Teijin: Battery box development of multiple materials: For EVs and HVs
-Aiming for mass production in 2025-
Teijin:
We have developed a multi-material battery box that combines multiple materials.
Batteries for EVs and HVs.
Continental Structural Plastics (CSP):
It was jointly developed with Continental Structural Plastics (CSP), a US group company that handles composite material products.
Aim to start mass production from 2025.
New battery box:
A multi-material housing that uses composite material (FRP) and metal in the right place.
Major features:
SMC (Sheet Molding Compound) using a press molding machine
It can be integrally molded even with complicated shapes, contributing to optimization of manufacturing costs.
Ensures fire resistance, dimensional stability, and corrosion resistance.
It is also possible to add electromagnetic wave shielding to the tray and cover.
Multi-materialization:
On the other hand, metal is used for the frame to ensure the rigidity and impact resistance of the entire housing.
By using multi-material, the weight is the same as that of aluminum.

Continental Structural Plastics’ Advanced Technologies Center Unveils Lightweighting, Battery Enclosure and Materials Innovations
Continental Structural Plastics
Auburn Hills, Michigan
December 9, 2020
Continental Structural Plastics (CSP), along with its parent company Teijin,
today unveiled an innovative honeycomb Class A panel technology and an advanced, multi-material EV battery enclosure
that can be molded in any enclosure is 15% lighter than a steel battery box.
Although it is equal in weight to an aluminum enclosure, the CSP enclosure offers better temperature resistance than aluminum, especially when CSP’s proprietary phenolic resin system is used.
These component technologies
were developed at the company’s new Advanced Technologies Center located on Harmon Road in Auburn Hills, Michigan.
This Advanced Technologies Center is CSP’s second R&D facility in the city.
