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 »
Former Secretary of Energy Steven Chu joins board of Amprius
Dr. Steven Chu, a Nobel Prize winner in Physics and the former US Secretary of Energy, has joined the Board of Directors of Amprius, a developer of lithium-ion batteries with operations in California and China. Amprius, co-founded by Stanford Professor Yi Cui, introduced its first generation of batteries in May 2013, and it is now… Read more »
Silicon nanowire batterymaker Amprius raises $30 million in Series C funding
Amprius, a developer of lithium-ion batteries using silicon anodes, has raised $30 million in a Series C funding round, which it will use to commercialize its batteries and further develop the next generation. The company introduced its first generation of batteries in May 2013, and is supplying smartphone and tablet OEMs with its first two… Read more »
Tesla tweaks its battery chemistry: a closer look at silicon anode development
In mid-July, Tesla Motors made a trio of Model S update announcements. The new options included a 70 kWh rear-wheel-drive base model, an upgrade for the high-end battery pack from 85 to 90 kWh (providing about a 6% increase in range), and Ludicrous mode, which offers a 10% improvement in the car’s 0 to 60… 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 »
