Amprius verifies its high-energy, high-power lithium-ion battery

California-headquartered Amprius Technologies announced its high-energy, high-power lithium-ion battery with a silicon anode platform 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 vehicle 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.

In addition, the 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 a combination 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 unrivaled 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 battery platform was verified by Beaverton, Oregon-based Mobile Power Solutions, which checks compliance, safety, and performance. Its cell model reportedly provides >504 Wh/kg and >1321 Wh/l at 25C.
