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.

摘要： The present invention provides an aluminum electrolytic capacitor having a cathode, an anode and an improved spacer comprised of polymeric nanofibers. The nanofiber spacer offers low ionic resistance, desirable barrier properties and high electrolyte absorption. The use of the improved spacer results in devices having higher capacitance, lower ESR, less heat generation and improved capacitor manufacturing efficiency.

摘要： A battery separator for a lithium-ion secondary battery is a microporbus membrane with an adjuvant. The microporous membrane is made of a thermoplastic, and has a thickness of 25 μm or less. The adjuvant, in an effective amount, is mixed into the membrane or coated thereon. The adjuvant is a material adapted to reduce or eliminate energy concentrations around the separator. The energy concentration is sufficient to initiate a reaction of the components of the lithium ion secondary battery.
