Amprius Technologies has claimed the verification of its lithium-ion cell can deliver energy density of 500 Wh/kg, 1300 Wh/L.
Amprius’ next-generation cells are 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.
The 500 Wh/kg battery platform 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 adaptability.
Amprius Technologies Customizable Platform
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,
- 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 in a press release, 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,” Aubourg added.
The record 500 Wh/kg energy density performance was verified by Mobile Power Solutions, a 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.
