Amprius Technologies, a developer of next-generation lithium-ion batteries using its Silicon Anode Platform, has completed its qualification process for its centrotherm mass production deposition tool to manufacture silicon nanowire anodes.

This marks a pivotal step in ramping production capacity to meet the growing demand for its ultra-high-energy SiMaxx cells in electric mobility applications.

Throughout its capacity expansion in Fremont, Amprius has been working on its anode fabrication process for the centrotherm tool to achieve the targeted silicon anode performance necessary for Amprius to begin shipping commercial cells.

Amprius’ demand pipeline is robust with current SiMaxx capacity sold out through 2024. With this qualification process complete, Amprius is able to complement the company’s existing roll-to-roll systems with the centrotherm tool. This enables an increase in SiMaxx shipments as Amprius advances its Fremont, California, production ramp to 2 MWh, representing approximately a 10X increase in capacity online exiting 2024.

This achievement signifies a crucial advancement in scaling up production capacity to address the increasing need for our ultra-high-energy cells in electric mobility applications. Our primary focus in Fremont is to supply high-energy cells to meet this demand. The successful qualification of our production solution not only accelerates our ramp-up in Fremont this year but also prepares us to manufacture SiMaxx at our gigawatt-hour-scale factory in Brighton, CO.

In addition to internal validation, Amprius has garnered support from industry partners such as BAE Systems.
