Zusammenfassung: | A multilayer non-woven mat for a lead-acid battery includes a first layer of non-woven web of fibers including coarse fibers having an average fiber diameter from about 6 μm to about 25 μm and a second layer of non-woven web of fibers including microfibers having an average diameter from about 0.5 μm to about 5 μm. The multilayer non-woven mat includes a binder configured to simultaneously bind the coarse fibers in the first layer together, the microfibers in the second layer together, and at least some of the coarse fibers in the first layer to at least some of the microfibers in the second layer together. The first layer is configured to absorb an active material of an electrode of the lead acid battery, and the second layer is configured to block the active material of the electrode from passing through the non-woven glass mat. |
