The application of FRP pultruded profiles in energy storage systems and battery packs

FRP pultruded profiles are widely used in new energy vehicle batteries and energy storage industries due to their advantages of light weight, high strength, electrical insulation, corrosion resistance, and design flexibility. With strength comparable to steel and only one‑quarter to one‑fifth the weight, they significantly reduce weight to extend driving range and improve energy storage capacity.

In automotive batteries, they are applied in battery pack enclosures, frames, module supports, and cooling components. In energy storage, they serve in battery cabinet structures, PV‑energy storage components, and fire safety parts. Practical cases show weight reduction of 40%–50%, along with lower leakage risks and operation and maintenance costs.

Future development will focus on high‑performance materials, multi‑functional integration, and intelligent manufacturing, while applications require performance matching, strict process control, and relevant industry certifications.
