Spire Global deploys and operates US-made battery in orbit for US Space Force

Spire Global has successfully delivered a U.S. Space Force Space Systems Command (SSC) payload to space aboard its 3U LEMUR CubeSat. The satellite has been operating nominally since July 2021 and is performing on-orbit experiments to collect payload performance data. SSC, through their Science and Technology Directorate (SSC/ZAD), awarded Spire this mission under the Small Business Innovation Research (SBIR) program.

Spire modified the power system of the satellite to successfully integrate ZeroVolt 18650 battery cells provided by EnerSys?, a global leader in stored energy solutions for industrial applications.

On June 30, 2021, a Falcon 9 launch vehicle deployed the nanosatellite into Spire's on-orbit constellation, where Spire has been successfully conducting power system discharge tests to gather operational performance data on the battery cells and build flight heritage for this novel Lithium-ion technology produced by EnerSys.

"The development of space-as-a-service offerings presents the larger space, science, and technology fields with opportunities to conduct research and development over a significant period of time at low-cost, opening the possibility of space to a wider audience than ever before," said Theresa Condor, Chief Operating Officer, Spire Global.

"Traditional payloads can take years to get into orbit. At Spire, we have the ability to send up customer payloads within a matter of months, providing a fast, reliable, and efficient option for those interested in on-orbit research."

This mission demonstrates the rapid integration and operation of science and technology experiments through Spire's space-as-a-service model. In a period of 12 months, Spire integrated the high energy, long life EnerSys ZeroVolt Lithium-ion battery cells into the nanosatellite and deployed it on orbit.

"Working with Spire on this mission has provided us with an opportunity to quickly and responsibly place our ZeroVolt battery cells into orbit so that we may conduct testing and gather operational performance data," said Joseph Troutman, Manager of Business Development at EnerSys.

"We will be able to further our battery capabilities and continue to provide satellite and military applications with world-class battery power to support mission success."

The SBIR program is a highly competitive initiative which awards funding to domestic businesses and aims to stimulate technological innovation, meet federal research and development needs, and more. SSC awarded this SBIR to Spire as a Phase II program. Phase II program funding is based on results achieved in Phase I and the scientific and technical merit and commercial potential of the project proposed in Phase II.

A carbon-air battery as a next-generation energy storage system
Tokyo, Japan (SPX) Dec 20, 2021
One of the barriers to generating electricity from wind and solar energy is their intermittent nature. A promising alternative to accommodate the fluctuations in power output during unfavorable environmental conditions are hydrogen storage systems, which use hydrogen produced from water splitting to generate clean electricity. However, these systems suffer from poor efficiency and often need to be large in size to compensate for it. This, in turn, makes for complex thermal management and a lowered ... read more
