Technology highlights:
The cell uses EVE's third-generation high-speed stacking (laminating) technology, along with current collector technology and 3T thermal management technology to reduce temperature differential across the cell. It features a 14μm separator with special coating for enhanced safety, and has passed nail penetration testing.

Applications:
Designed primarily for utility-scale energy storage systems (ESS), renewable energy integration, commercial and industrial storage, and long-duration storage applications (4+ hours). A single 628Ah cell delivers roughly twice the energy of a 314Ah cell, and systems using it can reduce cell count, connectors, and BMS collection points by approximately 50% compared to 314Ah-based solutions.
