Testing highlights new performance features that may enable longer battery life, deeper discharge, and improved military logistics storage
ORLANDO, FL, UNITED STATES, March 18, 2026 /EINPresswire.com/ — C-BATT™ will present new research on its Obsidia™ advanced lithium-ion battery anode material at the International Battery Seminar & Exhibit (IBSE), taking place March 23-26 in Orlando, Florida. IBSE is one of the leading global conferences focused on battery materials, cell design, and energy storage technologies.
The poster presentation introduces new data indicating that Obsidia combines high lithium storage capacity with exceptionally low volumetric expansion during charge and discharge. This combination may enable longer cycle life, improved structural stability inside the electrode, and greater tolerance to demanding operating conditions.
Recent measurements conducted by Dr. Akihiro Kushima and his research group at the University of Central Florida show that Obsidia particles expand only about 2-5 percent during lithiation and delithiation. Conventional graphite anodes typically experience roughly double that expansion during initial cycling. Lower mechanical strain inside the electrode can reduce cracking, particle breakdown, and degradation mechanisms that limit battery lifetime.
In addition to low expansion, testing indicates that Obsidia can deliver lithium storage capacity exceeding 500 mAh per gram, significantly higher than traditional graphite anodes. The material achieves this performance while maintaining a stable, amorphous, silicon-oxygen-carbon structure that accommodates lithium without the large structural changes seen in conventional silicon-based anodes.
The material also demonstrated unusual tolerance to deep discharge and low-voltage conditions. This characteristic may allow lithium-ion cells to operate safely across a wider voltage range, while reducing risks associated with copper dissolution and other degradation mechanisms that occur when batteries are discharged too deeply.
Low-voltage robustness has important implications for defense and field applications. Batteries that can tolerate deeper discharge and extended storage at low state of charge may provide longer shelf life in military logistics systems and greater durability in harsh operating environments where battery packs may be stored, transported, or used intermittently. Improved tolerance to low-voltage conditions may also simplify battery handling during transport and assembly.
“Our goal is to develop an anode material that improves energy storage performance without requiring complex manufacturing changes,” said Bill Easter, Vice President of C-BATT. “Obsidia is designed to bring unique value for defense systems that demand long storage life and deep cycle field reliability, as well as increasing return on investment via longer life at deeper cycling in grid energy storage applications, without sacrificing energy density.”
Obsidia is produced using polymer-derived ceramic processing combined with domestically sourced carbon-bearing materials. This approach allows the anode material to be manufactured entirely within the United States, supporting a secure domestic supply chain for advanced battery components.
C-BATT is also collaborating with Argonne National Laboratory to further evaluate the electrochemical performance and safety characteristics of the material under controlled laboratory testing conditions.
Unlike many emerging anode technologies that require major manufacturing changes, Obsidia is designed for compatibility with conventional lithium-ion electrode processing methods. This may allow battery manufacturers to incorporate the material into existing production lines without specialized equipment.
IBSE Presentation Team
Members of C-BATT’s technical and commercialization team will be present at IBSE to discuss the poster presentation and ongoing development work, including:
