About Amprius Technologies

Amprius Technologies, Inc. makes powerful batteries for drones and planes. These batteries help flying vehicles travel further and stay aloft longer. They solve energy storage problems for the aerospace and defense sectors.

What's in the Box?

  • SiMaxx Batteries: High-energy density cells produced at the company's pilot facility in California.
  • SiCore Batteries: Commercial-scale products developed through a partnership to meet high-volume market demand.
  • Customization Services: Engineering help for customers who need specific battery sizes or power levels.

Scaling the Business

  • Launched SiCore batteries commercially in Jan. 2024 to target broader addressable markets.
  • Formed the Amprius Korea Battery Alliance to access production capacity exceeding 2.0 gigawatt hours (GWh) annually.
  • Terminated a lease for a planned Colorado factory in Jan. 2026 to focus on outsourced manufacturing.
  • Amended a contract with the Defense Innovation Unit in July 2025 to reach $18.1 million in funding.

What Makes These Batteries Different?

The company uses silicon nanowire technology for the anode, the part of the battery that stores energy during charging. This design allows for higher energy density and faster charging than standard graphite lithium-ion batteries. Amprius uses a global network of manufacturing partners to scale production quickly with minimal capital investment.

The Scorecard

  • Revenue was $34.0 million in the three months ended June 30, 2026, up 126% year over year.
  • Gross profit reached $15.0 million for the six months ended June 30, 2026.
  • Net loss was $8.2 million in the six months ended June 30, 2026, down 48% year over year.
  • The company held $74.5 million in cash and cash equivalents as of June 30, 2026.
  • Market capitalization reached $2.0 billion in the second quarter of 2026.

Bottom Line

Amprius is transitioning from a research-focused firm to a commercial supplier of high-performance energy solutions for the aviation industry. Its strategy relies on silicon technology and global manufacturing partnerships to support the growing demand for electric transportation.
