Discover Arkema® Advanced Materials Battery Solutions -- Not all resins are created equal

Arkema provides a series of high performance polymers, which include Kynar® PVDF, Pebax® polyamide elastomer, Rilsan® PA11, and Kepstan® PEKK. These high performance polymer materials, representing some of the world’s highest performing polymers, are specified to use in various demanding applications worldwide across an array of diverse markets from industry to consumer. 

Commercialized in 1965, Kynar® PVDF is designed for extreme environments. Its legacy has been proved by its outstanding track record in use for high durability skyscraper coatings (>50 years), subsea pipes for oil & gas (>25 years), and solar panel backsheet protection (>10 years).

The electrochemical environment in lithium ion battery is extreme as well. It is critical for engineers to design with purpose and caution when in the material selection process, where oxidation and high voltage threaten the integrity of the every material that is exposed.

Discover our Bostik® Adhesive Battery Solutions

Bostik offers a range of high-performance adhesives and sealants solutions and technologies for litium ion battery assembly applications, including HMPSA (hot melt pressure sensitive adhesives), SMP (Silyl Modified Polymers), LPM PA (Low Pressure Molding Polyamide), Butyl, and MMA (methyl methacrylate).  These specialty adhesive and sealant materials, representing some of the world’s highest performing bonding and sealing solution, are specified to use in various demanding applications worldwide across an array of diverse markets from industry to consumer.

The working environment for lithium-ion (li-ion) battery manufacturing and assembly is extreme as well. In the electrification of powertrains, adhesives and sealants have been taking up a key role in the design of battery architectures to develop electric vehicle battery cells, modules and packs. Challenges for automotive battery technologies are to meet performance objectives from longer lifetime, endurance and extended range, operational safety and reliability to cost efficiency.

It is critical for engineers to design with purpose and caution when in the material selection process those challenges needs to be met and where high reliability, process friendly, fast efficiency and better thermal management can generate cost competitiveness.
