摘要： An exemplary hybrid battery separator is provided with a porous sheet with a folded bottom edge and joined lateral edges that form a pocket. The folded bottom edge may have one or more openings or slits. The hybrid separators of the present disclosure are particularly useful for flat-plate cycling batteries. The separators of the present disclosure may effectively enhance the battery re-chargeability and the backup time. In addition, the separators of the present disclosure may contribute to the reduction of water loss in the battery, lowering the maintenance needs in service. It is expected that batteries having the separators of the present disclosure may be useful in various applications, such as in inverters, golf carts, as well as solar and traction applications.
