(NYSE: AMPX) is a U.S.-based developer of high-energy-density lithium-ion batteries that leverage silicon anode technology to deliver performance levels beyond conventional graphite-based cells. The company’s batteries are designed to offer industry-leading gravimetric energy density, enabling longer run times and reduced weight for portable power applications. Amprius blends advanced materials science and scalable manufacturing processes to commercialize next-generation battery solutions. At the core of Amprius’ product portfolio are cylindrical and prismatic cells that employ a proprietary silicon nanowire anode, which supports high charge/discharge rates while maintaining cycle life. These cells find use in markets with stringent energy and weight requirements, including unmanned aerial systems, defense electronics and high-performance electric vehicles. The company also provides custom battery modules and packs for specialty applications where standard off-the-shelf cells are unable to meet demanding form-factor or endurance criteria. Headquartered in Fremont, California, Amprius operates its pilot production line in the same region and works closely with government agencies, aerospace contractors and industrial partners across North America. Its domestic manufacturing footprint underscores a commitment to secure supply chains for strategic applications, while ongoing R&D efforts aim to further enhance energy density, safety and cost competitiveness. Originally spun out of university-driven materials research, Amprius continues to invest in next-generation silicon materials and cell architectures. The company’s engineering team collaborates with industry and academic partners to scale its technology from laboratory demonstrations to full-scale production, positioning Amprius as a potential leader in high-performance battery innovation.AI Generated.
