Enovix Awarded Follow-On Contract to Build Wearable Battery Cells for U.S. Army Soldiers

Aug 10, 2022

FREMONT, Calif., Aug. 10, 2022 (GLOBE NEWSWIRE) -- Enovix Corporation (“Enovix”) (Nasdaq: ENVX), the leader in the design and manufacture of next generation 3D Silicon™ Lithium-ion batteries, today announced that it has been awarded a follow-on contract to build and test custom cells for use within U.S. Army soldiers’ central power source, called the Conformal Wearable Battery (CWB). Created by Inventus Power, the CWB integrates into a soldier’s vest and powers vital communications and navigation equipment.

The goal of this project is to evaluate the performance and safety of Enovix 3D Silicon Li-ion cell technology and assess its alignment to the CWB. This effort is awarded under GTS’ prime contract W56KGU-18-C-0025 and follows the initial demonstration phases for the U.S. Army’s Center’s DOTC-17-01-INIT1218 Advanced Power Systems Technologies with the Department of Defense, which was announced last year. It was awarded in conjunction with Inventus Power, a leading provider of advanced battery and power systems that specializes in the design and manufacture of lithium-ion battery packs for both military and commercial applications. Enovix expects to begin shipping first cells to Inventus Power in 2023.

“We’re proud to move to the next stage of our work with Inventus Power on the U.S. Army program, a major milestone attributed to our breakthrough battery and its ability to provide high energy density in a safe, ruggedized and lightweight format,” said Harrold Rust, Co-Founder, President and Chief Executive Officer of Enovix. “Soldiers in the field need reliable, lightweight and long-lasting batteries and we’re thrilled Enovix has been chosen to demonstrate the advantages of our domestically-manufactured technology.”

“Safety is a top priority at Inventus Power and when we tested the Enovix battery cells with its BrakeFlow technology, the results were impressive,” said Chris Turner, CTO of Inventus Power. “Enovix batteries are the only next-gen, high energy density cells to pass our nail penetration test. We look forward to collaborating with the company on this program, to provide an even more resilient, high-energy battery to the U.S. Army.”

The Enovix cell has the potential to nearly double the energy density of the current CWB, which could result in substantial operational advantages including a longer lasting battery. Another key advantage for the Army is BrakeFlow™ technology, a breakthrough in battery safety, made possible due to the company’s unique battery architecture.

“Enovix is honored to continue working with Inventus Power on the U.S. Army program to provide mission-critical technology that includes BrakeFlow, which ushers in a new level of safety in advanced, lithium-ion battery design,” said Cam Dales, GM and Chief Commercial Officer. “BrakeFlow can significantly limit overheating during an internal shorting event, which is a primary cause of battery fires. Additionally, our batteries are well-suited for rugged environmental conditions due to the mechanical robustness of our proprietary architecture. This is another example of what sets us apart from other advanced battery manufacturers.”

The average U.S. soldier carries anywhere from 60-200 pounds of gear, with batteries making up roughly 15-20 pounds of that overall load. These batteries are crucial to the needs of the modern soldier, powering a range of vital communications, weapons and tactical applications. CWBs with Enovix battery cells for the U.S. Army have the potential to meet these needs and more, providing a range of advantages over already in-use systems, including:

  • a dramatic increase in energy density supporting longer missions in the field;
  • streamlined power supply within a single system, powering more devices while decreasing the need for additional batteries to lighten a soldier’s overall carrying load; and
  • Enovix’s unique battery architecture that enables innovations like BrakeFlowTM technology, an intra-cell system that significantly increases tolerance against thermal runaway from internal shorts, without compromising high energy density.

While the CWB is produced by Inventus Power at its U.S. manufacturing facility, the cells for CWBs have traditionally been developed and sourced internationally, since there are limited qualified options in the domestic battery supply chain. Both Inventus Power and Enovix are advocates of strengthening the battery industry ecosystem within North America and increasing manufacturing capacity to support critical EV-adjacent markets (i.e. military). Enovix aims to manufacture CWB cells at its U.S.-based factory, strengthening the American battery supply chain while also supporting American national security needs.

Enovix believes the total U.S. wearable military battery market is approximately $350 million annually based on currently established military programs, of which the CWB is a majority.
