Amprius announced a revolutionary new tool for high-volume manufacturing of 3D silicon nanowire anodes for high-energy lithium-ion batteries.

If it's truly revolutionary, Amprius should be closer to actual commercialization of battery cells that can store up to 1,000 Wh/L and up to 400 Wh/kg.  EVs are obviously targeted as one of the applications for the tech.

Higher denisty battery technology is key for improving range abiilities in PHEVs such as in the upcoming Hyundai IONIQ Plug-in

Demonstration of the new applications is scheduled for June 29 at a Meyer Burger facility in the Netherlands, and we look forward to the results.

"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 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."

"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"

Former Secretary of Energy Steven Chu, a Nobel Laureate and Amprius Board Member said:

“Amprius’ manufacturing demonstration is a very big step forward. 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.”

Dr. Kang Sun, Amprius CEO said:

“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. Amprius’ revolutionary new tool will accelerate Amprius’ evolution into a commercial manufacturer of high-energy batteries for drones, wearable technologies, and electric transportation.”
