Provide membrane technology for the battery separator, medical applications, food safety and processing.
Film Product Technology
The battery industry has also gone through rapid changes within the last fifteen years. Portability of electronic equipment demanded higher performance and longer run time of batteries. APorous has been able to identify technology gaps created by that change and was able to designed permeable membranes (or separators) to improve the battery performance.
A second separator product is designed to improve the safety performance of the lithium batteries. Lithium batteries have the highest energy density amount today's commercial battery systems, however a major concern is the batteries' safety. These batteries may explode under certain abusive conditions. APorous has developed a thermally stable composite glass and polypropylene battery separator, dimensionally stable up to 150 C to minimize these safety failure modes.
ALKALINE BATTERY SEPARATOR NONWOVEN APOROUS
Thickness (mil) 6 to 8 1.5
Pore size (microns) 30 0.1
Electrical Resistance (mohm-cm.dq.) 35 to 50 25 to 60
Wet-out (seconds) <1 <1
produced by APorous reduced the thickness of the separator from 6 mils down to 1.5 mils for alkaline and button cell uses. The pore size reduced from 30 microns down to 0.1 micron thus eliminated cell shorting. The new separator allowed an increase of active material and increased cell rate capability. This alkaline separator is suitable for battery systems such as zinc-air, silver-zinc and alkaline manganese-zinc.
