Arkema is highlighting a range of acrylic and PVDF materials for coating applications inside electric-vehicle and energy-storage batteries.
The company’s Incellion acrylic binder portfolio includes materials for primer coatings and ceramic-based separator layers, complementing its existing Kynar Flex PVDF separator-coating technology. Arkema also offers Incellion acrylic binders for silicon-based anodes and Kynar PVDF products used as cathode binders in lithium iron phosphate battery systems.
Among the separator technologies, Incellion Sp 1252 is an acrylic binder developed for ceramic-coated separators. Arkema says its separator-coating materials are designed to support mechanical stability, electrolyte wettability, adhesion and thermal dimensional stability. The company also offers Incellion Pr binders for current-collector primer coatings.
Arkema says the materials can support higher active-material loading and higher-energy-density cells while addressing manufacturing and durability requirements.
The company is presenting its battery materials at The Battery Show North America, Oct. 12-15 in Detroit. Arkema also recently completed a 15% PVDF production-capacity expansion at its Calvert City, Kentucky, facility as it increases support for battery applications.
Electrode primers and separator coatings are growing functional-coatings applications as battery manufacturers seek higher energy density, improved adhesion and more efficient production processes.
