AURUM thermoplastic polyimide offers Tg of 245 C

Electrical breakdown of high-temperature insulation materials can be prevented by using thermoplastic polyimide (TPI), a high-performance polymer. This is important with the transition to electric vehicles, with polymers that offer higher electrical and thermal properties being sought. To enable faster charging and travel over longer distances, electrical breakdown must be prevented by high-temperature insulation materials.

LFP cells charge in six minutes

DESTEN has developed the first Lithium Iron Phosphate (LFP) cell that can charge in just six minutes at 6 C writes Nick Flaherty. The 160 Wh/kg pouch cell developed by DESTEN is capable of charging from 20% to 80% SOC in six minutes at a charging rate of 6 C. Moreover, the LFP chemistry means the cell is intrinsically safer than lithium ion cells.
