Continuous fiber for bottom cover of new energy battery cabinet

4 FAQs about [Continuous fiber for bottom cover of new energy battery cabinet]

What is a fiber-reinforced composite battery cover?

In 2025, several high-profile OEMs— Xiaomi EV, Hyundai Mobis, and BYD —announced expanded use of fiber-reinforced composite lids in their battery enclosures. These covers are typically made using glass fiber or carbon fiber fabrics, paired with flame-retardant epoxy, phenolic, or thermoplastic resins, offering substantial advantages over metal.

Why should you choose a fiber composite battery enclosure?

The excellent properties of the fiber composite construction make the battery enclosure a supporting element of the vehicle structure. We accompany you in all stages of your product development: from planning and conception to product completion and serial production in automotive quality and high volumes – and all this at attractive costs.

What is a carbon fiber Zn-ions structural battery composite?

A carbon fiber Zn-ions structural battery composite is fabricated with epoxy-based binder optimized structural electrode and high-performance solid-state electrolyte, which achieves high energy density and mechanical strength (Fig. 1).

What are composite battery covers?

Composite battery covers are engineered to reduce weight by as much as 60% compared to aluminum, significantly enhancing EV range and energy efficiency. Beyond lightness, their low thermal conductivity and inherent flame resistance help delay thermal propagation—a key factor in meeting safety standards like UN-ECE R100 and GB 38031.
