Amprius Silicon Anode Lithium-Ion Battery Cell With 500 Wh/kg Density. Amprius Technologies is a battery technology company based in Fremont, California. Founded in 2008 by Dr. Yi Cui, the company specializes in developing high-energy and high-power density lithium-ion batteries. The company’s battery technology is based on silicon nanowire anodes, which offer several advantages over traditional graphite anodes, including higher energy density and faster charging times.
Amprius has received several rounds of funding from venture capital firms and strategic partners, including investors such as Intel Capital and Kleiner Perkins. The United States, Department of Energy (the DOE) has also provided funding to the company for its advanced battery research and development efforts.
Amprius’ battery technology has applications in several industries, including electric vehicles, drones, and aerospace. The company’s batteries are used in several electric aviation platforms, including the AALTO Zephyr, a solar-electric telecommunications aircraft that offers persistent earth observation capabilities from the stratosphere.
In addition to its battery technology, Amprius also offers a customizable battery platform that allows customers to adjust the specifications of the battery cell to meet their engineering needs. This includes the ability to increase energy content in a battery pack without increasing weight, reduce weight in applications targeting a fixed energy content, or a combination of the two. Let’s find out about their new battery.
Amprius New Battery -Density Of 500 Wh/kg Silicon Anode Lithium-Ion Battery Cell
Amprius got third-party verification of the performance of its battery cell, which provides great power density in a small container.
Amprius has reported that the performance of their silicon anode battery cells has been tested by third-party tester Mobile Power Solutions. The results reveal that at 25 degrees Celsius, this cell model yields 504 Wh per kilogramme and 1321 Wh per L.
The silicon anode cell, according to Amprius, is around half the weight and volume of top currently available lithium-ion batteries.
The cells have potential in the rapidly expanding electric aircraft field and could be integrated with electric automobiles in the future. According to the business, global demand for electric aviation and light-duty EV batteries is expected to top $100 billion by 2025.
The Amprius cells outperform leading graphite battery cells in terms of run duration while being lighter and smaller than other batteries with the same energy capacity.
“This latest validation builds on Amprius’ track record of developing the world’s most powerful battery cells and creates an industry benchmark for next-generation battery technology that will eventually revolutionise the automotive sector.” how high we fly, how far we travel, and how long our devices can be used,” said Jon Bornstein, president of Amprius Labs.
Clients can modify characteristics on the battery cell platform to match the engineering requirements of their project. Customers can choose between increasing energy content in a battery pack without increasing weight, reducing weight in applications that seek a fixed energy content, or a combination of the two. Longer run times, range, and endurance take more energy, however lighter packs enhance energy efficiency.
The battery cells will be integrated into the AALTO Zephyr, a high-altitude platform station (HAPS). With an 18cm ground sampling distance and near-real-time video and pictures from the stratosphere, the solar-electric telecommunications aircraft provides continual earth observation day and night.
“We are excited to use Amprius’ 500 Wh/kg cell to further expand Zephyr’s unrivalled stratospheric endurance capabilities,” stated Pierre-Antoine Aubourg, chief technical officer of Airbus subsidiary AALTO HAPS. “Amprius is a trusted current source with a proven track record, and we are convinced that their battery will meet our requirements.”
In Fremont, California, Amprius has a research and development laboratory. It has signed a statement of intent for a 774,000 square foot facility in Brighton, Colorado, with a manufacturing capacity of up to 5 GWh.
The DOE seeks to improve battery performance in order to sustain the crucial materials supply chain and provide appealing goods to vehicle buyers. ” “While there are presently a number of electric drive vehicles on the market,” the DOE notes, “future advancements in battery technology could make them more inexpensive and convenient to consumers.” In order to achieve these objectives, the DOE funds improved battery development, systems analysis, and testing.
