Arkema's Kynar grades designed specifically for lithium-ion cells will be on display at this year's Advanced Automotive Batteries Conference. This annual event is a forum for international automakers, their suppliers and related stakeholders to meet and discuss the latest in energy storage technology for vehicle electrification. For the first time, it takes place in Europe, in Mainz (Germany) from February 2-5, 2010.
Of special interest will be Arkema's new binder for lithium-ion batteries, Kynar HSV 900 PVDF, a high molecular weight resin that provides improved adhesion with reduced loading in electrode constructions. This grade enhances the performance of both phosphates and metal oxides.
Kynar polyvinylidene fluoride (PVDF) resins are highly stable polymers that offer an exceptional balance of performance properties. From the beginnings of lithium technology, Arkema has worked closely with scientists to design batteries with higher charge density. From this has come Kynar and Kynar Flex resins that are excellent polymers for use in both polymer and liquid cell lithium batteries.
- Kynar and Kynar Flex resins offer key advantages compared to other polymeric binders:
- exceptional purity, which avoids interference with electrochemical reactions,
- high electrochemical, thermal and chemical stability,
- ease of processing,
- excellent adhesion within electrodes.
As a leading producer of PVDF, Arkema has over 40 years experience in coating, film and polymer technologies.
