About the battery case material?

The main function of the battery pack case is to carry the battery pack. Protect from damage from external bumps, shocks and extrusions.

1. Steel shell

The steel battery pack shell is the most primitive power battery pack shell material, which is generally welded by cast steel plates.

2. Aluminum shell

The battery pack is made of aluminum, which has the characteristics of easy processing and forming, high temperature corrosion resistance, good heat transfer and electrical conductivity, long service life, flame retardancy, anti-aging performance, and explosion-proof performance.

3. SMC composite material

Sheet molding compound, the main raw materials are composed of GF (special yarn), UP (unsaturated resin), low shrinkage additive, MD (filler) and various additives.

SMC has good electrical properties, chemical corrosion resistance, low thermal conductivity, small expansion coefficient, excellent UV resistance and aging resistance, good fatigue resistance, light weight and high strength.

4. Carbon fiber reinforced composite materials

Carbon fiber composite materials have become an ideal substitute for traditional metal battery pack casings.

5. PC+LFT-D long fiber reinforced thermoplastic material

The excellent flame retardancy, dimensional stability and mechanical properties of the PC material complement each other with the inherent long fiber retention rate of the LFT-D process, which perfectly meets the needs of the battery pack case application.
