Amprius Technologies selects Colorado for new 5-GWh lithium-ion battery plant to serve EV market

The Fremont, CA-based manufacturer of lithium-ion batteries with its Silicon Anode Platform signs a letter of intent for a 775,000-sq-ft facility in Brighton, CO. The factory, targeted to be operational in 2025, will be built in phases starting with an initial 500 megawatt-hours (MWh) with the potential of up to 5 gigawatt-hours (GWh) within the initial footprint. This capacity increase is a significant expansion to Amprius’ manufacturing capacity and will serve strong customer demand for its high-performance, silicon-anode, lithium-ion batteries.

Amprius selected Colorado for its high-volume manufacturing facility following an extensive evaluation of key criteria across three states. Specifically, the location has a 1.3-million-sq-ft existing factory site (above) equipped with the electric power and structural layout ideal for a gigawatt-hour scale lithium-ion battery factory, reducing expected build-out costs. Also, this facility is in closer proximity to essential materials, as well as critical transportation infrastructure, together limiting logistical and operational costs. Overall, this site exceeded the company’s requirements and is expected to both streamline time-to-market and drive effective customer fulfillment.

“The selection of Colorado for our gigawatt-scale factory marks an important milestone for Amprius,” says Dr. Kang Sun, CEO-Amprius Technologies. “We worked closely with the state of Colorado, the Colorado Economic Development Commission, Adams County, and the City of Brighton to align on terms that are mutually beneficial and include a comprehensive incentive proposal. Increasing production to meet the substantial market demand for our breakthrough silicon anode lithium-ion technology remains a priority, and we are confident this factory will allow us to scale and effectively serve the electric mobility market.”

To further intensify the focus on product and technology development and the emphasis on manufacturing scale up, the company has formed two business units. Amprius Fab, to be located in Brighton, CO, will focus on large-scale manufacturing of silicon-anode batteries, and Amprius Lab, located in Fremont, CA, will focus on advanced battery technology, product, and manufacturing process development.
