Provide membrane technologies for food packaging and battery separator applications.
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.
Bettery Separators
APorous Lithium separator is designed to improve the safety performance of the lithium batteries. Lithium batteries have the highest energy density amount today's commercial battery systems. APorous has developed a thermally stable composite glass and polypropylene battery separator, dimensionally stable up to 150°C.

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.
