Amprius Technologies has announced an expansion of its product portfolio of silicon anode batteries. The new SiCore batteries are based on a proprietary silicon anode material system. Amprius claims its batteries deliver performance that surpasses that of today’s state-of-the-art graphite-based cells: specific energy up to 400 Wh/kg, and cycle life up to 1,200 cycles at full depth of discharge.

“Leveraging our proven track record of delivering the industry’s highest commercially available energy density silicon anode lithium-ion cells to aviation customers such as AALTO/Airbus, AeroVironment, BAE Systems, Teledyne FLIR, and the US military, Amprius sees a significant opportunity with SiCore to broaden our silicon anode battery solutions today and to advance more applications across electric mobility,” said Amprius CEO Dr. Kang Sun.

Amprius says its SiCore silicon anode battery performance has been validated across various applications in the e-mobility market. Amprius has been sampling the SiCore products with customers for several months, and initial samples have garnered positive feedback from customers with demanding performance requirements.

Through a toll manufacturing agreement with its partner Berzelius, Amprius possesses exclusive rights to use these silicon anode materials to serve the US, Canada and Mexico. This arrangement allows Amprius to use existing manufacturing capacity at partner sites to offer a wider range of form factors. MWh-scale quantities of SiCore products are available for immediate delivery to support customer mass production scale-up. Amprius intends to produce both SiCore and SiMaxx batteries at its gigawatt-scale factory in Colorado, set to commence operations in 2025.

“This alignment with a proven large-scale manufacturing partner positions us to deliver superior battery performance while leveraging their existing production lines,” added Dr. Sun. “SiCore allows us to support our customers’ roadmaps and demands while we execute on our plans for our large-scale facility in Colorado, all without diverting capital from the US scaling effort.”
