Amprius Technologies, Inc. a leader in next-generation lithium-ion batteries with its Silicon Anode Platform, is once again raising the bar with the verification of its lithium-ion cell delivering unprecedented energy density of 500 Wh/kg, 1300 Wh/L, resulting in unparalleled run time. At approximately half the weight and volume of state-of-the-art, commercially available lithium-ion cells, the all-new battery cell delivers potential industry-disrupting performance with barrier breaking discharge times. Amprius’ next-generation cells are well positioned to power products in the fast-growing aviation and, eventually, electric vehicles markets, estimated to be collectively over $100 billion in battery demand by 2025.

“These cells provide a run time of 200% compared to state-of-the-art graphite cells, while being lighter and smaller than other batteries with the same energy content,” said Jon Bornstein, President of Amprius Lab. “This latest validation continues Amprius’ track record of producing the world’s most powerful battery cells and sets an industry benchmark for next-generation battery technology that will ultimately revolutionize how high we fly, how far we travel and how long we can use our devices.”

The 500 Wh/kg battery platform significantly expands boundaries for customers and is a tailored solution for applications that require maximum discharge times without compromising key features such as aircraft payload and without having to increase vehicle weight. The new batteries demonstrate both high gravimetric energy density (Wh/kg) and volumetric energy density (Wh/L) with exceptional adaptability. The customizable platform allows customers to select the option to either increase energy content in a battery pack without increasing weight, reduce weight in applications that target a fixed energy content, or combinations of both. Higher energy is important for longer run times, range and endurance, while lighter packs increase energy efficiency – even for the same battery energy content.

“We look forward to taking advantage of Amprius’ 500 Wh/kg cell to further develop Zephyr’s unrivalled stratospheric endurance capabilities,” said Pierre-Antoine Aubourg, Chief Technical Officer at AALTO HAPS, the Airbus subsidiary developing the 100% solar-electric High Altitude Platform Station for connectivity and earth observation applications. “Amprius is a valued current supplier with a great track-record, and we are confident that Amprius’ battery will deliver the capability we need.”

The record 500 Wh/kg energy density performance was verified by Mobile Power Solutions, a leading testing house offering comprehensive battery regulatory compliance, safety, and performance testing. The results indicate that this cell model provides >504 Wh/kg and >1321 Wh/l at 25��C.

About Amprius Technologies, Inc.

Amprius Technologies, Inc. is a leading manufacturer of high-energy and high-power lithium-ion batteries producing the industry’s highest energy density cells. The Company’s corporate headquarters is in Fremont, California where it maintains an R&D lab and a pilot manufacturing facility for the fabrication of silicon nanowire anodes and cells. To serve significant customer demand for its high-performance silicon anode lithium-ion batteries, Amprius recently signed a letter of intent for an approximately 774,000 square foot facility in Brighton, Colorado that initially provides a potential of up to 5 gigawatt-hours (GWh) manufacturing capacity.

Amprius’ commercially available batteries deliver up to 450 Wh/kg and 1,150 Wh/L, the industry’s highest known energy density cells available on the market today. Based on Amprius’ current level of battery performance and pilot production, the Company will be able to use its proprietary anode technology to deliver battery cells that contain energy density levels that approach 2x the performance of current commercially available graphite cells.
