About Amprius

100% Silicon Nanowire* Anode Technology Revolutionizes Lithium-ion Batteries

Amprius Technologies’ batteries deliver up to 100% higher energy density than standard lithium-ion batteries.  This means our cells provide more energy and power with much less weight and volume.

Delivering 100% Silicon nanowire* batteries today

Founded in 2008, Amprius Technologies is a pioneer and the established leader in the production of silicon anodes for high energy density lithium-ion batteries. Setting a precedent for scalable silicon anode production, Amprius developed a unique manufacturing process to grow 3D structures in a roll-to-roll system.

Research & development

Building on research at Stanford University, Amprius Technologies continually explores new ways to improve battery technology and manufacturing processes. Amprius Technologies’ batteries have established breakthrough performance with new cells approaching 450 Wh/kg over hundreds of cycles.

Quality assurance

Amprius Technologies employs a customer-focused Quality Management System. The focus on quality and the quality system has been validated through independent certification to ISO 9001.

Real world applications

Amprius Technologies has demonstrated scalable manufacturing and revolutionary performance in real world applications. The company’s game changing battery is a proven solution for advanced products and mission critical applications.

In demand

Amprius Technologies’ batteries are designed into High Altitude Pseudo Satellites (HAPS), and advanced wearables and drones. Batteries are in development for electric vehicles and robotics. Additionally, the company is scaling production capabilities to meet the growing demand.
