Prismatic Battery Cell Caps

Battery Cell Caps

In prismatic battery cells, the cell cap is critical to overall safety and reliability. Freudenberg Sealing Technologies’ Battery Cell Caps securely seal and electrically isolate the cell while enabling controlled filling, pressure management, and robust performance throughout the entire battery lifetime.

Battery Cell Caps Advantages (BCC)

Prismatic Battery Cell Envelopes

  • Materials Integrity and Compatibility:

    The materials used for our battery cell caps are carefully developed and selected to ensure compatibility with a diverse range of electrolytes, guaranteeing no contamination that could disrupt the battery's chemistry.

  • Safety Standards:

    Materials are certified according to UL 94 V0, which is one of the most stringent flammability standards.

  • Sustainability:

    The battery cell caps' PFAS-free nature affirms the product's sustainability, aiming to meet long-term environmental goals. This ensures compliance with regulatory requirements and demonstrates FST's continuous commitment to sustainability.

  • Material Development – Innovation and Performance:

    A specific EPDM has been engineered to meet superior compatibility performance with electrolytes over FKM.

  • Sealing and Mechanical Durability:

    The sealing component is designed to ensure perfect tightness and robust compression to withstand variable operating conditions, thereby enhancing the overall reliability of the cell.

  • Enhanced structural integrity:

    Reliable welding solutions are tested under severe conditions to assess their mechanical resistance to peak and fatigue loads, ensuring the durability of the cell.

Commitment to Innovation and Quality in Battery Technology

Incorporating these details, FST’s cell products not only advances battery cell manufacturing but also ensures that every aspect, from safety to sustainability, is addressed, reinforcing FST’s commitment to innovation and quality in battery technology.
