Amprius’s silicon nanowire batteries power the Zephyr S HAPS solar aircraft

Battery manufacturer Amprius is supplying lithium-ion cells to Airbus’s Zephyr program. Using Amprius’s cells, which contain a 100% silicon anode, the Zephyr S solar-powered unmanned aerial vehicle (UAV) recently flew more than 25 days, setting a new record for stratospheric flight. The Zephyr S is a high-altitude pseudo-satellite (HAPS), which combines the persistence of a… Read more »

Amprius demonstrates new tool for manufacturing of silicon nanowire anodes

Battery manufacturer Amprius has demonstrated a new system for inline, continuous, and roll-to-roll production of three-dimensional silicon nanowire anodes that it says will enable it to scale up manufacturing more quickly. Silicon is widely considered to be the next big thing in anode technology – battery-builders and automakers (including Tesla) are working on ways to… Read more »

NASA awards grants for advanced battery technologies

There are a number of synergies between space travel and electromobility (just ask Elon Musk). Both pursuits require energy storage devices with high energy density, stringent safety standards, and the ability to operate in high-vibration, extreme-temperature environments. Developing improved battery technology is a high priority at NASA, and the agency is making significant investments in… Read more »
