Amprius Unveils Revolutionary 450 Whkg Lithium-Ion Battery For Critical Defense Applications
Amprius Technologies, Inc. (NYSE: AMPX) has made a significant breakthrough in the field of lithium-ion batteries with the launch of its 450 Wh/kg SiCore battery, designed specifically for mission-critical applications in aviation and defense. This cutting-edge technology marks a major milestone for the company, which has been working tirelessly to push the boundaries of energy density and scalability.
At the heart of the SiCore battery is Amprius’ proprietary silicon anode platform, which delivers extended endurance and payload capacity. The new cell boasts an impressive 950 Wh/L energy density, making it one of the most energy-dense lithium-ion cells on the market. This means that aircraft and drones equipped with the SiCore battery can fly for longer periods, carry heavier payloads, and operate in a wider range of environments.
The SiCore battery is specifically designed to meet the needs of high-altitude platform stations (HAPS), medium-altitude platform stations (MAPS), and unmanned aerial vehicles (UAVs). These applications require maximum endurance and minimal weight, making the SiCore battery an ideal choice. With its compact design and production-ready format, the battery can be easily integrated into a variety of systems, from small drones to large aircraft.
One of the key benefits of the SiCore battery is its ability to provide up to 80% more energy than traditional lithium-ion cells using graphite anodes. This means that aircraft and drones equipped with the SiCore battery can fly for longer periods, reducing the need for frequent recharging and minimizing downtime. Additionally, the battery’s extended endurance and payload capacity make it an attractive choice for applications where weight is a critical factor.
Scalability is another major advantage of the SiCore battery. Amprius has partnered with a global contract manufacturing network that provides gigawatt-hour-scale production capacity, making it possible to meet anticipated demand. The company expects to receive UN38.3 certification – required for air transport of lithium-ion batteries – within the current quarter, and volume shipments are expected to follow shortly thereafter.
The SiCore platform was first introduced in January 2024 to support both high-energy and high-power applications in a single format. With the new 450 Wh/kg variant now moving into production, Amprius is expanding its reach into electric aviation, defense, and next-generation mobility markets. The company’s ability to scale rapidly and meet customer demand is a major factor in its success.
Amprius’ proprietary silicon anode platform has been validated up to 500 Wh/kg and 1,300 Wh/L, demonstrating the company’s commitment to innovation and quality. With more than 1.8 GWh of secured contract manufacturing capacity, Amprius is well-positioned to meet the growing demand for high-energy density batteries.
The launch of the SiCore battery marks an exciting development in the field of lithium-ion technology. As the industry continues to evolve, Amprius is at the forefront, pushing the boundaries of what is possible with its cutting-edge innovations. With its commitment to quality, scalability, and customer satisfaction, Amprius is poised for continued success and growth in the years to come.
