WHAT WE DO
Manufacturing high-energy density batteries at scale
We’re transforming how batteries power the world. By enabling longer range, faster charging, and higher payloads, we’re driving the future of electric mobility—across air, land, and sea.
Industries
Built for high-performance applications
Prioritizing performance and reliability, our battery cells effectively power diverse industries.
We use the best material for energy density: silicon. Packing more power into a compact form, our battery cells pave the way for advancements across electric vehicles, aircraft, drones, wearables, and future markets.
With our MWh-scale manufacturing site in Fremont and GWh-scale partnerships in China—soon expanding across Asia and Europe—we’re ready to meet the growing demand from leading industries.
“In Amprius, AALTO has a highly valued partner that continues to produce ultra-high-energy density batteries that are critical to our success, enabling improvements in nighttime operations and extending coverage latitude.”
Pierre-Antoine Aubourg
Chief Technical Officer, AALTO
“Collaborating with forward-thinking partners like Amprius has been pivotal in positioning PHASA-35 as the leading solution for persistent, wide-area surveillance and communications from the stratosphere.”
