Arkema's Kynar grades designed specifically for lithium-ion cells will be on display at the 12th edition of Batteries 2010, taking place in Cannes from September 29th to October 1st. This international annual event is a key forum for raw materials suppliers, electronic devices suppliers, battery manufacturers, industrial users, environment and recycling specialists and universities to exchange in the fields of batteries and energy storage.
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.
