Amprius Technologies, Inc. has delivered its new 6.3Ah 21700 SiCore™ cell to a Fortune 500 company in the Light Electric Vehicle (LEV) sector for evaluation.
With an energy density of 315 Wh/kg, the 6.3Ah SiCore™ cell builds on Amprius’ proven technology, delivering over 25% more capacity than a standard 5.0Ah 21700 cell while maintaining a high-power 3C discharge rate. It achieves 800 cycles at 80% depth of discharge (DOD), extending battery lifespan and lowering replacement costs. Designed for seamless integration, its drop-in compatibility allows manufacturers to boost performance without the need for costly system redesigns.
While the initial focus for this 6.3Ah SiCore™ cell is on the LEV market, the high energy density and extended cycle life make it well-suited for a range of applications, including fixed-wing aviation and AI applications such as robotics.
Dr. Ionel Stefan, CTO of Amprius Technologies, commented, “Our new 6.3Ah 21700 SiCore™ cell has attracted strong interest from leading OEM manufacturers because it delivers a significant improvement in battery performance. With commercialization of this cell set for this year, we are excited to offer a high-capacity, long-lasting solution that meets the growing demand for more efficient energy storage solutions across multiple industries.”
Amprius has established manufacturing partnerships to enable large-scale production and support anticipated demand. As interest in high-performance energy storage grows, the company continues to develop battery technologies aligned with broader electrification trends.
