Amprius to showcase its silicon nanowire battery manufacturing line in December

Amprius Technologies, a developer of next-generation lithium-ion batteries with its Silicon Anode Platform, will host an event for customers, vendors, investors and partners to showcase its expanded production facility—known as Amprius Lab—in Fremont, California.

Amprius is increasing its capacity by 10x at its Fremont facility through the commissioning of its proprietary anode production line, moving the company from kWh of production to MWh of production.

This additional capacity will serve existing customers, including Airbus, AeroVironment, BAE Systems, and Teledyne FLIR, as well as supply the backlog of new customers seeking cell qualification in 2024. The facility will manufacture high-energy batteries delivering energy densities of up to 500 Wh/kg and 1335 Wh/L, and high-power batteries with discharge rates as high as 10C.

The company’s current commercially available batteries deliver up to 450 Wh/kg and 1,150 Wh/L.

During the event, invitees will have the opportunity to engage with Amprius executives on the expansion’s impact and observe the manufacturing equipment. All new assembly and dry rooms will be available for viewing—along with mass production anode equipment, the same technology planned for the GWh factory.

Due to relentless customer demand for our cells, our current capacity is fully committed for the next 12-18 months. The expanded production in Fremont will enable us to meet the escalating demand from our valued customers while significantly enhancing our ability to support a larger number of new customer qualifications.

This marks a pivotal moment for Amprius. Establishing turnkey manufacturing processes featuring next-generation solutions for our proprietary silicon anode cell manufacturing will allow us to fulfill customer demand while we prepare our Colorado GWh factory for scale up in 2025.

—Jon Bornstein, President of Amprius Lab

Amprius’ next-generation cells are well positioned to power products in the fast-growing aviation and, eventually, electric vehicle markets, estimated to be collectively more than $100 billion in battery demand by 2025.
