n 2006, Porous Power Technologies was formed around a new microporous membrane material designed specifically for use as a lithium-ion battery separator. At that time, most battery separator materials were originally intended for other applications and adapted when the lithium-ion market began to develop. The companyâ€™s founders saw an opportunity to offer better performing separators and developed its proprietary polyvinylidene fluoride (PVDF) technology for commercialization over the next five years. In 2011, Porous Power formed a strategic partnership with the high-performance fiber-based materials company Ahlstrom. The billionEuro-a-year-Finnish company, which now has a 49% stake in Porous Power, specializes in manufacturing nonwoven fabrics - one of the components in the separators. The companyâ€™s initial products are available for earlystage evaluations, with over 30 customers around the world at different stages of testing. On January 1st, 2014, Porous Power will launch its next generation of safety-enhanced, commercially available product - a ceramic-grade PVDF separator.
