Former Secretary of Energy Steven Chu: “A very big step forward”
SUNNYVALE, CA – Amprius, a leading manufacturer of high-energy lithium-ion batteries, has demonstrated a revolutionary new tool for high-volume manufacturing. The new tool, a first-of-its-kind system for inline, continuous, and roll-to-roll production of three-dimensional silicon nanowire anodes, will enable Amprius to scale manufacturing and deliver lightweight and long-lasting batteries for unmanned vehicles, wearable technologies, and electric vehicles.
“Amprius’ manufacturing demonstration is a very big step forward,” said former Secretary of Energy Steven Chu, a Nobel Laureate and Amprius Board Member. “In recent years, Amprius’ silicon anode technology has enabled batteries with ultra-high energy. This year, Amprius’ new tool is a significant advance towards high-volume and high-quality manufacturing.”
Amprius developed its new tool in partnership with Meyer Burger (Netherlands) B.V., a world leader in high-throughput deposition systems and processes. The tool uses a multi-step, Chemical Vapor Deposition (CVD) process to produce Amprius’ silicon nanowire anodes. Because silicon offers far more energy than carbon, the conventional anode material, Amprius’ batteries achieve significantly higher energies per unit volume (800 – 1,000 Wh/L, depending on cell capacity and form-factor) and energies per unit weight (325 – 400 Wh/kg) than today’s commercially available batteries.
“Inline, continuous, and roll-to-roll manufacturing will enable Amprius to transition high-energy batteries from lab to market, and from batch processing to pilot production,” said Dr. Kang Sun, Amprius CEO. “Amprius’ revolutionary new tool will accelerate Amprius’ evolution into a commercial manufacturer of high-energy batteries for drones, wearable technologies, and electric transportation.”
Amprius will unveil its manufacturing tool to a select group of industry partners on June 29, 2016, at a Meyer Burger facility in the Netherlands. To request an invitation, please email email@example.com.
