Novacium Unveils Cutting-Edge Prototype Batteries

In an exciting development for the energy sector, Novacium, a prominent French deep-tech company, has delivered its first batch of prototype batteries to the French Army Technical Section (STAT). This successful delivery, made in the third quarter of 2026, represents a major milestone in advancing tactical battery technology, as the new batteries are designed to offer double the energy capacity of existing units.

Significant Improvements with the New GEN3 Cells

The prototype batteries utilize GEN3 21700 cylindrical cells to replace the outdated 18650 cells that are currently in use. This strategic shift is aimed not only at increasing the energy capacity but also at ensuring that compatibility with existing military equipment is maintained. The new design delivers 144 Wh of onboard energy, which is a substantial increase from the 72 Wh provided by the current batteries in service.

An impressive increase in energy density accompanies this development, moving from 160 Wh/kg to 261 Wh/kg, thus improving the efficiency of energy storage and delivery for tactical radio sets. The engineering challenge of integrating this advanced technology while ensuring that physical dimensions remain within acceptable limits has been expertly tackled by the Novacium team.

Optimized Design for Military Application

To meet the existing equipment's requirements, Novacium limited necessary dimensional modifications while enhancing battery performance. This maximizes operational efficiency by reducing the need for extensive retraining or reconfiguration of systems that rely on the current battery systems. The enhanced battery management system (BMS), along with a newly patented enclosure design, guarantees that only minimal changes will be required to existing connectors, chargers, and interfaces.

The reduced size (42.6 × 98.63 × 74.35 mm) and lightweight design (551 g) further enhance the product's applicability in the field. These significant improvements ensure that soldiers will benefit from up to double the operating time based on similar usage profiles compared to the previous versions. The operational evaluation of these prototype batteries under real-world conditions is the next step.

Evaluation Campaign and Expected User Feedback

STAT will undertake an evaluation campaign to test the batteries under operational conditions. The feedback gathered from this assessment will be pivotal for Novacium as they prepare for the second batch of batteries. Detailed feedback reports (RETEX) will allow for vital design, ergonomic, and performance adjustments, ensuring that the final products meet the stringent requirements of military applications.

Dr. Jed Kraiem, Novacium's Chief Operating Officer, highlighted the engineering triumph this battery represents, noting the importance of user feedback to refine the technology further.

A Path to Greater Innovations in Defense Technology

The successful delivery is a testament to Novacium's commitment to transforming their expertise in anode materials into practical solutions for critical applications. If validated through the evaluation phase, these innovations could not only revolutionize tactical communications for the French military but also set the groundwork for similar enhancements for allied forces with comparable needs.

Bernard Tourillon, President and CEO of HPQ Silicon Inc., emphasized the significance of this project, showcasing the strategic value of their partnership with Novacium and the potential for further advancements in the defense sector. With plans for a second batch featuring the next-gen GEN4 cells, which surpass a capacity exceeding 6,500 mAh, Novacium is poised to continue its innovation trajectory in energy solutions for military applications.

What Lies Ahead

As Novacium moves forward, their focus will shift to scaling production based on user feedback and preparing for larger orders, including potential applications in drone technology. This is part of a broader strategy to expand their footprint in both defense and autonomous systems markets, as evidenced by their recent contracts for drone battery packs. With ongoing developments in green technologies and energy materials, Novacium stands at the forefront of a new era in military energy solutions that promises to enhance operational capabilities dramatically.

In conclusion, Novacium's innovative prototype batteries not only signify a leap forward in tactical battery technology but also reflect a comprehensive approach to military applications that prioritizes efficiency, compatibility, and sustainability. As they continue to push the envelope, the impact of such advancements will undoubtedly extend beyond military use, paving the way for advancements in commercial sectors as well.
