Amprius Technologies, a California-based company that emerged from a research project at Stanford University, announced today that an independent test lab has verified the performance of its high-energy, high-power lithium-ion battery with a silicon anode platform. The battery, which boasts a capacity of 500 Wh/kg and 1300 Wh/L, was tested by Mobile Power Solutions in Beaverton, Oregon. The lab assessed the battery’s compliance, safety, and performance and found that its cell model provides over 504 Wh/kg and over 1321 Wh/L at 25C.
In simpler terms, Amprius’ battery cell has a runtime that is 200% longer than graphite cells, despite being smaller and lighter than batteries with the same energy content. According to Jon Bornstein, president of Amprius Lab, the unique design of the battery using silicon nanowires instead of graphite anodes enables higher energy density. This means that Amprius’ batteries can store more energy in the same amount of space compared to traditional batteries.
This latest verification by an independent test lab is a significant milestone for Amprius Technologies and its shareholders, as it validates the company’s groundbreaking technology. With its high-energy, high-power lithium-ion battery, Amprius is poised to make significant strides in the energy storage industry, providing a more efficient and sustainable solution for the future.

In the past he has said that electric flight starts to get interesting once you hit 400wh/kg https://t.co/eHL9ibS5Le

Amprius offers a customizable battery platform that allows customers to choose between increasing energy content in a battery pack without adding weight, reducing weight in applications that require a fixed energy content, or a combination of both. The higher energy content enables longer run times, range, and endurance, while lighter packs improve energy efficiency, even for the same battery energy content.
Pierre-Antoine Aubourg, the CTO of AALTO HAPS, an Airbus subsidiary that is developing a fully solar-electric high altitude platform station for connectivity and earth observation applications, praised Amprius as a valued supplier with an excellent track record. He expressed confidence that Amprius’ battery would meet their needs.
In March, Amprius revealed that it had signed a letter of intent for a 775,000-square-foot facility near Denver with plans to supply batteries to the aviation and eventually the EV markets.
