Aviation, the Unlikely Road to Long-range EVs

Amprius eyes drones and air taxis for lightweight battery breakthroughs. Of all the elements in the periodic table, silicon has the highest capacity for combining with lithium. It can hold 10 times as many lithium ions than the graphite anodes common in today’s lithium-ion batteries. Several carmakers and battery startups are looking at silicon anodes for the next generation of long-range, lightweight EV batteries.

This light, energy-dense battery just got independently verified

Amprius Technologies (NYSE: AMPX) today announced that its high-energy, high-power lithium-ion battery with a silicon anode platform has been verified by an independent test lab. The 500 Wh/kg, 1300 Wh/L battery’s performance was verified by Beaverton, Oregon-based Mobile Power Solutions, which checks compliance, safety, and performance. Its cell model reportedly provides >504 Wh/kg and >1321 Wh/l at 25C.

Amprius Sets New Bar For Battery Energy Density

Amprius Technologies has introduced a 500 Wh/kg, silicon-anode, lithium-ion battery, initially for use on solar-powered, high-altitude platform stations including the Airbus Zephyr. The energy density achieved is up to twice that provided by commercially available graphite-anode lithium-ion…
