OCSiAl together with, Genius, a Chinese company in engineering plastics and new composite materials, develops an advanced engineering solution for battery packs.
They utilize reinforced glass fiber filled polyphenylene sulfide (PPS), with 0.3 wt.% graphene nanotubes replacing 10 wt.% conductive carbon black. The final parts show surface resistivity of 103 Ohm/sq after injection molding and fully meet the high battery standard.
Allows Incorporation of Functional Ingredients
An easy-to-handle pre-dispersed concentrate of nanotubes,
TUBALL™ MATRIX, allows processability and the freedom to incorporate other functional ingredients.
Permanent homogenous resistivity without “hot spots,” retained color, good surface quality, and high performance of the battery pack reduce the assembly costs of battery enclosures, increasing their safety, durability, compliance, and affordability, which are the major drivers on the EV market.
“
In contrast to conventional additives, graphene nanotubes used at an ultra-low effective concentration make it possible to preserve the outstanding chemical and thermal performance of high glass filled PPS, including its dimensional stability at ambient conditions,” says Loyes Zhi, managing director of sales and commercial for Greater China & SEA, OCSiAl Group.
“
What’s more, they preserve the required MFI level and impact viscosity, thereby providing acceptable injectability, which is hard to achieve using multi-wall carbon nanotubes,” adds Zhi.
