AS9100:2016, an international standard specific to the aerospace sector, enhances ISO 9001:2015 requirements to ensure that products align with stringent customer and regulatory requirements. To earn this certification, Amprius’ recently expanded Fremont facility underwent a rigorous evaluation process and audit. As a part of the evaluation process, Amprius has also successfully renewed its ISO9001:2015 certification, a globally recognized standard for quality management systems (QMS).

“The AS9100 certification reinforces Amprius' unwavering commitment to delivering high-quality silicon anode batteries to the aerospace and defense industries,” said Aaron Bakke, Amprius Lab VP of Operations. “We take pride in providing customers with industry-leading, ultra-high energy density silicon anode batteries that surpass currently commercially available solutions. With this certification in hand, we’re now able to continue our dedicated pursuit of setting the industry standard for performance, product quality, delivery, and cost.”

Amprius collaborated with Smithers Quality Assessments, an accredited quality and environmental registration agency, to achieve these certifications. Each certification is valid for three years.
