Amprius Technologies, Inc. has announced the shipment of the first commercially available 450 Wh/kg, 1150 Wh/L lithium-ion battery cells to a company creating a new generation of High-Altitude Pseudo Satellites (HAPS). Amprius Technologies says its high-energy density battery cells have enabled capabilities in long endurance, communications and high-resolution imaging to cutting-edge stratospheric platforms since 2018.

To support surging demand, Amprius Technologies says it has embarked on constructing its first high-volume manufacturing facility located in the United States. A mass production site will be selected in the first quarter of 2022.

The U.S. Department of Energy (DOE) has announced another $48 million in funding to improve the reliability and resiliency of the U.S. power grid. This batch of funding will support a new program focused on developing power grid technologies that improve control and protection of the domestic power grid. The agency says outages caused by extreme weather events are estimated to cost the U.S. economy $150 billion annually. This new effort by DOE will fund projects that aim to enable utilities to more effectively control grid power flow to avoid disturbances, and quickly isolate and route around disruptions.
