British defense contractor BAE Systems has entered into a three-year cooperation agreement with lithium-ion battery developer Amprius Technologies, the companies announced last week. Amprius will supply BAE with lightweight and high-energy batteries for electric aviation applications, while leaving the door open to other possible uses in BAE’s defense technologies. 

Amprius is a Fremont, California-based company developing high-energy lithium-ion batteries with silicon nanowire anode technology. The company claims that its batteries deliver the highest energy density of any existing lithium-ion batteries.
