Plastics are essential as electrical insulators for high voltage battery applications, where resistance to short term exposure to high temperatures from arc events is crucial. Flame retardant PBT and PBT blends are preferred for dimensionally critical components such as pouch cell frames and round cell carriers. For overmolded busbars, PA6 and PA66 with varying glass fiber content and flame retardant additives are used to withstand thermal shock. Thermally conductive grades further enhance performance by promoting even temperature distribution and reducing peak temperatures.

A low-thickness thermoplastic composite battery housing has passed strict thermal runaway testing – proof that lightweight doesn't mean less safe. See what this means for your next EV battery enclosure design.

Not all thermoplastics are created equal when it comes to designing an EV battery. Watch our Tech Talk to see how advanced thermoplastics are being engineered into the next generation of EV batteries: from impact resistance to thermal safety.

Cost, range anxiety, charging speed: the barriers to EV adoption go deeper than the battery cell. High-performance electrolyte additives are quietly solving some of the industry's toughest problems. Here's how.

Battery management and cell monitoring housings need to be flame-retardant, low-warpage and resistant to heat, chemicals and electrolyte vapor. See how Pocan® (PBT) AF4130 is designed for exactly that.

A battery system doesn't need a material choice – it needs an engineering partner who can balance it all. See how Envalior turns EV battery innovation into scalable production, from concept to certification.
