or improved lead-acid battery having a vapor pressure barrier that reduces water loss from the battery. In at least selected embodiments, a method of reducing the water loss of a lead-acid battery may include providing a vapor pressure barrier, such as an oil layer, in the lead-acid battery together with an improved battery separator.
