Amprius, the US-based lithium-ion battery maker, has received a $35 million repeat order for its SiCore cells from an unmanned aerial systems (UAS) manufacturer.
This follows an order made in February 2025 totalling $15 million, as well as the company shipping batteries from its pilot line to Airbus subsidiary AALTO, reported by BEST in July.
The company, which is headquartered in California, said that its silicon platform cells are made to handle the rigorous demands of UAS missions, which includes take-off through to sustained flight and landing.
Amprius said its SiCore technology improves flight times and mission ranges compared to conventional lithium-ion batteries.
It takes large-scale orders through its global contract manufacturing network, which now exceeds 1.8 GWh of secured capacity, including a strategic agreement in South Korea for adoption across the aerospace, defence, and electric mobility markets.
Its commercially available SiCore and SiMaxx platforms are said to deliver up to 450Wh/kg and 1,150Wh/L, with third-party validation of 500Wh/kg and 1,300Wh/L.
“This follow-on order of more than $35 million from an existing customer highlights both the trust we’ve built with leading drone manufacturers and the strong momentum behind our revenue and market share growth,” said Dr. Kang Sun, CEO, Amprius Technologies. “As a leading supplier of silicon anode batteries, we are delivering the performance that enables our customers to meet their most demanding mission profiles. We believe the next phase of UAS growth will be powered by advanced high-performance batteries, and Amprius’ technology, products and manufacturing capabilities uniquely position us to capture a growing share of this rapidly expanding market.”
