摘要： A separator for a lead acid battery is a porous membrane having a positive electrode face and a negative electrode face. A plurality of longitudinally extending ribs, a plurality of protrusions or a nonwoven material may be disposed upon the positive electrode face. A plurality of transversely extending ribs are disposed upon the negative electrode face. The transverse ribs disposed upon the negative electrode face are preferably juxtaposed to a negative electrode of the lead acid battery, when the separator is placed within that battery.

摘要： Disclosed are an electrolyte membrane for a lithium-air battery, a method of manufacturing the same, a cathode for a lithium-air battery, a method of manufacturing the same, and a lithium-air battery including the electrolyte membrane and the cathode. Particularly, the lithium-air battery includes i) an electrolyte membrane, which is manufactured using an inorganic melt admixture including two or more nitrogen-oxide compounds and thus may have a very low eutectic point, and ii) a cathode, which is manufactured by reducing a metal at a fast speed on a carbon material. As such, the lithium-air battery is capable of stably operating even at low temperatures and providing high power output.
