Lithium Block™ manufacturing and module handling
How Lithium Block is Made
Why ultrasonic wire-bonding, how it differs from tab/resistance welding, and what it unlocks in pack design.
Precision Ultrasonic Bonding
Our ultrasonic wire-bond process creates low-impedance connections on both anode and cathode. It enables compact packaging and acts as cell-level protection for localized fault isolation.
- Ultrasonic frequency: 60kHz for optimal energy transfer
- Controlled bonding force ensures consistent connection quality
- Real-time monitoring validates each bond formation
Metallurgical Bond Formation
Each wire bond creates a true metallurgical connection through atomic-level diffusion between the aluminum wire and cell terminal. This process eliminates the need for solder or mechanical fasteners, resulting in superior electrical and thermal performance.
- Contact resistance: <50 microohms per bond
- Bond strength exceeds 15N pull force specification
- Temperature cycling validated: -40°C to +85°C
Production-Ready Module Assembly
The completed lithium block module features multiple parallel wire bonds that distribute current evenly across all cells. Our manufacturing fixture ensures precise positioning and consistent bond placement, enabling scalable production while maintaining the highest quality standards.
- Parallel bond architecture maximizes current capacity
- Automated quality inspection validates every connection
- Production traceability ensures consistent performance
