BATTERIES WITH PERMANENTLY WET-ABLE FINE FIBER SEPARATORS |
摘要 |
Alkaline batteries are disclosed that advantageously include separators comprising at least one porous layer of fine fibers having a diameter of between about 50 nm and about 3000 nm that provide improved combinations of reduced thickness, dendritic barrier against short-circuiting and low ionic resistance as compared with known battery separators. The fine fibers show improved wet-ability in the alkaline electrolytes.
