EnerSys : reg; ZeroVolt™ United States-Made Space Battery with Domestically Sourced Electrode Materials Enters Orbit

READING, Pennsylvania, August 12, 2021 - EnerSys^® (NYSE:ENS), the global leader in stored energy solutions for industrial applications, is proud to announce the successful launch of its high-energy, Lithium-ion (Li-ion) battery into orbit aboard the SpaceX Transporter-2 rideshare mission on June 20, 2021. The EnerSys^® Li-ion battery, featuring ZeroVolt™ battery technology, was integrated into the Spire Global^®, Inc. LEMUR-2 satellite bus. Quallion^® LLC, a division of EnerSys^® located in Sylmar, California, manufactured the battery cells using 100 percent domestically sourced electrode materials from Pyrotek^® and Forge Nano^®.

The LEMUR-2 satellite also carries two advanced payloads to provide data on global ship tracking to benefit consumers and private industry, and on atmospheric conditions to increase the amount of raw weather data for forecasts to improve weather prediction around the globe.

'Our partnership with EnerSys demonstrates the wide capabilities of the advancements that can be enabled through our space-as-a-service offerings,' said Keith Johnson, Vice President and General Manager, Federal at Spire Global, Inc. 'By integrating EnerSys ZeroVolt battery technology into our LEMUR-2 platform, we are able to gather relevant performance data in a spaceflight application and advance the use of this technology more broadly within the space industry.'

EnerSys^® ZeroVolt™ battery technology allows a battery to be discharged to a 0V potential and recharged without any performance degradation. Typical Li-ion chemistry found in Commercial-Off-the-Shelf (COTS) cells is unable to recover for a 0V discharge. The battery aboard the LEMUR-2 will be electrically cycled in-orbit at specific Depth of Discharge (DOD) levels to determine their electrical performance in a space environment as part of the battery qualification process.

EnerSys^® incorporated domestically sourced anode material from Pyrotek, headquartered in Spokane, Washington, and cathode material from Forge Nano, based in Thornton, Colorado. Both electrode materials utilized Forge Nano's Atomic Layer Deposition (ALD) coatings to improve cell electrical cycling performance.

'EnerSys is excited to play such an important role in the success of Spire Global's program and to be able to deliver our U.S.-made battery cells using domestically sourced electrode materials,' said Mark Matthews, EnerSys Senior Vice President, Specialty - Global. 'These new U.S.-made battery cells pave the way for a fully integrated U.S. battery cell supply chain at a critical time in the domestication of the battery industry,'
