Airbus invests in battery tech firm

Airbus Defence and Space has invested in Amprius Inc to further boost the development of new generation batteries based on Silicon Nanowire Anode technology.

The goal of the investment is to help drive the development of higher volume production capacity along with higher energy density cells for Airbus Defence and Space aerospace programmes, including the Zephyr High Altitude Pseudo Satellite and Urban Air Mobility innovation initiatives.

Amprius manufactures very high energy density commercial batteries, including a 100% silicon nanowire anode, silicon-graphite composite anodes, lithium-rich cathodes, and high voltage electrolytes tailored for silicon. Its high energy density batteries are used for smartphones, wearables, drones, robotics, aerospace vehicles, electrical transportation and military equipment.

Zephyr is enabled by the latest in battery technology. Both the increase in production volumes of new generation batteries and research for future development will be used to further the Zephyr programme and build on its market position.

Jana Rosenmann, head of Airbus unmanned aerial systems, said: ‘This partnership reinforces the link between two market leaders, the newest generation batteries of the market matched with the most advanced HAPS programme.

‘Zephyr is currently the only one operating in the stratosphere at an average altitude of 70,000[ft] and running exclusively on solar power, providing persistent local satellite-like services and supporting a wide range of applications and tasks.’
