Amprius Technologies has unveiled its groundbreaking SiCore™ cell chemistry, poised to redefine energy storage for electric mobility. This innovation utilizes a proprietary silicon anode platform, enabling unmatched energy density and power performance within a single cell. Designed specifically for advanced air mobility, electric vehicles (EVs), and drones, the SiCore cell offers transformative capabilities, such as an industry-leading energy density of 370 Wh/kg and high-power output exceeding 3000 W/kg. By balancing these metrics, Amprius aims to overcome traditional trade-offs between energy and power, enabling superior performance in demanding applications.
The SiCore cell is engineered to excel in high-demand environments, offering rapid energy delivery with discharge rates up to 10C without cooling and 15C with active cooling. This makes it ideal for mission-critical industries like aviation, unmanned aerial systems, and high-performance EVs. Early adopters, such as Teledyne FLIR, anticipate significant operational improvements, including extended mission durations and enhanced performance under rigorous conditions. Amprius emphasizes that the SiCore platform’s versatility allows customers to achieve superior range, speed, and reliability, critical for applications like eVTOL aircraft, which require both high power for takeoff and extended energy for long flight times.
Pre-production samples of the SiCore cell were delivered to select customers in late 2024 for real-world testing, paving the way for commercialization in early 2025. Amprius CEO Dr. Kang Sun and CTO Dr. Ionel Stefan highlight the strategic importance of this innovation, noting its potential to drive widespread adoption of silicon anode technology across rapidly growing industries. With its pioneering advancements, Amprius positions itself as a leader in next-generation lithium-ion batteries, setting new benchmarks for energy storage in electric mobility solutions.
