Amprius expands its silicon nanowire anode megawatt-hour production line

By Michelle Froese | December 20, 2023

More than 90 attendees attended Amprius’ Next-Generation Technology and an Exclusive Factory Tour on December 14th, 2023 for a preview of the company’s advanced anode production line.

Amprius Technologies a provider of next-generation lithium-ion batteries with its Silicon Anode Platform, recently showcased its expanded production line in Fremont, California, known as Amprius Lab. Through the commissioning of the company’s proprietary anode production line, Amprius is increasing its capacity by 10 times at its Fremont facility — moving the company from kWh to MWh scale of production.

The additional capacity will serve existing customers, including Airbus, AeroVironment, BAE Systems, and Teledyne FLIR, as well as supply the backlog of new customers seeking products in 2024. The factory will manufacture high-energy batteries, expected to deliver energy densities of over 500 Wh/kg and 1300 Wh/L, and high-power batteries with discharge rates as high as 10° C.

“Amprius’ batteries play a key role in Fremont’s dedication to technological innovation, especially in electric mobility, where our community boasts one of the highest densities of EV chargers per zip code,” said Fremont Mayor Lily Mei. “The decision by Amprius to expand within Fremont highlights our city’s commitment to pioneering next-generation technologies that are shaping the future of sustainable transportation.”

Amprius’ state-of-the-art manufacturing line features all-new assembly and dry rooms, as well as the same mass production anode equipment technology planned for the GWh-scale factory.

“The expansion of our Fremont facility is an important milestone for our business as we significantly bolster our capacity to meet the increasing demands of our esteemed customers while at the same time serving more customers,” said Dr. Kang Sun, CEO of Amprius. “As we implement advanced manufacturing processes for our proprietary silicon anode cell production, we’ll be able to lay the foundation for our gigawatt-scale factory that we expect to be operational in 2025.”

Amprius continues to expand its advanced manufacturing capabilities to meet the ever-increasing demand for its high-performance batteries. It remains well positioned to support the fast-growing aviation and, eventually, mainstream EV markets, estimated to be collectively over $100 billion of battery demand by 2025.
