Amprius Technologies was awarded a CES Innovation Award in the Sustainability & Energy Transition category for its 520 Wh/kg silicon‑anode battery, a record‑setting energy density that enables electric aviation customers to achieve more than twice the flight time of conventional cells while keeping the same weight.
The 520 Wh/kg rating places Amprius’ SiCore cells at the top of the commercial battery market, giving the company a clear technical advantage in high‑performance applications such as electric aircraft, drones, and other electric mobility solutions. The award underscores the company’s ability to translate laboratory breakthroughs into production‑ready products that meet the stringent safety and reliability standards of the aviation industry.
In December 2025, Nokia announced it would use Amprius SiCore cells in its new drone‑in‑a‑box platform, marking Nokia’s first deployment of silicon‑anode technology. The partnership validates the commercial viability of Amprius’ batteries and opens a sizable market for the company’s high‑energy‑density cells in the rapidly growing drone sector, which is expected to reach multi‑billion‑dollar revenues over the next decade.
Amprius’ financial performance in the most recent quarter (Q4 2023) showed revenue of $3.94 million, beating analyst estimates, and an earnings per share of –$0.11, which met consensus expectations. The company’s revenue growth reflects strong demand from its core aviation and drone customers, while the earnings figure highlights the ongoing investment required to scale production and support new product introductions. Management has emphasized disciplined cost control and a focus on high‑margin segments to improve profitability as the company expands its manufacturing footprint.
CEO Dr. Kang Sun said, “The CES award and Nokia partnership confirm that our silicon‑anode technology delivers the performance and reliability that our customers demand. These milestones reinforce our strategy to become the leading provider of high‑energy‑density batteries for electric aviation and beyond.”
Investors have responded positively to the award and partnership, with a 7‑day return of 17.4% after a 30‑day decline, and a 1‑year total shareholder return of 159.6%. The market reaction reflects confidence in Amprius’ technology leadership and its expanding commercial footprint.
