German companies Lanxess and Hella have developed a highly flame retardant , shrink and warp - resistant compound for use in automotive battery systems and photovoltaic plugs and sockets called Pocan AF4130 . The novel compound functions as housing modules for fuel - cell monitoring units ( CMU ) and a battery management unit ( BMU ) , and combines polybutylene terephthalate and acrylic acid - styrene - acrylonitrile , is 30 % glass fibres by weight , plus it has a halogen - based flame retardance package . Currently , the flat devise is part of a lithium - ion battery system for a German electric car .
German companies Lanxess and Hella have developed a highly flame retardant, shrink and warp-resistant compound for use in vehicle battery systems and photovoltaic plugs and sockets called Pocan AF4130. The novel compound functions as housing material for two-cell monitoring units (CMU) and a battery management unit (BMU), and combines polybutylene terephthalate and acrylic ester-styrene-acrylonitrile, is 30% glass fibres by weight, plus it has a halogen-based flame retardance package. Currently, the flat devise is part of a lithium-ion battery system for a German sports car.
