Amprius’ new silicone anode battery lineup, SiCore

January 18, 2024

Amprius Technologies, Inc., a manufacturer of next-generation lithium-ion batteries, has announced the launch of its new SiCore battery lineup.

SiCore batteries are based on a proprietary silicon anode material system, delivering up to 400 Wh/kg, and a long cycle life, with as many as 1,200 cycles at full depth of discharge, exceeding current graphite technology.

Amprius mentioned SiCore performance has been validated in various EV applications, initial samples are receiving positive feedback, and they forecast a demand of over 100 megawatt hours in the coming years.

Through an exclusive supply agreement with its partner Berzelius, Amprius has exclusive rights to use these silicon anode materials to serve the United States, Canada, and Mexico. The SiCore batteries are currently manufactured by toll manufacturing partners. The SiCore product platform complements the currently sold-out capacity of the Company’s SiMaxx silicon nanowire anode batteries, serving as a capacity bridge until the gigawatt-scale facility becomes operational.

MWh-scale quantities of SiCore products in a wider range of form factors encompassing pouch, large form factor (up to 100 Ah), and cylindrical cells are readily available for 2024 delivery to support customer demand. These products will pair with Amprius’ existing MWh capacity installed in Fremont, CA for SiMaxx. Amprius expects to produce both SiCore and SiMaxx batteries at its gigawatt-scale factory in Colorado.

Amprius has also rebranded its existing silicon nanowire platform as SiMaxxTM, which offers a product range with an energy density of up to 500 Wh/kg and 1,300 Wh/L.

Dr. Kang Sun, CEO of Amprius Technologies, said, “Leveraging our proven track record of delivering the industry’s highest commercially available energy density silicon anode lithium-ion cells to esteemed aviation customers such as AALTO/Airbus, AeroVironment, BAE Systems, Teledyne FLIR, and the U.S. Military, Amprius sees a significant opportunity with SiCore to broaden our silicon anode battery solutions today and to advance more applications across electric mobility. The global battery market size for electric mobility is projected to grow to over $100 billion by 2025, including aviation and electric vehicles. This new product platform is expected to strengthen our ability to meet customers’ volume shipment requirements immediately while presenting a drop-in solution to foster silicon anode adoption in multiple applications, allowing us to better address this growing market.”
